The DIGIC Accelerator chip is a completely new front-end processor developed by Canon to supplement the power of the proven DIGIC X processor. The EOS R5 Mark II is a worthy successor to the incredibly versatile EOS R5 bringing a host of new features that make this the most powerful EOS 5 series camera ever. The DIGIC Accelerator handles the processing that makes so many of the new features of this camera possible, allowing the DIGIC X chip to focus solely on image processing, again contributing to incredible speed. It starts with a brand-new 45MP sensor that is back illuminated and stacked for blazingly fast read-out speeds that allow for a 30 fps electronic shutter, then builds on that with major focus improvements, increased video capabilities, and so much more.
