It aims to offer vastly improved autofocus speeds

While Samsung has already broken the 100-megapixel barrier with the ISOCELL HMX and is working on a 250-megapixel sensor, the Korean tech giant is finding ways to improve 50-megapixel units with the ISOCELL GN1.

Aside from offering Tetracell tech—which combines the sensor’s 1.2um pixels with 4-to-1 pixel binning for bigger 2.4um pixels, the ISOCELL GN1 has an integrated Dual Pixel Autofocus system. With two photodiodes for each pixel, the tech allows for the sensor to have improved autofocus speeds even when shooting at a full 50-megapixel resolution.

The new sensor has key video features like Smart-ISO, real-time HDR and EIS, and native support for 8K30 video recording.

The ISOCELL GN1 is expected to go in production next month.
