Flame malware continues to burn

Written By Unknown on Senin, 17 September 2012 | 12.07

Over the past couple of years a new breed of malware has been making headlines. These new attacks are very complex, and seem to be directed at precision targets of national or military significance—suggesting that they've been developed by nation-states as cyber weapons. New information suggests that these threats may have been developed much earlier than previously thought, and that some of the malware attacks are still evolving and/or have not yet been discovered.

Stuxnet, Duqu, and Flame all seem to be highly sophisticated malware platforms. A coalition of security researchers has been diligently working to unravel Flame, figure out what makes it tick, and learn more about its origins and purpose. The results of the investigation are intriguing and seem to create as many questions as they answer.

According to the Flame investigation, the developers worked very hard to disguise Flame as a legitimate CMS (Content Management System) platform. The data captured by Flame is heavily encrypted on the server using strong public key cryptography to ensure that only the attackers can access it. Your average malware developers don't generally go to such lengths to protect the stolen data—supporting the idea that Flame is not your average malware.

As interesting as the inner workings of Flame might be, the researchers uncovered some other information which broadens the malware mystery. The researchers have determined that Flame is actually only one of at least four different malware strains referenced in the source code—and the other three are as yet undiscovered.

It turns out that Flame is not the most recent of the threats managed by the Flame command and control (C&C) servers. The most recent of the threats is dubbed IP, and there is evidence that another threat called SPE is currently active in-the-wild. The researchers also determined that the malware code is still evolving, and there is a new protocol—"Red Protocol"—that is not yet fully implemented.

From a cyber security and malware forensics perspective, this is all very interesting. But, what does it mean for you?

The answer is "Possibly nothing."

By all means, you should still have a reliable cross-device security platform in place to protect your PCs, tablets, smartphones, and any other applicable devices from malware and malicious attacks. But, these threats appear to be designed by nation-states, and targeted specifically at enemy nation-states. Unless you happen to be a nation-state, you probably have little to be concerned about.

However, as more of these sophisticate threats are discovered and reverse-engineered by security researchers, the tricks and techniques that make them tick become public knowledge. That means that your average cyber criminal malware developers might learn a thing or two and apply some of the innovations from threats like Stuxnet, Duqu, or Flame in future malware attacks that are aimed at businesses and consumers.

The bad news is that these threats seem to have done a very good job of spreading in stealth and flying under the radar for quite a while before being discovered. The good news is that as the techniques used are unraveled, the security vendors get to learn about the innovative techniques at the same time as the malware developers, so as long as you keep you security software up to date you should be reasonably protected.

Do you really need a DSLR?

You love to take photos. Your photos get compliments from family and friends and—don't be modest—you like them yourself. But when you compare them to some of the stuff in National Geographic, it's obvious that the fixed-lens, compact camera you're shooting with is holding you back. You think that a newer, bigger, interchangeable lens camera like the pros use will help you take your photos to the next level. You need to step up to a DSLR.

At least, that's what the makers of the big cameras want you to think. But before you reach for your credit card, make sure you aren't just suffering from technolust.

The bigger sensor, interchangeable lens cameras produced today under various acronyms—DSLR (Digital Single-lens Reflex), DSLT (Digital Single Lens Translucent), MFT (Micro Four-Thirds), and EVIL (Electronic Viewfinder with Interchangeable Lens)—are mostly terrific cameras. But every technological decision is a compromise, and compared to the best compact, fixed-lens cameras, the bigger cameras have cons as well as pros. Shooting with a bigger camera when you don't really need one is not just expensive, it may actually produce worse photos than you were taking before. It can even dampen your interest in photography. Here are a few things to consider.

1. More control means more work Bigger cameras generally have many more options than compact cameras and while compact cameras hide many of their options in the menus, bigger cameras put more controls on the outside of the body in the form of buttons, switches, and dials. Getting comfortable with these controls is like learning to drive a car with a stick shift—but much harder.

2. Blurry, fuzzy photos Other things being equal, the bigger sensors in DSLRs mean shallower depth of field, and this means, among other things, that minor autofocusing errors matter less to a compact camera than they may to a larger one.

