    Sony has unveiled the RX100 VI 20.1-megapixel premium compact camera with a new telephoto lens that will make it a lot more interesting for travel photography. Rather than the Zeiss Vario-Sonnar 24-70mm equivalent f/1.8-2.8 T lens of the last model, the Mark VI packs a hugely longer, optically stabilized 24-200 f/2.8-4.5 T mm 8.3X zoom lens. That's over a stop slower than previous f/1.8-2.8 T lens, but the extra range will be worth it for many folks, and Sony has boosted other specs to make up for it.

  • Sony's A7 II camera gets a faster and more accurate autofocus

    The Sony A7 II is one of the best mirrorless cameras available right now, although it isn't perfect. After trying it out earlier this year, one of our main issues with the full-frame shooter was its autofocus performance, which was at times slow and unreliable. But Sony has an update coming soon that, along with bringing a new feature, promises to fix some of these woes. In addition to activating the phase detection AF on the A7 II, the company's also turning on support for uncompressed 14-bit RAW image capture -- something that already exists in models such as the A7S II, A7R II and RX1R II. You can grab the refreshed firmware, version 2.0, on November 18th from Sony's support website.

  • Sony's new sensor could bring DSLR-like autofocus to phones

    While there's speculation that multi-sensor phone cameras are the next big thing, Sony has just launched a sensor that will likely make its smartphone cameras better soon. The latest Exmor RS IMX230 is a so-called stacked CMOS sensor that squeezes an effective 21-megapixels into a 1/2.4-inch sized form factor. The killer feature, however, is built-in 192-point phase-detection autofocus, which will keep fast-moving subjects sharp. The new chip also has integrated HDR for high-res stills and 4K video to save shots that are overly backlit or in shadow (see the image below).

  • Canon's EOS C100 Cinema camera to get continuous autofocusing through $500 upgrade

    Movie makers thrive on quick autofocusing for their action shots, so they'll be glad to hear that Canon will offer an upgrade to the EOS C100 video camera with that kind of performance in mind. The $500 transplant will give the C100 continuous autofocusing using a variant of the extra-fast Dual Pixel CMOS AF technology found in the EOS 70D. Owners will also get AF lock controls, focus presets and much speedier center-only focusing. Don't rush to plan your next big video project around the upgrade, though. Canon doesn't start upgrading the C100 until February, and you'll have to send your $8,000 camera to a service center for the (comparatively cheap) overhaul.

    Despite the raves that recent micro four-thirds and Sony E-Mount cameras have received of late, there's still a dearth of lenses for the fledgeling systems compared to their more entrenched counterparts. Luckily, Sigma's just added to the pool of autofocus-equipped models for each system: updated 19mm F2.8 DN and 30mm F2.8 DN models along with an all-new 60mm F2.8 DN telephoto lens. Each Japan-made model has a "telecentric" optical design to minimize CMOS color issues, a metal exterior with silver or black color options, and a linear autofocus motor that Sigma claims is quiet enough to use for video. Meanwhile, the imaging outfit also announced an updated 30mm, F1.4 DC HSM model for Canon APS-C, Nikon DX and its own Sigma mount. All that's great news, though we're still waiting for an AF/electronic F1.4 or faster lens for E-Mount (there's only one on MFT as well) -- though this might tide us over, in the meantime.

    Just as Fujifilm is getting under way with its CES 2013 press conference, the folks over at FujiRumors found some footage of Fujifilm's new digital split image display from the newly announced X100s. Earlier this week, the company announced this new way of manual focusing on the X100s, in which the user overlays two images to attain proper focus. This feature seems to hit a high note for range finder camera users as it brings a certain familiarity for focusing work flow. Note that the display in the video is the rear LCD of the camera and not the prized hybrid viewfinder. Overall the movement looks smooth and usable, but we'll confirm when we get our hands on the new X100s. Check out the video after the break. Follow all the latest CES 2013 news at our event hub.

