Sigma unveils three new MFT and Sony E-Mount lenses
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.

Engadget Primed: Camera metering explained
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.
Sony LA-EA2 lens adapter gets ready for its close-up in 'leaked' render
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?
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.
Canon EOS 7D joins fleet in receiving firmware update to fix manual exposure movie bug
"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.
WoW Moviewatch: Darkwinds Scourge
The Darkwinds Scourge is a roleplay Guild on the Sha'tar realm. They've created this machinima as a kind of trailer for their Guild. In terms of setting up a movie to help promote your Guild's themes and ideas, I think this works pretty well. The shot locations are spot on, and the music's totally appropriate. (The song is by Disturbed, I think.) The movie is credited to Almighty Farseer.As a machinima, the visiual narrative could use a faster pace. The author's stuck in the loop of cool shot after cool shot. Individually, they all work well, but strung together, the scenes move a little slow. While AF says that the Guild is an evil-themed troupe, with the in-character goal of punishing "the traitor Darion Mograine," I'm not sure there's enough contextually in the movie itself to draw that conclusion. Some subtitles or screen overlays would help that immensely, and help draw the viewer into the story.Still, it's a trailer piece for a Guild, and on that level, it works fantastically. It would be nice to see more Guilds put this kind of effort into branding themselves, and I look forward to more in this genre.If you have any suggestions for WoW Moviewatch, you can mail them to us at machinima AT wowinsider DOT com.Previously on Moviewatch ..
Canon brewing yet another autofocus fix for EOS-1D Mark III?
Unfortunately, details are extraordinarily scant at the moment, but it appears that Canon is readying one more fix for the EOS-1D Mark III, which has been plagued with an autofocus issue for what seems like ages. Apparently, the forthcoming fix -- which could involve hardware and / or firmware alterations -- will make improvements even over last year's tweak. Reportedly, the firm's AF engineers are confident that they have now realized the "root cause" of the problem, hinting that this solution may in fact be the last. Per usual, there's been no clues handed out as to when users will actually be notified that a fix is available, but we're sure official word will stream out soon enough if there's anything to this.
Canon's EOS-1D Mark III autofocus fix makes strides, stops short
Remember that autofocus fix that Canon was supposedly working up? Turns out, the company isn't quite ready to start accepting faulty EOS-1D Mark IIIs just yet, but it is shipping out upgraded versions to new buyers. Rob Galbraith managed to wrap his hands around not one, but three of the new DSLRs in order to substantiate his findings, and what he found was noticeable improvement. In summary, the sub-mirror fix was said to boost the performance of the AF, as it enabled the camera to deliver "about the same number of in-focus frames whether it was warm or cold." Unfortunately, it seems that the solution still left a lot to be desired; Mr. Galbraith noted that it still couldn't match the EOS-1D Mark II N, and implied that there was still room for betterment. 'Course, we're really just scratching the surface on his thorough (and we mean thorough) look at the sub-mirror fix and v1.1.3 firmware, so if this issue has been hounding you, do yourself a favor and check out the read link.[Thanks, Anand]
Canon planning fix for EOS-1D Mark III autofocus issue
If you're one of those folks who just refused to fork out thousands of dollars for an EOS-1D Mark III after hearing reports of a seemingly widespread autofocus issue, take heart. Apparently, Canon is fessing up to the problem and is planning a remedy, although a simple firmware update doesn't seem to be it. According to an interview with Chuck Westfall, Canon USA's Director of Media and Customer Relationship, the firm is looking to issue a hardware fix that "adjusts the sub-mirror within the body." The company doesn't seem to think that every one of these beasts are afflicted, and its supposedly gearing up to provide a "simple way for owners to identify if their camera is among those affected." As for dates, US-based owners should be hearing more details about how the process will work by "the end of this month," while buyers that reside elsewhere will likely be informed shortly thereafter.