Then there's the problem of blur caused by camera movement. Most compact cameras have some kind of image stabilization built in. A hand-held camera is never as steady as one mounted on a tripod; image stabilization reduces the number of photos ruined by the camera movement. Sony and Pentax DSLT/DSLR bodies have image stabilization built in, but the more popular Canon and Nikon DSLRs do not. Getting image stabilization with these brands requires using special stabilized lenses, and the DSLR you purchase might or might not come with such a lens.

Snapshot of Ruthie taken with the Sony DSC-RX100. The RX100 fits in a pocket easily but it has a larger sensor than most compacts, which means it's possible to get the shallow depth of field (illustrated here) that portrait photographers often like. William Porter

3. Interchangeable lenses mean money—and dust The lens is arguably a more important factor in the technical quality of your photos than the body it's attached to. Pros buy interchangeable lens cameras so they can use the best lens for each session. But the ability to change lenses is a mixed blessing for the average photographer.

For one thing, the lens on a high-end compact camera may be better than the lens on a low-end DSLR. For example, the fixed lens on my Panasonic Lumix LX5 is made by Leica and it's a really good lens: optically superior, fast (f/2.0), with a terrific zoom range. The 18-55 f/3.5-5.6 kit lens that comes with the average new DSLR, on the other hand, is probably decent but not great.

You can usually buy just the body and purchase a really good lens separately. But you might end up paying as much for the lens as for the body—or more. And that's just your first lens. To get the most out of your interchangeable lens system you'll want to buy more lenses, as good as you can afford. Most serious photographers spend a lot more money on lenses than on bodies.

And of course, changing lenses introduces a serious new problem: dust. When you change lenses, you expose your camera's sensor and mirror to dust. Dust on the sensor can mar your photos; cleaning your sensor can be expensive, or at least a pain in the neck.

4. Small is beautiful, bigger is bigger Bigger cameras are less portable and especially if you're an amateur shooting when the spirit hits you, there's wisdom in the saying that "The best camera is the one you have with you." Time and time again, I've seen people buy a DSLR and play with it for a while, then put it on the shelf and go back to using a compact camera for daily shooting. And this makes sense to me. I use my DSLRs for work. But I carry a point and shoot camera with me everywhere.

5. Workarounds defeat the purpose Yes, some of these problems have workarounds. Your DSLR doesn't have to be difficult. You can't get rid of all those buttons on the outside but you can ignore them and just use the camera in Auto or P mode. You can slap a "superzoom" (18-250mm or similar) lens on your DSLR and never take it off.

But if you do this, you're surrendering nearly all of the peculiar advantages of the DSLR. What you've got now is basically a heavier, less portable, and more expensive point and shoot. And since superzoom lenses aren't as good optically as fixed focal length lenses, or even zooms with a shorter zoom range, it won't even be a particularly good point and shoot.

Mrs Juanita Edwards at 95, taken with a Panasonic DMC-FZ35. The FZ35's sensor is smaller than the Sony RX100's and much smaller than the sensors in DSLRs, so, with the FZ35, you get lots of depth of field whether you want it or not. The upside is that you can count on your photos to be well focused in the central areas.William Porter

6. Shoot well and be happy It's possible that you're one of those people who truly does need a big sensor, interchangeable lens camera. I've daydreamed about shooting a wedding with my LX5 but I would never actually do it. The camera is a tool and certain jobs require certain tools.

But if, like most people, you mostly photograph your kids, your pets, your friends, and your vacations, then at least consider the possibility that you might be happier with a good compact camera.

A $400 food processor won't make you a better cook, and by the same token, if you can't take great photos with a Panasonic LX5, a Canon G12, or the slightly pricier Sony RX100, trust me, you won't be able to take great photos with a much pricierSony A77, Canon 7D, or Nikon D7000.

If you really want to improve your photos, buy a good book on photography or take a course. Or simply take your next vacation someplace really beautiful. You'll be amazed at how much better your photos turned out.

Panasonic Lumix GH3 adds video enhancements and Wi-Fi

Panasonic just announced a new flagship mirrorless interchangeable-lens camera at the Photokina show in Cologne, Germany. The new Panasonic Lumix DMC-GH3 will replace the Lumix GH2 while adding a new sensor, faster focus speeds, a wider range of video capabilities, and built-in Wi-Fi.

