  7. 7Canon EOS R6 Mark III, Pre-burst capture duration: Works only in the 40 fps electronic-shutter mode; Canon states it as up to 20 frames.
  8. 8Canon EOS R5 Mark II, Pre-burst capture duration: Up to 15 shots can be buffered before you fully press the shutter, which is about half a second at 30 fps.
  9. 9Canon EOS R6 Mark II, Pre-burst capture duration: Pre-release capture works in RAW burst mode and buffers up to 0.5s of action before full shutter press.
  10. 10Canon EOS R6 Mark III, AF subject detection: Car detection is tuned for racing cars, per Canon.
  11. 11Canon EOS R6 Mark III, Max video resolution: 7K is available only in RAW Video mode; standard MP4 recording tops out at 4K.
