OmniVision’s new 50MP OV50A smartphone sensor promises ‘DSLR level’ phase detection autofocus performance
Sensor manufacturer OmniVision has announced the specifications for the OV50A, a new 50MP 1/1.5″ smartphone camera sensor that offers 100% phase detection autofocus (PDAF) coverage.
The OV50A is built using OmniVision’s PureCel Plus-S stacked die technology and offers 50MP resolution with one micron pixel size, selective conversion gain, on-chip remosaic and quad phase detection (QPD) autofocus. OmniVision explains in its press release the benefits of its QPD autofocus technology, which it claims offers ‘DSLR level’ autofocus performance:
‘QPD enables 2×2 phase detection autofocus (PDAF) across the sensor’s entire image array, for 100% coverage. Unlike the microlens and half-shield PDAF technologies, which only capture 3–6% of the phase detection data, QPD uniquely captures 100% of this data for improved distance calculation, faster autofocus and better low-light performance.’
The QPD autofocus technology works not unlike Canon’s Dual Pixel AF technology. However, whereas Canon’s only has two pixels split left and right underneath a single micro lens, OmniVision splits each micro lens with four pixels, paired diagonally, to achieve focus. The advantage of this design is that unlike Canon’s Dual Pixel AF, the four diagonally-paired pixels provides cross-type (horizontal and vertical) sensitivity for consistent performance regardless of camera and subject orientation.
OmniVision also touts the sensor’s low-light performance as ‘the best in its class via the unique combination of a large 1.0 micron pixel size, selective conversion gain’s low-noise, high conversion gain mode, and […] the large 1/1.5” optical format.’ The sensor offers 2- and 3-exposure HDR blending, which works with the selective conversion gain to capture the most dynamic range possible.
The sensor can output 8K video at 30 frames per second (fps) as well as 4K video at 90 fps and 1080p at 240 fps. The 4K video can use near-pixel-binning for improved low-light performance when light is at a premium. Video output maxes out at 3.5Gbps via the sensor’s CPHY MIPI interface.
OmniVision suggests this sensor is destined for the standard and ultra-wide-angle cameras inside flagship smartphones. The sensor is said to be available in the second quarter of 2021, but no specific smartphone manufacturers were mentioned as customers.

OmniVision Debuts Its First Image Sensor With 100% Phase Detection Coverage for Superior Autofocus in Flagship and High End Smartphones
Combination of 1.0 Micron Pixel and 1/1.5” Optical Format With Selective Conversion Gain, 50MP Resolution and QPD Provides Premium Still and 8K Video Captures for Wide and Ultrawide Main Cameras
SANTA CLARA, Calif. – Feb. 16, 2021 – OmniVision Technologies, Inc., a leading developer of advanced digital imaging solutions, today announced in advance of Mobile World Congress Shanghai the OV50A image sensor, combining 50MP resolution, 1.0 micron pixel size, selective conversion gain and a 1/1.5”optical format with quad phase detection (QPD) autofocus technology and on-chip remosaic. QPD enables 2×2 phase detection autofocus (PDAF) across the sensor’s entire image array, for 100% coverage. Unlike the microlens and half-shield PDAF technologies, which only capture 3-6% of the phase detection data, QPD uniquely captures 100% of this data for improved distance calculation, faster autofocus and better low-light performance. In combination with on-chip remosaic for the QPD color filter array, the result is premium image quality for the wide and ultrawide main cameras in flagship and high end smartphones.
“One of the biggest selling points for mobile phones is camera performance, and they have been steadily closing the gap with DSLR cameras for years,” said Arun Jayaseelan, staff marketing manager at OmniVision. “Our QPD autofocus technology now makes that gap even smaller, by bringing DSLR level autofocus performance to smartphone cameras.”
The OV50A image sensor also provides the best low-light performance in its class, via the unique combination of a large 1.0 micron pixel size, selective conversion gain’s low-noise, high conversion gain mode, and its distinction as OmniVision’s first high end mobile sensor to be offered in the large 1/1.5”optical format. Additionally, this sensor offers excellent HDR through 2- and 3-exposure staggered HDR timing, along with selective conversion gain for the optimum balance between low-light image quality and HDR. These features provide mobile designers with maximum flexibility to select the best HDR method for the contrasting light and dark areas in any scene.
Built on OmniVision’s PureCel® Plus-S stacked die technology, the OV50A integrates an on-chip, QPD color filter array and hardware remosaic, which provides significantly improved autofocus performance along with high quality, 50MP Bayer output, or 8K video, in real time. This sensor can also use near-pixel binning to output a 12.5MP image for 4K2K video with four times the sensitivity, yielding 2.0 micron-equivalent performance for preview and video. In either case, the OV50A can consistently capture the highest quality images, as well as enabling 2x digital crop zoom with 12.5MP resolution and fast mode switch.
Output formats include 50MP, or 8K video, with QPD autofocus at 30 frames per second (fps), 12.5MP with QPD autofocus at 60fps, 4K2K video with QPD autofocus at 90fps, 1080p at 240fps and 720p at 480fps. All of these options can be output at up to 3.5 Gsps per trio, over the sensor’s CPHY MIPI interface.
OV50A samples are expected in Q2 2021. Contact your OmniVision sales representative for more information: www.ovt.com/contact-sales.

