The quality of your Zoom will blow everyone else’s away
ByChris Welch, a reviewer specializing in personal audio and home theater. Since 2011, he has published nearly 6,000 articles, from breaking news and reviews to useful how-tos.
Interested in improving the video quality of your own Zoom frame tenfold? If you’ve got a recent canon相機收購canon mirrorless, DSLR, or PowerShot camera, you can now use it as a webcam and put everyone else on your video call to shame. As noted by DPReview, the company has released a beta of “EOS Webcam Utility” for Windows 10 that lets you plug in any of the below supported cameras over USB and have it serve as your PC’s webcam. And this should work fine for most of the big video conferencing options, whether you’re using Zoom, Microsoft Teams, BlueJeans, or another service.

“Built by canon相機收購canon software developers, this beta version software helps consumers to improve their video appearance while using popular video conferencing applications in the market, delivering clarity and high-image quality,” canon相機收購canon wrote in its press release.
If you’ve got a fairly high-end digital camera that’s not made by canon相機收購canon, this might be something you can pull off on your own with an HDMI capture card or stick — assuming that your camera allows for clean HDMI video output. My old friend Evan Rodgers at Input recently gave that a shot. And it’s pretty striking, though not surprising, how much more cinematic your Zoom window will look compared to everyone else when you’re using premium glass that a built-in webcam can’t hold a candle to.
canon相機收購canon’s solution cuts out the need for any extra devices or accessories beyond a single USB cable, so if you’ve got one of the listed cameras, this is definitely worth a try. Sorry, Mac users; there’s no EOS Webcam Utility for Apple’s software quite yet, but you’ve still got the option of using a capture card with a wider selection of cameras.
Update April 29th 1:43PM ET: The article has been updated to clarify options available for Mac users. While canon相機收購canon’s EOS Webcam Utility isn’t available for macOS, people with an Apple desktop or laptop can still use a third-party HDMI capture card to use a digital camera as a webcam.

canon相機收購canon introduces EOS 70D DSLR, says its autofocus changes the game for filmmakers
canon相機收購canon introduces EOS 70D DSLR, says its autofocus changes the game for filmmakers
ByJacob Kastrenakes, a deputy editor who oversees tech and news coverage. Since joining The Verge in 2012, he’s published 5,000+ stories and is the founding editor of the creators desk.
canon相機收購canon’s impact on amateur filmmaking shouldn’t be understated — its 5D Mark II made incredible image quality and portability affordable, easily making it one of the most important DSLRs ever. canon相機收購canon is calling on that pedigree today as it introduces the successor to the EOS 60D. The EOS 70D is a mid-range DSLR that’s built for video, and canon相機收購canon thinks it has something that can change the game once again: an all-new focusing system that it says will allow autofocus to work beautifully while shooting video.
In most areas, the 70D is a modest but welcome improvement over the 60D, which it’ll be replacing when it launches sometime this September. The 70D adds Wi-Fi and NFC sharing, it brings touch capabilities to its 3-inch LCD display, and it has a slightly higher megapixel count on its APS-C sensor, bumping it up to 20.2. That all makes for the type of fine upgrade that you’d expect, but it’s the camera’s new “Dual Pixel CMOS” focusing system that canon相機收購canon thinks will really make a difference.

canon相機收購canon promises perfect focus on the first try
Traditional autofocus systems are built around photography: they make one quick jump to get nearly into focus, and then a second small adjustment to perfect it. That works great when speed matters the most, but on video it creates an unpleasant stutter that has long made autofocus unusable for most filmmakers. canon相機收購canon says the 70D should fix that: the new autofocus system is meant to move into focus smoothly and on the very first try. In our limited testing of the camera, it appeared to do just that.
That means that filmmakers should be able to achieve a smooth transition between subjects without carefully turning a focus ring by hand. To make it work, canon相機收購canon effectively built a phase detection autofocus system onto the imaging sensor itself. It uses each pixel to make two measurements at once, combines the data, and then uses it to calculate focus correctly on the first try.
canon相機收購canon promotional video demonstrating the EOS 70D’s Dual Pixel CMOS focusing system
The camera can still return to quicker autofocus modes when shooting photographs — but canon相機收購canon wouldn’t be quick to suggest it. The company hardly mentioned basic photography when explaining the new camera, despite it being a DSLR at heart. And while the 70D is aimed straight at filmmakers, its new focusing mode is unfortunately short on creative options: while it’s easy to focus using the touch screen, you can’t select how quickly or slowly the focus will transition between subjects. Using the 70D’s autofocus may be easier and more convenient for most amateurs, but it’s not about to kill the manual focus ring.