The Lumix GH3 has a new 16-megapixel CMOS sensor and the company's latest Venus processing engine. Panasonic says that the GH3's autofocus speeds are the fastest yet in the G series, at 0.07 of a second. Continuous shooting speeds reach up to 6fps at full resolution, and the GH3 has automated modes for HDR capture, interval shooting, and multi-exposure photos.

Like the GH2 before it, the new camera also has an adjustable touchscreen that can be used for touch-to-focus controls for stills and video. The touchscreen itself is a tilt-and-swivel 610,000-dot OLED display instead of the LCD screen found in the GH2. The new Lumix camera also has an eye-level OLED viewfinder with a resolution of 1.7 million dots.

Video features look to be a major selling point for the new camera, as it captures 1080p video at frame rates of 60p, 30p, and 24p with the ability to perform rack-focus tricks while filming by simply touching different parts of the camera's touchscreen. Like Nikon's newer DSLRs, the GH3 also offers the ability to output uncompressed video to an external monitor via an HDMI connection while filming.

The camera also has a 3.5mm headphone jack for monitoring audio, as well as time code support for professional videographers. Manual exposure controls and ISO settings up to 12,800 are accessible in video mode, and the GH3 also has a range of creative effects that can be applied to both photos and videos while shooting.

On the Wi-Fi sharing front, the GH3 is also compatible with a free "Lumix Link" app for iOS and Android that lets shooters control the camera from a mobile device. Once connected to the camera, a mobile device can be used for remote photo browsing and remote live view, and photos can be geotagged using a mobile phone's GPS data.

There's no official pricing information just yet, but Panasonic says the new camera is expected to cost around $2000. The Lumix DMC-GH3 is due in November.

Canon adds fast lenses and Wi-Fi to high-end PowerShots

The PowerShot G series and S series cameras have long been very popular options in the premium point-and-shoot class, and Canon just announced a few upgrades today that might make them even more enticing for prospective buyers.

Canon PowerShot G15: Fast lens, fast AF, fixed LCD

The PowerShot G15 is the latest model in Canon's bulkier-than-most G series of fixed-lens cameras, and the big addition here is its F1.8 lens. Its predecessor, the PowerShot G12, had a maximum aperture of F2.8 at the wide-angle end, while the G15 has that same F2.8 aperture at the telephoto end of its 5X optical zoom lens (28mm to 140mm).

The PowerShot G15's sensor is the same size as the one found in the PowerShot G12 (both have a 1/1.7-inch-type sensor), and the G15 also has the same Digic 5 image processor as the G12. However, the G15's 12-megapixel sensor itself is a CMOS sensor instead of the G12's 10-megapixel CCD sensor. Canon claims the new sensor is capable of faster continuous shooting speeds (10fps at full resolution), faster autofocus speeds (Canon is claiming 0.17 seconds), and better low-light performance. The G15's maximum ISO setting of 12,800 is two stops greater than the maximum ISO of 3200 found in the G12.

The G15's video-capture specs are also a step up from those found in the 720p-shooting G12, as the new camera captures 1080p clips at 24fps. The PowerShot G15 also has the Super Slow Motion movie mode found in Canon's newer CMOS-sensored PowerShots; the mode records footage at 120fps in 640-by-480 resolution or at 240fps in 320-by-240 resolution.

Strangely missing from the mix is an adjustable LCD screen, which made the G12 and the larger-sensored G1 X fine options for overhead and low-angle shooting. Instead, the G15 has a fixed 3-inch LCD screen as well as a eye-level optical viewfinder above its zoom lens.

Much of the other in-camera features are unchanged. The G15 offers RAW and RAW+JPEG modes, manual exposure controls in addition to aperture- and shutter-priority modes, a range of creative image filters, and a hot shoe for external flashes.

The Canon PowerShot G15 is due in October for $500.