  • OmniVision unveils 5MP BSI sensor that takes low light cameras further into the entry level

    It's almost a truism that starter smartphones have poor cameras that struggle just to get pristine photos in broad daylight, let alone dim interiors. Thankfully, OmniVision's new OV5645 sensor could lead newcomers out of a very literal darkness. The 5-megapixel imager includes backside illumination, support for 1080p30 (or 720p60) video and its own internal autofocus system, but no dedicated JPEG compression engine -- in short, a lot of the low-light performance of more sophisticated smartphones without the usual attached costs. Its cost-cutting even extends to front cameras, as a forward-facing sensor can share resources with the back camera to scale back on redundant hardware. We're looking forward to when mass production starts in the first quarter of 2013; we might not have to excuse our photo quality for a long, long time afterwards.

    Canon USA has just released a new firmware update for its professional EOS-1D X camera that expands the capabilities of its autofocus point illumination. It will now support AI Servo AF as well as cross-type AF at apertures as small as f/8. The former is especially welcome in low-light situations like weddings and theatrical performances, while the latter would benefit those who use EF super-telephoto lenses with extenders, like wildlife photographers for example. In fact, you can check out the now-wider range of compatible EF lens/extender combinations at the source. Those interested in the update can download it now for free from Canon's website.

  • Nikon confirms woes with D4 and D800, joins Canon in high-end doghouse

    Okay Nikon owners, stop laughing at your 5D Mark III cronies for their leaky problem. That might be a drip in the pail next to your own worries -- namely, possible "lock-up", focus and viewfinder hitches on your D800 or D4. Nikon verified that a "small number" of units of both DSLRs can lock up and become unresponsive, but until there's a permanent patch you can prevent this by disabling both highlight and RGB histogram displays. The company also verified that a "run" of D800s is suffering from a viewfinder bug, although it has yet to confirm another emerging problem with autofocus in some units, which apparently requires a factory fix. So, if you've noticed any of this with your pricey new D800, or really pricey D4, your best bet might be to reach out to your Nikon repair center post-haste. And don't let the Canon guys see you. [Thanks, Thinh]

    It's no secret that Sony's A77 and A65 SLT cameras have suffered from noticeable lag when it comes to adjusting exposure settings, among other things. For those irked, you'll be pleased to know that the company has just updated both cameras to firmware version 1.05, claiming it'll "sharpen their responses." Specifically, you'll be noticing faster cold startups shutdowns, quicker response times from the front and rear dials and faster access to images in auto review. That's not all, however, as Sony has also added in-camera shading and chromatic aberration compensation for 11 of its A-mount lenses, which can translate to less time cooking your images in post. Last, but not least, the A77 gets an extra bonus for its autofocus system that improves its abilities in high-contrast environments, while the SAL500F40G 500mm F4 G SSM super-telephoto lens will now focus faster with both shooters. Shutter finger already twitching? Don't delay, you'll find full details in the press release after the break and download information at the source link below.

    Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. Is learning how to meter with your camera really necessary? With all the intelligent models out today, who needs it, right? Well, you may, depending on the type of killer photography you hope to produce. When it comes to the person behind the camera, there are a few types of photographers. First, there's the photog who just wants to snap away, not terribly concerned about how their photos turn out -- or, at the very least, not interested in knowing how to alter the camera. If this describes you, that's fine -- the latest-and-greatest compact cameras may be your cup of tea. But then there's the amateur shooter who desires a better understanding of how their cameras determine exposure, and if you fit into this category, this piece should be right up your alley.Metering is not a subject you can easily master, let alone explain entirely in an article of this length, but we can give you an idea of how it all works. I consistently see the faces of my workshop students glaze over as I wax rhapsodic about the wonders of metering, but I also notice wry smiles from time to time, which shows me the wheels are turning -- they begin to realize all the things they can do if only they can conquer this aspect of photography. However, comprehension and applied mastery are two separate balls of wax. Putting what you learn to practice is the start, and you can improve over a number of months, but true metering control in any situation requires years of practice.So for our 2012 pre-apocalyptic installment of Primed, we'll break down the world of camera metering, giving you a bit of history, dissecting the main components, describing what your camera wants to do and telling you what the future may hold. By the end, you'll have a better understanding of this vital photographic topic... either that or you'll be in a nice deep sleep.Note: Check out our recent Primed articles on aperture and image sensors to add to your metering knowledge.

  • Is this Nikon's D800 DSLR?