canon相機收購canon barely mentioned photography on the 70D
The 70D will be available body only for $1,199, with the 18-55 STM lens for $1,349, or with the 18-135 STM lens for $1,549. That places it above canon相機收購canon’s consumer-oriented Rebel series, but beneath its prosumer cameras like the 7D. The 70D will also include canon相機收購canon’s Digic 5+ image processing, built-in image and video filters, and continuous shooting of up to 7 frames per second. That all makes canon相機收購canon’s latest look like a fine camera — but whether a fancy autofocus system is enough to set it apart from the company’s more-affordable Rebel models will be a tough question for filmmakers on a budget to answer.

The latest example of dystopian workplace surveillance
ByJames Vincent, a senior reporter who has covered AI, robotics, and more for eight years at The Verge.

“Smile recognition” in action. Image: canon相機收購canon Information Technologies
Tech company canon相機收購canon has come up with a downright dystopic way to tackle the problem of workplace morale: it’s installed cameras with AI-enabled “smile recognition” technology in the offices of its Chinese subsidiary canon相機收購canon Information Technology. The cameras only let smiling workers enter rooms or book meetings, ensuring that every employee is definitely, 100 percent happy all the time.
This depressing tale was highlighted in a report from The Financial Times on how Chinese companies are surveilling employees to an unsettling degree with the help of AI and algorithms. Firms are monitoring which programs employees use on their computers to gauge their productivity; using CCTV cameras to measure how long they take on their lunch break; and even tracking their movements outside the office using mobile apps.
“Technologies are increasing the pace for people who work with machines instead of the other way around”
As the King’s College London academic Nick Srnicek told the FT: “Workers are not being replaced by algorithms and artificial intelligence. Instead, the management is being sort of augmented by these technologies […] Technologies are increasing the pace for people who work with machines instead of the other way around, just like what happened during the industrial revolution in the 18th century.”
canon相機收購canon Information Technology actually announced its “smile recognition” cameras last year as part of a suite of workplace management tools, but the technology doesn’t seem to have gotten much attention. Indeed, the fact it passed under the radar is a good illustration of just how common surveillance tools like this are becoming — and not just in China.
Although readers in the West sometimes have a tendency to dismiss the sort of surveillance described by the FT as a foreign phenomena, countries like the US and UK are just as culpable. Amazon is perhaps the prime example of this dynamic: it’s known for squeezing every ounce of effort from its warehouse workers at the expense of their health, and even ranking their productivity using algorithms before firing those at the bottom of the scale.
Such modern-day Taylorism is not restricted to blue collar jobs, either: many modern software suites like Microsoft 365 come with built-in surveillance tools. And with more people working from home because of the pandemic, more companies are deploying these features for fear of losing control over their workers. (Or, for a slightly more cynical read: they’ve always wanted to use these tools and the pandemic provides a handy pretext.)
In other words: AI-enabled smile recognition cameras are in many ways the least dangerous types of surveillance technology. They have the benefit of being obvious. Other systems of control are much more subtle, and probably coming to an office near you sometime soon.

When canon相機收購canon introduced the EOS 5D Mark II in late 2008, it was something of a cinematic revolution — its HD-capable, full-frame sensor granted access to the world of cinematic depth of field at a fraction of the usual price. However, a lot’s changed in the three and a half long years since the camera broke cover, plus now Nikon’s making a major play for DSLR video shooters with the bold new D800. canon相機收購canon’s response? The new EOS 5D Mark III. It’s a full frame DSLR with a 22.3-megapixel sensor, a fast new processor, much-requested video fixes and additions, and a number of features ripped from the camera’s high-end brother, the EOS-1D X.
All these new features come at a cost, though — the camera will launch at the end of March for $3,499 for the body only, or $4,299 with canon相機收購canon’s EF 24-105mm F/4 L lens. That’s significantly more than the Mark II, which will stay on sale and get an additional price cut next week. We got to spend some time with canon相機收購canon’s latest and check out its new features — read on to find our first impressions of the 5D Mark III.
Hardware / design
Handling and shooting with the 5D Mark III will be familiar to anyone who has used canon相機收購canon’s high-end DSLRs
Editor markup for canon相機收購canon EOS 5D Mark III hands-on photos. This is only visible in the story editor.