Canon PowerShot S110: Just like the S100, but with Wi-Fi and a touchscreen

With the new PowerShot S110, Canon is standing pat with the F2.0 aperture found in the PowerShot S100, but the S110 has the same new sensor found in the G15. That new sensor purportedly gives it faster autofocus speeds, a 10fps burst mode, and ISO settings that ramp up to 12,800. The PowerShot S110 also has the same 5X optical zoom lens found in the S100, ranging from 24mm wide angle to 120mm telephoto.

The big additions are built-in Wi-Fi and a touchscreen interface, two things that weren't part of the S100's feature set. The Wi-Fi features are built to work with a free Canon CameraWindow app for iOS and Android devices; you can upload images and video to social-networking sites directly from the camera, offload them to a mobile device, or use a smartphone's GPS data to geotag images. Unlike the S100, the S110 doesn't have built-in GPS.

Beyond the new wireless features and the touchscreen UI, this camera is essentially a carbon copy of the PowerShot S100. The S110 has the same click-control ring around the lens for adjusting in-camera settings, RAW and RAW+JPEG shooting, manual exposure controls, and very pocketable size as its predecessor. Unfortunately, battery life hasn't improved, as the PowerShot S110 is rated at 200 shots per charge.

Due in October, the Canon PowerShot S110 is priced at $450.

Ballmer quotes Microsoft Surface pricing: $300 to $800

In the suspense-filled lead-up to the release of its Surface tablets, Microsoft has declined to discuss how much the devices will actually cost--until now, at least. In a Friday interview with The Seattle Times , Microsoft CEO Steve Ballmer hinted at a pricing ballpark: $300 to "$700 or $800," quelling rumors that the Surface RT would sell at the bargain, Kindle Fire-esque price of $199. Also revealed in the interview: The Surface tablets will indeed be sold inside Microsoft's fall-season pop-up stores in malls around the country.

The Times managed to coax the pricing expectations from Ballmer by asking if Microsoft was planning to compete against the iPad on price or on features. The answer, it seems, is features: Ballmer noted that when companies make tablets to be cheaper "they do less. They look less good, they're chintzier, they're cheaper." His example was the original $199 7-inch Kindle Fire, which is anything but a productivity device.

$300 to $800 is "the sweet spot" for the PC market, according to Ballmer. While a $500 spread may seem like a huge range, it's arguably reasonable considering there are two quite different versions of the Surface. The Surface RT should be priced closer to the iPad and Android tablets, while the Surface Pro goes up against Ultrabook laptops.

With most popular 10-inch tablets priced between $449 (e.g., the Samsung Galaxy Tab 2) and $499 (e.g., the 16GB iPad), a $300 starting price for the Surface RT would still be very aggressive—even if it's not the amazingly low price of $199.

A $700 or $800 Surface Pro tablet PC would also be very competitive against current Ultrabook prices. It was only a few months ago that Lenovo broke the $800 Ultrabooks price barrier. The Surface Pro also has a lot going for it: a super-thin 0.53 inch thickness (compared to many Ultrabooks measuring about 0.8 inches thick) and about half the weight of competing 4-pound Ultrabooks. You'll have to make due with the tablet's small 10.6-inch HD display for that ultraportability, but you'll get the full computing power of a laptop with detachable keyboard cover.

The line between tablet and laptop is definitely blurring, Ballmer pointed out in the interview. Windows 8, with its touchscreen capabilities, is a major driving force behind the many hybrid PCs about to flood the market.

Microsoft Surface RT tablets are due to take on the tablet and laptop competition on October 26 and the Surface Pro 90 days after that.

U.S. Tops World in Music Pirate Downloads

Americans downloaded some 96.7 million music files from the BitTorrent file sharing network during the first half of the year, according to a report from Musicmetric, an online music analytics firm.

BitTorrent contains both legal and illegal files, but most of the music downloads identified in the study are not legally available on the network, Musicmetric said in a statement.

The United States topped all nations in unauthorized music downloads during the period, Musicmetric reported, followed by the United Kingdom (43.3 million), Italy (33.2 million), Canada (24 million) and Brazil (19.7 million).

There was both good news and bad news in the report for the music industry. The good news was that for the first time since 2004, record companies' digital music revenue growth in 2011 increased over the previous year, to eight percent, compared to five percent in 2010.

