We'll delve into this later in the review. The oversampled footage taken from a Super 35 (~APS-C) region of the sensor is still expected to look better than the subsampled capture from the full sensor width but both are supposedly improved by the new processing chain. Sony also says the improved processing will benefit video shooting. This means a camera with a touchscreen and dedicated joystick for AF point positioning, a camera with a deeper grip and improved customization, with better laid-out menus and much improved battery life. However, the adoption of the processing systems, algorithms and refinements introduced on the a9 all have their benefits. Sony says the a7R III is based around the same 42MP back side illuminated CMOS sensor as its immediate predecessor, so doesn't gain the full speed advantages of the a9's Stacked CMOS chip (in terms of AF performance, continuous shooting rate or reduced rolling shutter in video and electronic shutter mode).
