Partner to the newly designed sensor is a fresh engine—the X-Processor 5—which uses 64-bit processing to realize 3x faster speeds for both video and photo tasks compared to the X-T4. On the video side, this enables recording at up to 6.2K with high bitrates like ProRes 422 HQ or at high speeds, like with 240 fps recording at Full HD.On the stills end, this quick processing means faster shooting to suit photographing moving subjects. When working with an electronic shutter, shooting at up to 40 fps is possible, with a buffer of 140 consecutive uncompressed raw frame. With the mechanical shutter, shooting speeds up to 15 fps are possible, along with the ability to shoot upwards of 1000 raw frames in a single burst.
Benefitting both video and stills applications, this processing also benefits the sophisticated and AI-backed autofocus system, helps achieve a 14-stop dynamic range, and enables a broad sensitivity range from ISO 160-12800.