The bad news is that efforts to cripple one of the largest illegal download sites on the Web, Pirate Bay, hasn't had much effect on the illegal downloading scene. "For the first time, we have evidence that blocking Pirate Bay had little effect on BitTorrent downloading," Musicmetric CEO Gregory Mead said in a statement.

"It is also clear however, that availability of streaming services like Spotify does reduce this activity as people have greater access to music they want via legitimate means," he added.

In its report, which Musicmetric touted as the most in-depth study ever done on the global digital music landscape, the metricticians maintained that there is a demand for legal downloads that has been untapped on BitTorrent.

The U.S. tops the charts for BitTorrent downloads according to research by online music analytics firm Musicmetric.

As an example of that, they cited the success of The Cardigan EP by Billy Van. That tune, which is licensed for distribution via BitTorrent, is the number one torrent in five of the top 20 download nations. "It has become hugely popular in place of other illegal content in a quarter of the top 20 countries for downloads," the report noted.

While finding ways to monetize file sharing will be challenging, Mead acknowledged, it will be worthwhile for rights holders to do so. "The potential for converting revenue lost through file trading is not entirely a fairy tale, however it will differ with different genres and life stages of [an] artist," he said.

Added BitTorrent Executive Director Matt Mason: "It's short-sighted to think that we can simply tell people to stop and they will."

"The challenge is building the right business models on top of the technology, which is something we're very committed to here," he said.

Over the last two years, rights holders have done more than just "tell people to stop." They've sued some 200,000 BitTorrent users for pirating the rights holders intellectual property.

Judging from the volume of BitTorrent traffic reported by Musicmetric, those lawsuits don't seem to have made much of a dent in file-sharing traffic. What's more, they may not be very economical either. In 2007, for example, the Recording Industry Association of America (RIAA) spent $17.6 million on lawyers chasing infringers only to recover $391,000 for its efforts.

Samsung Galaxy S IV tipped for February 2013, says report

Samsung is looking to derail sales of the iPhone 5 by launching a new Galaxy smartphone just nine months after the Galaxy S III, according to unnamed company officials quoted by The Korea Times. The phone would feature an even larger display at around 5 inches, and is expected to be announced during the Mobile World Congress expo in Barcelona in February next year, hitting shelves a month later.

The Samsung Galaxy S IV would increase the display size to 5-inch, up from the 4.8-inch display on the S III, topping the 4.3-inch display on the S II, which in turn was bigger than the 4-inch display on the original Galaxy S. Samsung already sells the Galaxy Note II with a 5.5-inch display. With the iPhone 5, Apple increased the iPhone display size for the first time from 3.5-inch to 4-inch.

Speculation over the announcement comes days after Apple unveiled the iPhone 5 and pre-orders of the device reached 2 million in the first 24 hours of availability – twice the number the iPhone 4S achieved last year. "iPhone 5 pre-orders have shattered the previous record held by iPhone 4S and the customer response to iPhone 5 has been phenomenal," said Philip Schiller, Apple's senior vice president of Worldwide Marketing. Pre-orders also skyrocketed over the weekend too, as AT&T said the iPhone 5 is "the fastest-selling iPhone the company has ever offered." The first iPhone pre-orders should arrive on September 21.

Since the iPhone 5 was announced, Samsung has promoted heavily its Galaxy S III. First, Samsung began to run a newspaper ad strangely comparing the S III to the iPhone 5. Now, if the Korea Times report is accurate, Samsung is looking to make the S III obsolete by launching the Galaxy S IV only nine months after its predecessor. Sales of the Galaxy S III have reached more than 20 million worldwide in three three months to September, and Samsung said it expects this to rise to 30 million by the end of the year.

What do hard drive-related words like SATA, IDE, and RAID actually mean?

Brainout asked the Hard Drives, NAS Drives, Storage forum to explain some of the words used to describe hard drives and storage.

Technical terms can get overwhelming, especially when they include too many TLAs (three-letter acronyms). Even people who use these terms sometimes need to step back and remember what they're talking about.

So here are some of the most common labels for the technologies used to store data inside your computer:

HDD: Hard disk drive. A magnetic, mechanical device that's been the primary internal storage device for more than a quarter century.

