  4. 4Sony a7 IV, Native ISO maximum: Native range tops out at ISO 51200; 50-204800 requires expanded ISO settings.
  5. 5Sony a7 V, In-body image stabilization: Measured at the center with an FE 50mm F1.2 GM lens mounted per CIPA 2024 standards with long exposure NR off.
  6. 6Canon EOS R6 Mark III, In-body image stabilization: 8.5 stops is Canon's best-case center rating with certain RF lenses; peripheral and other lenses see less, down to 7.5 stops.
  7. 7Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
  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 V, Continuous shooting (mechanical): Maximum continuous shooting speed achieved using mechanical shutter in Hi+ mode.
  12. 12Sony a7 IV, Continuous shooting (mechanical): 10 fps applies to compressed RAW/JPEG/HEIF; drops to 6 fps for lossless or uncompressed RAW.
  13. 13Ricoh GR IV, Continuous shooting (mechanical): The review cites 4 fps continuous without specifying shutter type.
  14. 14Sony a7 V, Continuous shooting (electronic): Maximum continuous shooting speed achieved using electronic shutter in Hi+ mode.
  15. 15Ricoh 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.
  16. 16Canon 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.
  17. 17Canon EOS R6 Mark III, AF subject detection: Car detection is tuned for racing cars, per Canon.
  18. 18Ricoh GR IV, AF subject detection: Only face/eye detection is offered; no animal or vehicle subject recognition is listed.
  19. 19Canon EOS R6 Mark III, Max video resolution: 7K is available only in RAW Video mode; standard MP4 recording tops out at 4K.
  20. 20Sony a7 V, 4K max frame rate: Maximum 4K frame rate is available in XAVC HS 4K 4:2:0 10-bit mode.