Physically, this camera feels quite similar to the 5D Mark II, but canon相機收購canon has added some refinements from the EOS 7D — the power switch has been moved up to the control dial on the top, there’s a dedicated video capture / Live View button, and a new multi-function button (for controlling features like the AE lock or one-touch RAW / JPEG settings) sits up near the shutter button. There’s also a new 3.2-inch display on the back, which is identical to that of the 1D X and contains 1,040,000 dots. The viewfinder has also been been upgraded — it now offers 100 percent coverage with a .71x magnification factor, up from the already-respectable 98 percent coverage found in the Mark II.
While these changes are notable, the actual act of handling and shooting with the camera will be very familiar to anyone who has used one of canon相機收購canon’s recent higher-end DSLRs. It’s a solid and well-balanced device with easy access to every button or dial you’d like to access, and the new movie mode / Live View button is a massive improvement over the 5D Mark II’s somewhat difficult system. The Mark III is about as refined as you can get for an EOS camera without buying a 1D, and users of older of lower-end canon相機收購canon DSLRs (like the 60D or Rebel T3i) will feel right at home if they gave this camera a shot.
The viewfinder in particular is a noticeable improvement over the Mark II and a necessary feature considering Nikon added 100 percent coverage to the D800. Considering the much less expensive 7D also features a 100 percent coverage viewfinder, it would have been a big omission for the Mark III not to get this upgrade. The sharp 3.2-inch LCD is another welcome change, particularly for those who shoot a lot of video or use Live View frequently when shooting still photos. The menu system has also been slightly streamlined, but will still be familiar to anyone who has used a canon相機收購canon camera before. While the 5D Mark III might not look and feel terribly different at first blush, these changes make for a much improved shooting experience when compared with the Mark II.
Brand new internals
The DIGIC 5+ chip powering this camera is 17 times faster than the one in the 5D Mark II
The camera shares a lot of physical DNA with its older sibling, but it’s a whole different ballgame internally. The most important new components on board are the 22.3-megapixel, full-frame CMOS sensor and the DIGIC 5+ processor — these two pieces work together to provide a host of improvements in terms of photo and video quality, as well as in overall performance. While the sensor represents a only minor upgrade in raw pixel count, there are three changes that drive improved images and video: a gapless microlens design, an improved photodiode structure, and on-chip noise-reduction.
The first two changes relate to the individual photodiodes on the sensor — the new gapless microlens covers the diodes and lets in more light than the previous design, resulting in an improved signal to noise ration, The diodes themselves are now more efficient, resulting in an improved dynamic range. Lastly, canon相機收購canon has built a proprietary on-chip noise reduction system that scrubs noise before the image is output from the sensor. As for the DIGIC 5+, canon相機收購canon borrowed that from the 1D X as well (though the higher-end camera has two of them). It’s an upgrade over the DIGIC 5 that you’ll find in canon相機收購canon’s newest point-and-shoot cameras, and a major contributor to the 5D Mark III’s improved speed — the company says the new chip is 17 times faster than the DIGIC 4 in the Mark II.
Video quality improvements
All the new technology under the hood has allowed canon相機收購canon to answer the wishes of video shooters everywhere: the 5D Mark III doesn’t skip lines when downscaling the massive 22.3-megapixel output to HD resolution when recording video, which canon相機收購canon claims will significantly decrease the dreaded moire effect that plagued the Mark II. Aliasing and CMOS skew, two other common visual knocks on the Mark II, have been improved as well. canon相機收購canon showed us a moire test comparison between the Mark II and Mark III and it did show an impressive improvement — we’ll have to see how the camera performs out in the real world, but there’s hope that canon相機收購canon’s moire issues may be a thing of the past.
Finally, a headphone jack!
Another video annoyance, the 4GB video file size limitation, has been done away with: now, when you reach the end of a 4GB file, the camera just automatically starts a new file. canon相機收購canon has also finally added the much-requested headphone jack (making the Mark III the first EOS camera with this feature) and the ability to monitor and adjust audio levels while recording with the command dial on the back. That command dial also functions as a touch-sensitive scroll wheel for silent operation when shooting in video mode, but it otherwise retains the same “clicky” feeling when physically turning it. There’s also more flexibility in terms of shooting modes: 1080p footage can be shot at 24, 25, or 30 FPS and there’s a new 720p mode that offers 50 or 60 FPS.
