Borrowed from the R3, the R6 Mark II’s upgraded processing suits the multimedia nature of the camera. Capable of processing high speed bursts as well as high-res 4K video, the DIGIC X supports up to 40 fps continuous shooting with a silent electronic shutter or 12 fps with a mechanical shutter, with AF and AE readings before each frame. There is also a 30 fps RAW Burst mode, which offers pre-release capture to record moments that happened up to 0.5-sec before you press the shutter.
Also, improved processing leads to improved low-light performance, with the sensitivity range now extending from ISO 100-102400, and expandable to ISO 204800 for working in very difficult lighting conditions.