Flash RAM: Silicon chips that, unlike other types of RAM, can hold data without an electric current--a feature that makes them useful for storage. (RAM stands for Random Access Memory.)

SSD: Solid state drive. Flash memory packaged in an HDD-like form factor, to be used in place of a hard drive. SSDs are generally faster than HDDs, use less power, and are less likely to be damaged by a fall or shock. They also cost much more per gigabyte.

Partition: A section of a hard drive (or SSD) that appears to the operating system as a separate, independent drive. People use multiple partitions to run more than one operating system, or to separate programs from data. Most major-name Windows PCs come with a special recovery partition containing the files needed to restore Windows.

SATA: Serial Advanced Technology Attachment. The current standard technology for connecting a hard drive or SSD to the rest of the computer.

IDE: Integrated Drive Electronics. The older standard that SATA replaced.

RAID: Redundant Array of Independent Disks. Two or more drives working together to enhance performance or redundancy. For instance, in a RAID 0, two drives work as one larger and faster drive--faster because twice as many drive heads are reading data simultaneously. In a RAID 2, two drives contain the exact same files, so that if one dies the other continues to work. Other configurations allow both speed and redundancy.

Google adds 'Do Not Track' to Chrome by year's end

Editor's Note: The following article is reprinted from Computerworld. The original version of this story can found here.

Google has moved a step closer to making good on its promise to support "Do Not Track" in Chrome by the end of this year.

Chromium, Google's open-source project that feeds code into Chrome, released a build last week that includes the Do Not Track (DNT) privacy setting.

It's unclear how quickly the setting will be moved to the multi-channel build structure of Chrome itself. Google maintains three versions of Chrome: Dev, Beta and Stable, each succeeding version more polished than the last.

The Stable branch of Chrome is due for an upgrade: Google last updated the browser on July 30, when it shipped Chrome 21. The company usually upgrades Chrome every six to eight weeks, putting Chrome 22 on the horizon and Chrome 23, which is now in the Dev channel, up for delivery sometime in November.

In February, Google said it would add DNT support to Chrome after the White House said it would introduce new online privacy legislation in Congress.

Chrome joined other browsers, including Microsoft's Internet Explorer, Mozilla's Firefox and Apple's Safari, that already transmitted special information with every HTTP page request to tell sites the user does not want to be tracked by online advertisers.

Then, Google promised to add DNT to Chrome by the end of the year, but declined to spell out a time or describe how the browser would present the option to users. Google was the last major browser maker to commit to DNT.

In Chromium "23.0.1266.0 build 156627" or later, the DNT setting appears under the "Privacy" section of the browser's Settings screen.

To pull up the Privacy section, users must first click the "Show advanced settings..." link at the bottom of the page. Checking the box marked "Send a 'Do Not Track' request with your browsing traffic" switches on the privacy feature.

Jonathan Mayer, a graduate student in computer science and law at Stanford University, and one of two researchers at Stanford who created the HTTP header concept to signal a user's DNT preference, bemoaned the placement of the setting in Chromium.

Chromium puts the 'Do Not Track' setting under the Privacy section of its Settings screen. Expect Chrome to do the same.

"Good: looks like Do Not Track will be in the Chrome privacy preferences. Less good: have to click 'Show advanced settings...' to see them," Mayer wrote on Twitter last Thursday.

Chrome places the Privacy section of Settings in the same location, however.

Although browsers have, or will, implement DNT on their end, the crux is websites, which must enable it on their ends. Twitter is the largest online service, by far, to have implemented DNT.

A group composed of advertisers, browser makers, privacy advocates and others have yet to finalize the DNT standard. The Worldwide Web Consortium (W3C) standards-setting group has, however, decided that browser makers cannot set the DNT signal for users.

But a move by Microsoft has roiled the group.

In May, Microsoft announced that Internet Explorer 10 (IE10) would enable DNT by default. During Windows 8 setup, for example, DNT is automatically turned on if users accept the default settings offered during the operating system's setup. They can, however, switch it off during that setup process, or at any later time.

Google has said little publicly, but by the way it presents DNT in Chromium, it looks to be firmly in the off-by-default camp. Apple's Safari also leaves its DNT option unchecked.