    Grab the salt shaker folks -- if Nikon Rumors is to be believed, what you're gazing at is Nikon's hotly rumored D800 DSLR. The camera is reportedly packing goodies like a massive 36 megapixel sensor capable of 7360 × 4912 resolution, and an ISO range of 100 to 6,400 that's pushable to 25,600. Furthermore, you can expect to find the same 51-point AF system found in the D3s, slots for SD and CF cards, USB 3.0 connectivity and over three-inches of display on back -- all while being "smaller and lighter" than the current D700. Notably, Nikon is apparently stepping up its DSLR video chops with this cam as well, as it's said to be capable of filming 1080p HD video at 30 fps, while 720p grants you up to 60 fps. Of course, this type of primo kit won't come cheap -- if it all proves true you can expect to slap down roughly $3,900 (¥300,000) to make one yours, although, a release date is still anyone's guess. You'll find another shot of this purported beauty after the break and the full rumor rundown at the source link below.

    Hey Sony, you hear that? Sounds like you might have another leak on your hands. We got our fourth unofficial look at Sony's Alpha A77 this morning, and now it's time for a little accessorizing. What you see above is reportedly a shot of a new lens adapter called the LA-EA2, which would apparently bring the outfit's translucent mirror technology to its range of little NEX shooters. As you might recall, that mini-mirror brings with it continuous phase-detect autofocus. Of course, this is just a rumor, but it does lines up with previous reports of a forthcoming NEX-7. You know we enjoy a leak as much as the next guy, but we like hard facts even more. So what's it going to be Sony?

  • Nokia claims N9 is 'the fastest image-capturing phone' yet

    We've already established that the N9 is a delight of a phone, both inside and out, but our hands-on time with Nokia's new flagship gave us only a brief look at its camera performance. Now the company is graciously filling that gap in our knowledge with some further disclosure about its new 8 megapixel imager, including the lofty claim that the N9 is the fastest phone yet when it comes to capturing an image -- ousting the likes of the iPhone 4, the Galaxy S II, and even the Canon S95, perhaps the best pocket camera around at the moment. Measuring the time taken from activating the camera app to the completion of the first shot, the N9 clocks in at 2.6 seconds, whereas Apple's latest does it in 3 seconds and Samsung's takes a split second more. Aside from its speed, the N9 has Carl Zeiss optics, a wide F2.2 max aperture, dual-LED flash, continuous autofocus, and a 720/30p video mode to boast about, but the benefits of those items will need to be experienced first hand. So Nokia, when are you shipping this thing?

  • Pantech Crossover review

    Time to ditch the pull-ups, because Pantech's a big kid now. It's hard to fathom that the company responsible for hits like the Zoolander-ish C300, Helio Ocean and dual-sliding Duo is only now -- after five long years -- taking a chance at the Android market in the US. Certainly its long-time partnership with AT&T is finally looking to pay off in a big way, as the network introduces the appropriately-named Crossover. The carrier's been starving for a decent physical QWERTY to add to its (fortunately) blooming Android lineup, so seeing Pantech step up to the plate and fill the void should come as a huge relief. Though it's serving up monoliths in Korea that feature 1.5GHz dual-core processors and other outlandish specs, Pantech looks to be starting its stateside tour with a less-risky investment: at $70 with a 2-year agreement, its modest first impression appears targeted toward first-time smartphone buyers. Is it worth dropping a Grant and a Jackson to adopt the Pantech Crossover for the next two years? Read on to find out.

    We're not the only site to put Nikon's new mid-range DSLR through its paces. Plenty of others have taken the D5100 for a spin and we thought you might like to know: they're all pretty impressed. The new 1080p30 video mode was much appreciated as was the larger, higher resolution swivel screen around back. The biggest props generally went to the improved high-ISO performance (which was already quite respectable on the D5000 it's replacing) and the boost in autofocus speed, especially when using the LCD as a view finder in Live View mode. Oddly, the built-in effects also garnered a lot of attention. The Miniature Effect (a tilt-shift simulator) and Selective Color mode impressed reviewers the most with their surprising level of sophistication for in-camera processing. All of the effects can also be used when shooting video, so you can make your HD footage look like black and white 8mm by turning on Night Vision. Criticisms were relatively minor and applicable to most mid- and entry-level DSLRs -- primarily that the body is plasticy and there is a slight lag in focus and shutter performance. The D5100 is an obvious upgrade over the D5000 and more than holds its own against its competitors, but if you want to dig deeper check out our review and the ones below.

