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.

Image of Palestinian boy with amputated limbs wins World Press Photo of the Year

World Press Photo has announced its 2025 Photo of the Year, along with two finalists, highlighting some of the most impactful photojournalism of the past year. 3,778 photographers submitted 59,320 photographs, and DPReview recently covered the category winners. This year’s top honor, revealed last night, was bestowed upon Samar Abu Elouf, a Palestinian photojournalist based in Doha, for The New York Times.
Her winning image is a portrait of Mahmoud Ajjour, a young boy wounded while fleeing an Israeli airstrike in Gaza in March 2024. The boy had turned his back to urge his family to move faster when an explosion tore through the street, severing one of his arms and damaging the other. It’s a stark depiction of the toll ongoing violence has taken on the denizens of the region.
Elouf was evacuated from Gaza in late 2023. She shares an apartment complex with Ajjor, the double amputee subject of her image. In recent months, she has continued to document the lives of a small number of severely-wounded Gazans who, like Mahmoud, were able to leave for medical treatment.
Two other finalists were selected as runners-up: John Moore for Night Crossing, depicting Chinese migrants warming themselves at the US-Mexico border at night. Musuk Nolte was also recognized for Droughts in the Amazon, capturing a young man bringing food to his mother in the drought-ridden village of Manacapuru.
“I remain endlessly grateful for the photographers who, despite the personal risks and emotional costs, record these stories to give all of us the opportunity to understand, empathise, and be inspired to action,” said Joumana El Zein Khoury, World Press Photo’s Executive Director.
The awarded stories will be shown to millions as part of the World Press Photo annual traveling exhibition in over 60 locations worldwide. These locations include the premiere in Amsterdam and then move on to other significant metropolises, including London, Rome, Berlin, Vienna, and Budapest. More information about the images and photographers can be found on the World Press Photo site.

Canon EOS R1 shooting experience: let's see it in action

Canon EOS R1 | RF 70-200mm F2.8 L IS USM Z | 200mm | F4 | 1/1000 sec | ISO 3200 Photo: Mitchell Clark |
Canon’s EOS R1 is the company’s first ‘1 series’ flagship camera to be mirrorless and is specifically aimed at sports and action photographers. Given its narrow focus, we wanted to test it out at a professional sports game – preferably one supported by its Action Priority autofocus mode, which Canon says will recognize when players are performing a specific action and automatically focus on them.
Thankfully, we were able to get a media pass to photograph a Spokane Velocity FC game, which was the perfect opportunity to put the EOS R1 to the test. A caveat before we start: I am by no means a professional sports photographer, nor am I a football expert. However, part of the pitch for Action Priority autofocus is that it’s able to react to what’s happening in the game automatically, which made this an especially interesting test of its abilities, even though most people looking likely to buy an R1 are fully capable of shooting a game without it.
So how’d it do? Quite well, I found. It made shooting feel natural; I would move the camera along with the action, and most of the time, it just handled subject selection, making sure the player in control of the ball was the one in focus. However, it clearly wasn’t a magical replacement for talent, either. There were a few times it decided to track a player who wasn’t involved in the action, though it was relatively easy to correct it by manually putting the AF tracking point over the player.

