It’s still early in the year but it seems that the Canon EOS R5 with its high resolution, 45 megapixel, full-frame sensor is in the lead for excellent still image quality. Even with those large files, the speedy Canon EOS R5 can capture up to 20 frames per second in continuous shooting mode. The Canon EOS R6, Nikon Z6 II, and Sony A7 IV are also great ways to get into the full-frame mirrorless camera market if you have some money to make the investment.