  • Sony NEX-5 and NEX-3 firmware update adds autofocus support for company's A-mount lenses

    Sony has taken the time to upgrade the firmware on its minuscule NEX-5/3 system cameras to improve usability, make manual focusing easier, and allow single-shot autofocus when using A-mount glass via an adapter. The latter will be perhaps the most important thing for owners of Sony's large-sensor compact, allowing them to use a total of 14 lenses from the company's DSLR range without having to worry about focusing manually. Though, if you are into that kind of thing, the MF Assist mode has been improved with a new feature giving you a zoomed-in view of the area you're trying to keep sharp -- to make it easier to tell if you're doing it right. The UI has also undergone a bit of a streamlining, which you can check out for yourself by downloading the new software from the source link below.

  • Nikon D3100 DSLR hands-on

    In addition to the S1100pj and S5100, we also had a chance to play with Nikon's 14.2 megapixel D3100 earlier today. Sadly, due to the non-final firmware, we weren't allowed to obtain live sample stills and 1080p H.264 clips from the prototype DSLR, so we can't comment too much on the new CMOS sensor's picture quality. Still, there were some interesting features to point out here. Most notably, the seemingly solid D3100 has an improved grip compared to its predecessor and our own D5000 -- it certainly felt nice and secure in our hands despite the small (and slightly lighter) body. We also dig the new switch (resting by the now-larger dial) for quickly toggling various shooting modes, along with the new spring-loaded live-view trigger and video recording button (both at the top-right corner of the 3-inch 460k-dot screen). Of course, we couldn't have gone home without having tested the video mode's headlining continuous autofocus feature -- we weren't able to tell how much motor noise might have gone into the clips, but the bundled 18-55mm lens was able to autofocus or track subjects at reasonable speeds, provided that we weren't zooming or moving about too rapidly. The only real bug we noticed was that sometimes the tracking may get overridden by large nearby objects with similar colors, so hopefully the final firmware will reduce this error. Another concern is with the new 1,030mAh battery -- no word on how many shots or video hours it can provide, but we shall find out when this $699 DSLR comes out next month.%Gallery-99892%

    We had a feeling we'd be seeing the well-leaked Nikon D3100 this week after the Coolpix S1100pj and S5100 were officially launched on Tuesday, and here it is, right on cue. Just as we'd heard, the big news is the addition of a 1080p/24 H.264 AVCHD movie mode with continuous contrast-detect autofocus, complete with face detection and subject tracking. That's a major first in the DSLR world, although we're extremely curious to hear how much focus motor noise you can hear in the clips -- we've definitely had issues with other continuous autofocus systems in the past. That new focus system carries over to regular Live View and the 720p movie mode, which shoots at both 24 and 30fps, and the new 14.2 megapixel sensor can be boosted from its native max of ISO 3200 up to 12,800 for some low-light action. Around back there's a three-inch screen, and Nikon's also beefed up the Guide mode, which the company says was extremely popular on the D3000 -- it shows you how to use the various features of the camera, complete with comparison shots showing the effects of different settings. The D3100 will run $699 with the usual 18-55mm VR kit lens when it hits in September -- we've got grand plans to put that video AF system through the wringer when we get one, but for now check some pics in the gallery and PR after the break. %Gallery-99799%

    "Fixes a phenomenon in which the set aperture moves when shooting movies in manual exposure mode using some Canon lenses (such as macro lenses)." If you've got a 5D Mark II, 1D Mark IV, or Rebel T2i handy and have been keeping its firmware fresh, that phrase should be all too familiar; all three of those shooters have received updates in the past two months to fix such an issue, and now it's time for the EOS 7D to get a fix all its own. Our darling budding filmmakers' tool is also getting a few tweaks with AF point display and selection, and the multilingual copy editors of this world can breathe a deep sigh of relief as typos in the Spanish and Thai menus have been corrected. Well, what are you waiting for? Focus your lens on Canon's website and download away.
