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.

Atomos has reportedly stopped working on its 8K global sensor

Image: Atomos |
In late 2022, Atomos told investors that it had “completed development of a world class 8K video sensor” and that it was “actively exploring opportunities for commercialisation” and holding talks with camera makers that it said were “showing great interest.” In an interview with PetaPixel later that year, the company said it was a full-frame, global shutter sensor capable of capturing 8K at 60fps with up to 15 stops of dynamic range, all while drawing just 2W of power.
We’ve heard very little about the project since then, but PetaPixel has just reported that it’s been abandoned, citing a conversation with the company’s COO. Currently, there are no further details about when the call was made to sideline the sensor or why that decision was made. We’ve reached out to Atomos and will update this story if we hear back.
While there’s been very little news about the sensor – dubbed the ‘Sapphire F8’ – since 2022, it seemed like an interesting proposition. Global shutters are especially useful for video applications, where rolling shutters can cause distortion on fast-moving subjects or during quick camera movements.
In 2022, the Sapphire would’ve been ahead of the curve
While several cinema-focused cameras have used the tech over the years, it’s only recently become available in cameras with larger (full-frame or above) sensors. When Red announced the V-Raptor X in early 2024, it said it was the “first available large format global shutter” cinema camera. Around the same time, Sony’s a9 III became the first full-frame mirrorless camera to feature a global shutter. In 2022, Atomos’ Sapphire project, developed after it acquired rights and technical staff from broadcast equipment company Grass Valley in 2017, would’ve been ahead of the curve.
Whatever caused the company to drop the project, it’s unfortunate that there won’t be more competition in the high-end sensor market. Making a sensor is no small feat, and neither is actually getting it into a finished product – something Atomos already knew since work on the Sapphire began during a project to create a cinema camera, which also wound up being canceled.

Are embedded Instagram posts a case of copyright infringement? Supreme Court asked to decide

Photo: Abby Ferguson |
Embedding social media posts has become a widespread practice and a critical tool for all sorts of websites. It allows sites to share content without hosting it themselves, opening the doors to showcase more dynamic content and user-generated or brand materials. Now, though, a photographer is asking the US Supreme Court to consider if embedding social media content is a violation of copyright.
As initially reported by Digital Camera World, photographer Elliot McGucken filed a petition for certiorari (a request to review) on March 28. This petition is part of his lawsuit against media company Valnet, Inc., which runs thetravel.com. The lawsuit results from The Travel embedding 36 photographs in McGucken’s Instagram posts across multiple articles without his permission. The case argues that embedding a copyrighted work without the artist’s permission is copyright infringement.
This debate, which centers around the “server test,” is far from new. The server test was a guideline initially established in a 2007 Ninth Circuit Court decision. It essentially says that if a website hosts a copyrighted image on its own systems, it is a copyright violation. But if the website uses third-party hosting, such as by embedding a social media post or an image from an artist’s website, it does not violate copyright.
There have been multiple challenges since the initial guideline was established. However, the most recent (outside of this new case) was in 2023, when photographers Alexis Hunley and Matthew Brauer filed a class action lawsuit against Instagram. They claimed that Instagram violated their copyright by allowing Time and Buzzfeed to embed photos they shared on their Instagram profiles. A three-judge panel at the 9th US Circuit Court of Appeals ruled that Instagram was not liable for copyright infringement, though, explaining that when a photo or video is embedded, no copy is made.
The district courts and Ninth Circuit court have already dismissed the complaints, but the photographer has now asked the Supreme Court to weigh in. The petition gives multiple reasons for why it should be granted, one of which is that it “presents a clear legal question that has divided the federal courts.” However, as VitalLaw reports, district courts in the Second, Fifth and Tenth Circuits, including a federal court in Manhattan, have all rejected it.
Instagram, like many other social media platforms, allows users to turn off embedding, which prevents websites from sharing content in this way. Instagram rolled this out in 2021, and users can change the setting under the “How others can interact with you” option inside the Settings menu.
The Supreme Court has until May 1 to issue a response.

PowerShot V1 | 25.6mm (50mm equiv.) | F4.5 | 1/640 sec. | ISO 125 Photo: Mitchell Clark |
Canon recently made its PowerShot V1 compact available globally, after it was initially launched for the Asian market. While the company’s marketing it as a vlogging camera, photographers also seem to have taken an interest in it, with its reasonably large Type 1.4 (18.4 x 12.3mm) sensor paired with a 16-50mm equiv. F2.8-4.5 lens.
We’ve gotten the opportunity to shoot with it a bit and have put together a sample gallery, which should give you some idea of how the sensor and lens perform. We’ll dig deeper into image quality in our full review.
Given that it’s a vlogging camera, we’ve also put together some sample footage taken with it. It’s embedded below, though do note that you may need to click through to watch the video on YouTube if you want to see it at its maximum quality.
Please do not reproduce any of these images on a website or any newsletter/magazine without prior permission (see our copyright page). We make the originals available for private users to download to their own machines for personal examination or printing; we do so in good faith, so please don’t abuse it.