Canon's latest feature costs $120 and is meant for school photographers
Image: Canon |
Canon has announced a new ‘Cropping Guide’ firmware update, which aims to make framing portraits easy and consistent. The feature costs $120 per camera and is available on the EOS R50, R10 and R7.
According to Canon’s website, the function includes four guides with built-in borders for standard print sizes. The guides are designed to work whether you’re shooting in landscape or portrait and to let you frame both headshots and full-body portraits.
The framing guides are clearly meant for professionals shooting high-throughput portraits; think school photos, sports events, or corporate events where everyone in the company has their picture taken. Driving this point home, Canon’s press release mentions that it’ll show the feature off at the School Photographers Association of California trade show early next year.
There is one caveat for anyone looking to add the function to their camera: you have to send your camera to a service center to activate it. That could be a problem if you only have a single camera body, though that’s likely not the case for most working photographers. Also, a lot of mass portraiture work happens in cycles; schools and sports leagues all tend to have pictures taken at the same time of year. Canon also sells versions of the EOS R50, R10 and R7 with the feature pre-installed at a $120 markup from the normal models’ MSRPs.
Still, it’s hard to ignore that Panasonic and Sony sell similar features delivered via an immediate firmware download. There are some other differences, too: Canon’s framing guide is only available on its APS-C cameras, while Panasonic and Sony limit their versions to more expensive full-frame cameras like the Lumix S5 II, a7 IV and a9 III.
Panasonic’s solution, called Lumix Volume Photography, also goes further than just including frame guides; it also integrates with Opticon scanners, letting you bake a student’s information into the photo file for easier sorting. However, it also costs $199, versus Canon’s $120 and Sony’s $150.

There will be people who balk at any mention of paying for new features, and you could argue that it’s a slippery slope leading to cameras riddled with microtransactions or subscriptions. Ricoh started selling an $80 software graduated ND filter feature for some of its cameras earlier this year, but surely we don’t want that to become the new normal.
On the other hand, this specific function is something that most people buying these cameras will never want or use, so why should they pay for the development work that went into it or have to navigate around it in their menu system? Let the professionals who will almost immediately make the money back in time saved fund it instead of baking it into the price of the camera.
However Canon’s regular customers feel about paid functions, the company will likely only pay attention to how the pros respond. As we saw with Sony’s a1 II, pricing for professional products is based on how much the market will bear rather than the types of value calculations hobbyists make. If you’re a professional who shoots portraits, we’d love to hear from you in the comments. Would you or your company pay for this feature, and would its availability be a big factor in you choosing which camera to buy?