Since May, members of the W3C group have debated whether websites should be required to honor IE10's on-by-default signal.

The controversy over IE10 and DNT was stirred again two weeks ago when developers of the Apache Web server software added a patch to ignore the DNT header when it is sent by IE10. According to U.K.-based Netcraft, Apache powers 55% of all active websites worldwide.

Users can download the most-recent Chromium build from this website.

Two new Olympus PEN cameras put OM-D sensors in pocketable bodies

The Olympus PEN E-PL5 has a tilting touchscreen LCD.

Olympus's OM-D E-M5 is one of the best mirrorless interchangeable-lens cameras we've reviewed in the past year, but it's practically the size of a full-on DSLR. If you're looking for the same kind of imaging capabilities in a more-compact camera, one of two new Olympus PEN models announced Monday might do the trick.

The Olympus PEN Lite E-PL5 is the higher-end of the two new interchangeable-lens cameras. The PEN E-PL5 has a physical mode dial, a tilting 3-inch touchscreen that can be adjusted up and down, and a removable screw-on handgrip. Those are three features that distinguish it from the lower-end Olympus PEN Mini E-PM2, which has no mode dial, a fixed touchscreen, and a built-in handgrip.

Both cameras offer the same 16-megapixel sensor and TruePic 6 image processor found in Olympus's flagship OM-D E-M5 mirrorless camera, but in much more compact bodies. At 4.3 inches wide, 2.5 inches tall, and 1.5 inches deep, the E-PL5 can fit in a jacket pocket with a pancake lens attached. The PEN E-PM2 is even thinner, measuring 1.3 inches deep.

The new cameras also boast extremely fast autofocus speeds, which is put to good use in each camera's "Touch AF" feature; you can simply touch subjects on the screen when framing photos or videos to have the autofocus system lock in immediately. In some brief hands-on time with each new model, the cameras were able to focus on a subject and capture an image within a fraction of a second of touching the LCD. That's a good feature for action shooters, as are the cameras' 8fps burst modes at full 16-megapixel resolution with focus and exposure locked at the first shot.

The PEN Mini E-PM2 lacks a mode dial and a tilting LCD.

Each camera lacks a built-in flash, but both come with an external flash that mounts onto the top-mounted hot shoe. The E-PL5 and E-PM2 have ISO settings that reach up to 25,600, 1080p video recording at 30fps, full manual exposure controls in addition to aperture- and shutter-priority modes, and RAW and RAW+JPEG shooting modes.

The new PEN cameras also have several bracketing modes with adjustable settings, including an exposure-bracketing setting, ISO bracketing, and flash-intensity bracketing. In addition to the full library of creative effects found in previous PEN cameras (which Olympus calls "Art Filters"), there's a new watercolor painting effect in the mix, as well.

Like the latest interchangeable-lens cameras from Samsung and Sony, the new Olympus PENs also feature a companion mobile app for sharing images and video directly to a mobile device, but the cameras don't have Wi-Fi capabilities built into the camera. Instead, the E-PL5 and E-PM2 have an interface that's optimized for use with Toshiba's FlashAir cards, which are separately sold SD cards with Wi-Fi connectivity. When used with a FlashAir card, the new cameras will allow shooters to offload images and video to mobile devices by using a free "Olympus Image Share" app for iOS and Android.

15mm/F8.0 lens.

Both cameras are due in October. The PEN E-PL5 will cost $650 for the body only or $700 as a kit with a standard 14-42mm zoom lens. The PEN E-PM2 will cost $550 for the body only or $600 as a kit with the same lens. The Olympus PEN series has a focal length multiplier of 2X.

60mm/F2.8 lens.

Two new lenses for the PEN series were also announced today, including an extremely compact lens that doubles as a lens cap for the camera. A new 15mm/F8.0 prime lens is built for street shooting in daylight, and it's small and light enough to make each camera feel more like a point-and-shoot than an interchangeable lens camera. It has a lever on the side of the lens that operates a sliding lens cover, which is why Olympus is billing it as a lens/cover combo. The second new lens is a more-traditional ; given that maximum aperture, it should be way more forgiving in low-light situations than the new pancake lens.