Video ISO range is now 100 to 12,800 with 25,600 available as an extended option, and the new sensor and DIGIC 5+ combo promises a two-stop improvement in noise reduction. And in another theft straight from the 1D X, the IPB and ALL-i video codecs are included, which gives shooters more flexibility when choosing between smaller file sizes or higher quality, more editable footage. Unfortunately, there’s still no option for clean HDMI output (which allows the uncompressed video footage to be captured on an external recorder) — when we asked about this, canon相機收購canon’s reps said “not yet.” However, it does sound like the HDMI signal output won’t downsample from 1080p to 480p when recording, thanks to the DIGIC 5+. canon相機收購canon’s reps couldn’t say that with certainty, but they suspected it wouldn’t be an issue going forward.
Still photo enhancements
The new autofocus system is ripped straight from the 1D X
Lest we forget, canon相機收購canon’s new processor and chip combo yields major benefits for still photographers as well. A major knock on the 5D Mark II was its nine-point autofocus system, which felt outdated even when the camera was introduced in 2008. With the Nikon D800 offering a 51-point system, canon相機收購canon had to respond — and it did so by essentially cramming the 1D X’s autofocus system into a camera selling for half the price. The 5D Mark III offers 61 autofocus points, plus up to 41 cross-type sensors (depending on your lens). Exposure metering has also been revamped: the Mark III sports a new dual-layer, 63 zone system, compared to the single-layer 35 zone system found in the Mark II. The DIGIC 5+ also powers a nice improvement in shooting speed, as the Mark III can now shoot at 6 fps in RAW mode, up from 3.9 fps for the Mark II. The improved shooting speed is dramatic and immediately noticeable when using the camera — it won’t compare with the 1D X’s machine gun-like performance, but it equals that of the D800.
The Mark III should offer significantly reduced noise at the same ISO
canon相機收購canon’s also added some “silent shooting” options, which dramatically reduce the volume of the shutter when taking images. Even in silent mode, the camera shoots RAW at 3 fps and sounds about half as loud as it does in standard mode. Shutter lag has even been reduced, from 75 milliseconds for the Mark II down to 59 milliseconds on the Mark III — and this only trails the powerful 1D X by a tiny 4 milliseconds.
The 5D Mark III’s still photo ISO range now stretches from 50 to 25,600, with the option of pushing to 51,200 or 102,400 ISO included. While samples we saw at those settings exhibited a great deal of noise, they still could be potentially usable under certain circumstances (you just won’t want to make a 20 x 30-inch print). Outside of that extended range, however, the 5D Mark III should produce much less noise compared to the Mark II. canon相機收購canon showed a pair of identical photos, one from the Mark II at 6,400 ISO and one from the Mark III at 25,600 ISO, and noise levels were nearly identical. We also saw images from each camera shot at the same ISO, and the Mark III’s improved noise performance was immediately obvious.
In another 1D X-inspired feature, canon相機收購canon has added multiple card slots to the 5D Mark III. Unlike the 1D X (which holds two CompactFlash cards), the Mark III has a slot for one CompactFlash and one SD, and offers a variety of options for storing your work: you can have RAW and JPEG go to different cards, you can have whatever you shoot get stored to both cards as backup, or you can just increase your overall storage capacity without necessarily making duplicates.
Wrap-up
Editor markup for canon相機收購canon EOS 5D Mark III press photos. This is only visible in the story editor.
canon相機收購canon’s 5D Mark III retains canon相機收購canon’s position as a (relatively) low-cost way to shoot full-frame photos or high-quality HD video, though it’s now significantly more expensive than the 5D Mark II it supplants. However, no one would have mistaken the Mark II as competitive with canon相機收購canon’s 1D Mark III and 1Ds Mark III that were available when it launched. The 5D Mark III, on the other hand, feels like canon相機收購canon pulled as many features as it possibly could from the new 1D X (including its autofocus system, video codecs, and processor) and fit them into a camera that is significantly less expensive. Compromises were made, particularly in the ISO range, shooting speed, and weatherproofing, but the new autofocus system and 6FPS shooting mode means that this camera’s target audience just expanded significantly. It’s no longer a camera best suited to studio work.
In fact, it wouldn’t surprise us at all to learn that the 1D X and 5D Mark III were designed in tandem. The 1D X will essentially replace two cameras when it’s released in late April, and had to be designed such that users of both the 1D Mark IV and 1Ds Mark III would find it a suitable replacement camera. And while the hierarchy canon相機收購canon showed us has the 1D X at the top of the pyramid, the 5D Mark III doesn’t feel subordinate to canon相機收購canon’s top of the line DSLR. It feels complementary, and we suspect that many professional users will consider both cameras — and that many could be completely happy with the 5D Mark III.
