  4. 4Canon EOS R6 Mark II, Native ISO maximum: ISO 204800 (H) is an expanded setting; the native range tops out at ISO 102400.
  5. 5Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
  6. 6Canon EOS R100, In-body image stabilization: No in-body stabilization; shake correction relies on IS lenses or Movie Digital IS.
  7. 7Canon EOS R6 Mark II, In-body image stabilization: The 8-stop rating combines lens optical IS with in-body IS; results vary by lens.
  8. 8Ricoh GR IV, In-body image stabilization: Ricoh's 6.0-stop rating applies at frame centre; periphery is rated 4.0 stops (CIPA 2024).
  9. 9Ricoh GR IV, Sensor type: The sensor is a back-illuminated (BSI) CMOS type; mapped to 'cmos' as no BSI option is listed.
  10. 10Ricoh GR IV, Aspect ratios: 3:2 is native to the 23.3 x 15.5 mm sensor; 4:3, 1:1 and 16:9 are in-camera crop modes.
  11. 11Sony a7 IV, Continuous shooting (mechanical): 10 fps applies to compressed RAW/JPEG/HEIF; drops to 6 fps for lossless or uncompressed RAW.
  12. 12Ricoh GR IV, Continuous shooting (mechanical): The review cites 4 fps continuous without specifying shutter type.
  13. 13Canon EOS R100, Continuous shooting (electronic): The electronic (silent) shutter does not support continuous shooting on this camera.
  14. 14Ricoh GR IV, Max mechanical shutter speed: 1/4000 s requires F5.6 or a smaller aperture; at F2.8 the limit is 1/2500 s.
  15. 15Canon 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.
  16. 16Ricoh GR IV, AF subject detection: Only face/eye detection is offered; no animal or vehicle subject recognition is listed.
  17. 17Sony a7 IV, 4K max frame rate: 4K 60p is only available in Super35mm crop; full-frame 4K tops out at 30p.
