Sony Unveils LYT‑828 50MP Smartphone Sensor with Game-Changing 100 dB HDR

Highlights

• Sony’s LYT‑828 sensor launched with Hybrid Frame-HDR, combining single-frame and multi-frame HDR for a record 100 dB dynamic range and improved exposure accuracy via Loss-Less Exposure (LLE).
• A new charge-to-voltage circuit reduces noise for sharper low-light shots, while HDR remains active in all modes.
• Mass production begins late August 2025, with the sensor possibly debuting in the Vivo X300 Pro.

Sony has officially launched its latest mobile camera sensor, the LYT‑828. It is aimed straight at improving smartphone photography. This new 50-megapixel CMOS sensor is designed to deliver more realistic images with better performance in both bright and low-light conditions. Here’s more about the newly launched sensor.

Sony LYT‑828 Special – Key Features

The LYT‑828 is a 1/1.28-inch stacked sensor, succeeding the popular LYT‑818. It’s made for use in both main and sub-camera setups on smartphones. But the big highlight here is Sony’s new Hybrid Frame-HDR (HF-HDR) technology.

This advanced HDR system blends two approaches, single-frame HDR using Dual Conversion Gain (DCG) and multi-frame HDR by combining short exposure frames with DCG data. Thanks to this combo, the LYT‑828 achieves an impressive dynamic range of over 100 dB, the highest ever in a Sony mobile sensor.

This means you’ll get better control over highlights and shadows in tricky lighting. Paired with Loss-Less Exposure (LLE), the sensor can manage exposure even more accurately while improving the signal-to-noise ratio (SNR) for cleaner shots.

Sony has also packed in a special circuit to convert charge to voltage more efficiently. This helps cut down random noise, making low-light photos sharper and more detailed with less grain. Moreover, the low-power logic circuitry ensures that HDR is active in every mode, whether you’re previewing your shot or recording a video.

So, what you see on screen is very close to the final result.

Launch Timeline

Sony says the LYT‑828 will go into mass production by late August 2025, and we can expect to see it in high-end smartphones launching later this year.

Since the Vivo X200 Pro was the first to use the LYT‑818, there’s a good chance that the upcoming X300 Pro could debut the new LYT‑828.