Gear of the Year – Richard's choice: Leica D-Lux8
There’s a lot of gloom surrounding cameras and photography, in the past year or so. The devastating impact of smartphones on mass-market cameras seems to be being followed by a wave of AI-generated images that threaten to wash photography away as a creative form, if you believe those prognosticators with half-empty glasses. And yet it’s hard to think of a year in which I’ve found it so difficult to choose a piece of gear to call out, because so many of them have been so good.
Having chosen Nikon’s Z8 last year, the obvious decision this time round would be Canon’s EOS R5 II: a camera that’s almost unbelievably good at almost anything you might ask of it. The Nikon’s Z6III’s performance comes with a small footnote, but overall it’s also sensationally capable and costs over 40% less.
On the lens side of things, Sony has made a usefully small full-frame F2.8 zoom and Sigma has developed what is essentially a full-frame version of its 18-35mm F1.8, creating the world’s first AF F1.8 zoom for full-frame in the process. Then there’s Fujifilm: not content with updating probably the best kit lens on the market (albeit with a loss of speed and reach at the long end counteracting the gain of width at the other), it’s also replaced its premium standard zoom with a much smaller, lighter optic.
The Fujifilm 16-50mm F2.8 R LM WR II would probably be my choice in any other year. Its lightweight re-imagining meant it was small enough for me to take on a five-day hike across North Wales, and helped me assemble one of the best galleries I think I’ve ever shot.
“It’s just exciting to see anyone introduce an enthusiast compact”
And yet instead of any of these worthy winners, I’m going to choose a camera whose merits come with some appreciable caveats and that I’ll spend much of this article appearing to criticize.
Let’s get this straight out of the gate: in many respects the Leica D-Lux8 is refresh of a seven year old camera. And its price tag of $1599 lands somewhere between fanciful and absurd.
And yet, in an age when second-hand Panasonic LX3s often attract 40% of their original price on eBay, despite their wonky skin tones, outdated performance and 2008-vintage batteries, it’s just exciting to see anyone introduce an enthusiast compact.
And while the D-Lux8 shares the bulk of its hardware with the LX100 II, it gains one of the most photo-focused user interfaces I’ve had the good fortune to use in the seventeen years I’ve been writing about cameras.
It also gains a much less distracting viewfinder, which I also appreciate, and its AF tracking, while not coming close to the standards of modern mirrorless cameras, is also improved.
There’s a nagging doubt whenever I’ve used a recent D-Lux or LX100 of why it doesn’t feel even more special, given its dial layout and aperture ring suggests it should feel like a smaller X100, but with a zoom. Personally I think the added lag of waiting for the motor-driven zoom to respond helps to distance your input from the camera’s reaction. Or it could just be that the photos don’t look as good, thanks to its less sharp lens, deeper minimum depth-of-field and absence of Film Simulation fairy dust.
But the 8’s new interface is delightfully shutter speed and aperture focused. There aren’t many custom buttons and you don’t need a great many: it’s a good-looking little camera that focuses your attention on taking photos. And that’s something I’ve really missed.
Maybe there’s still time for another blossoming of enthusiast compacts, now they’re starting to find an audience, retrospectively. Or maybe I just need to accept that my own preferences don’t match those of the wider market.
But even if the D-Lux8 doesn’t herald a new Spring for the serious compact, it’s not a bad note for the category to go out on. Price aside, it’s a lovely little camera.

Canon makes Super35 global shutter sensor available to third parties
Canon’s LI5070SA sensor delivers 4K at up to 60p with no rolling shutter, with Canon suggesting ‘Cinema’ as one of its potential applications.
Image: Canon |
Canon has made a 4K/60-capable Super35 (∼APS-C) video sensor with global shutter available to third-party buyers.
The 10.3MP sensor added to the product page of its industrial equipment and semiconductor business unit is 27.4 x 15.3mm, making it a 1.34x crop, relative to a full-frame stills camera, but in a roughly 16:9 aspect ratio.
Its 4288 x 2398 pixel count is clearly designed for delivering 4K footage. We’d usually expect Canon to have already offered it in a camera, if it planned to, before offering it to external users.
Canon sold a 4K/60 Super35 ‘GS’ global shutter version of its EOS C700 camera, back in 2017, though available specs suggest its sensor was slightly smaller, so presumably wasn’t the same as the one now being offered to external companies. Notably, Canon claimed its dynamic range was one stop lower than the progressive scan Super35 chip in the regular C700 model. There’s still a chance this new chip will underpin a successor to the C700 GS.

At present, we’re not aware of any other consumer camera maker using Canon sensors. Specialist industrial / security camera makers such as Illunis have used its sensors to make high-speed and high-resolution cameras for applications such as aerial photography and machine vision applications, but we’ve not seen its 120MP or 250MP APS-H chips in consumer cameras, including those from Canon itself.
Canon said it was developing a DSLR based on its 120MP sensor, back in 2015. Prototypes based on EOS 5DS bodies appeared at trade shows, but no final product ever emerged.
Canon’s semiconductor business also offers a “full-frame” global shutter sensor. Again this has a roughly 16:9 aspect ratio and proposed uses include microscopy, factory automation and traffic surveillance. This sensor has been available since early 2023.