Despite its occasional missteps, upon reviewing my shots, I found that Action Priority mode got me far better results than the combination of my football-tracking skills and standard subject recognition did. The EOS R1 was very tenacious at tracking people and excelled at keeping them in focus – which is great if you have the skill and knowledge necessary to know who to track and when to start tracking someone else.
I actually got the chance to talk to someone with those skills. One of the professional photographers at the game asked what I was shooting with, then said they also use an EOS R1; previously, they’d used an EOS R3. When I asked what they thought of the Action Priority mode, they said they didn’t think it made much of a difference. Given that they’d essentially trained themselves to do what it does, it’s not surprising that they didn’t find it as useful as I – someone without that training – did. However, they did find the EOS R1’s standard subject detection to be stickier than the EOS R3’s, especially when players were passing in front of and behind each other.
They were very fond of the camera’s Eye Control autofocus, where the camera automatically places the focus point on whatever you’re looking at. Despite having calibrated it a few times, I couldn’t get it to work reliably enough for me to be an asset rather than a liability. I tried it for a little bit at the game but ended up turning it off. However, it’s easy to see how it could improve the shooting experience if it does work for you – rather than relying on the camera to figure out what player is important, you can just follow the action with your eye.
Getting back to Action Priority mode, I did bump up against a few limitations with the system. It’s only available when using the electronic shutter and can’t be used with the EOS R1’s anti-flicker feature. While the camera’s readout is jaw-droppingly quick – I didn’t notice any rolling shutter artifacts on soccer balls in mid-flight – you will still see banding on electronic screens and under some LED lights.
The former was definitely an issue at the Spokane One stadium, and I found myself having to choose between giving myself a better chance of capturing the game with Action Priority and not having some quite distracting artifacts in the background. With that said the mechanical shutter on the EOS R1 can only shoot at 12fps instead of 40, which helped make the decision a bit easier.
I also found myself wishing that the pre-burst capture feature was configurable. The amount it buffers is based on your shooting speed: Canon’s manual says that in the 40 shots per second mode, it’ll buffer around half a second, but there’s no setting to control for how long or how many shots you’d like it to buffer.
Because my shooting style involves starting focus tracking with a half-press of the shutter button well before actually taking the photo, I wound up filling almost a third of my storage in the first half-hour of the game since every shot I took saved the 20 shots before it. Rather than trying to get myself used to back-button focusing, which doesn’t start pre-capture*, in the middle of the game, I just turned it off, but I feel like I could’ve gotten a few more good shots if I could’ve used the pre-burst capture, but set to only save five or ten photos from before the shutter press.
* And, in fact, cannot be set to start pre-capture, something that irked the pro I talked to.
Also, Canon, while I have your attention, why can’t I set one of my custom buttons to turn pre-burst capture on and off? To get around this, I followed Brian Worley’s trick of setting up a custom mode that’s exactly the same as my manual shooting mode, except with pre-capture off, but even that’s a bad solution. For one, there’s only one button you can assign to switch between modes, but also, if I made any changes while I was shooting pre-capture, those wouldn’t be carried over when I switched modes to turn it off.
While I’ve picked a lot of nits here, there were, unsurprisingly, a lot of things the EOS R1 did right. Its buffer felt endless – during the game, the camera only ever stopped shooting when I took my finger off the shutter, and never because it had to stop and write the photos to the card. At home, I let it run at 40fps for around 20 seconds and still didn’t reach the bottom of the buffer.
The battery had a similar amount of stamina. Over the course of the 90-ish minute game I shot mostly using the viewfinder and took around 9000 photos. (If you’re not confident that you can capture the decisive moment, you might as well capture every moment.) At the end of the day, I still had three out of four bars of battery and would’ve felt quite comfortable shooting for another 90 minutes. I couldn’t have, of course, but the camera could.
That’s probably the moral of the story. It’s no shock that using the EOS R1 didn’t immediately make me a pro sports photographer. Action Priority mode did, however, let me capture moments that only pro sports photographers could’ve not so long ago, and I suspect that Eye Control could’ve done the same if I could get it to work reliably for me.
It’s easy to imagine that sort of thing being really exciting as it makes its way into more accessible models – there’s always been something of a Catch-22 where entry-level cameras aimed at beginners come with the autofocus systems that offer the least assistance. Something like Action Priority mode or Eye Control could help parents capture their children’s sporting achievements without requiring them to become pro photographers or buy high-end cameras that cost thousands of dollars.

That future may be a ways off, though, and it doesn’t really help tell the story of the EOS R1, a camera almost exclusively for pros. That’s not to say that they won’t use those features, just that they’ll have different considerations when doing so; is Action Priority worth narrowing your shooting options and giving up some manual control so you can fully focus on composition and understanding the state of play, and can you rely on Eye Control when everything’s on the line?
Realistically, I’m not the person to answer those questions. However, it’s interesting that Canon added so many features designed to make a camera that’ll likely only ever be used by professionals easier to use. It’s like getting into an F1 car and discovering that, alongside all the manual controls, it actually has a quite capable self-driving system. The surprising part isn’t that the EOS R1 was up to the task of shooting the game – it’s essentially designed from the ground up to do that – but I wasn’t expecting it to also help me out so much along the way.
