Notes on 29 values — test conditions and caveats
  1. 1Ricoh GR IV, Launch price: Launch MSRP per the review; Ricoh's US store currently lists $1,599.95.
  2. 2Canon EOS R6 Mark II, Native ISO maximum: ISO 204800 (H) is an expanded setting; the native range tops out at ISO 102400.
  3. 3Canon 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.
  4. 4Canon EOS R6 Mark II, In-body image stabilization: The 8-stop rating combines lens optical IS with in-body IS; results vary by lens.
  5. 5Ricoh GR IV, In-body image stabilization: Ricoh's 6.0-stop rating applies at frame centre; periphery is rated 4.0 stops (CIPA 2024).
  6. 6Ricoh GR IV, Sensor type: The sensor is a back-illuminated (BSI) CMOS type; mapped to 'cmos' as no BSI option is listed.
  7. 7Ricoh 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.
  8. 8Ricoh GR IV, Continuous shooting (mechanical): The review cites 4 fps continuous without specifying shutter type.
  9. 9Ricoh 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.
  10. 10Canon 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.
  11. 11Canon 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.
  12. 12Canon EOS R6 Mark III, AF subject detection: Car detection is tuned for racing cars, per Canon.
  13. 13Ricoh GR IV, AF subject detection: Only face/eye detection is offered; no animal or vehicle subject recognition is listed.
  14. 14Canon EOS R6 Mark III, Max video resolution: 7K is available only in RAW Video mode; standard MP4 recording tops out at 4K.
  15. 15Canon EOS R6 Mark II, Video codecs: Movies record H.264 by default; H.265/HEVC is used when Canon Log 3 or HDR PQ is enabled.
  16. 16Canon EOS R6 Mark III, 4K max frame rate (full width): 4K 120p uses the full width but is not oversampled; oversampled 4K tops out at 60p.
  17. 17Canon EOS R6 Mark II, Raw video recording: 6K ProRes RAW requires an external Atomos Ninja V+ recorder connected over HDMI.
  18. 18Canon EOS R6 Mark II, Video bit depth: Standard profiles record 8-bit 4:2:0; 10-bit 4:2:2 requires Canon Log 3 or HDR PQ.
  19. 19Canon EOS R6 Mark III, Video dynamic range (log): Canon's claim of 15+ stops in its Canon Log profiles, not a lab measurement.
  20. 20Canon EOS R6 Mark III, Battery life: 620 shots is CIPA's rating using the rear LCD (not the viewfinder) at 23°C; real-world results vary.
  21. 21Canon EOS R6 Mark II, Battery life: 760 shots is the CIPA power-saving rating with the rear LCD; Canon's smooth-mode rating is 580 shots.
  22. 22Ricoh GR IV, Battery life: CIPA-rated at 23°C with a fully charged DB-120 battery.
  23. 23Ricoh GR IV, Memory card slots: Single microSD slot, plus 53 GB internal memory that cannot record to both at once.
  24. 24Canon EOS R6 Mark II, Weather sealing: Sealed dust- and water-resistant build, not IP-rated; Canon cautions ingress cannot be fully prevented.
  25. 25Canon EOS R6 Mark III, USB charging & power delivery: USB-C charging and power need a capable USB-PD source such as Canon's PD-E2; not every power bank works.
  26. 26Canon EOS R6 Mark II, USB charging & power delivery: In-body USB charging and power supply require Canon's optional PD-E1 USB power adapter.
  27. 27Ricoh GR IV, USB charging & power delivery: Battery charges and camera draws power in-body over USB-C; fast charging needs a USB-PD adapter.
  28. 28Canon EOS R6 Mark II, Minimum operating temperature: Canon's product manual rates 0–40°C; regional Canon spec sheets list a 2°C minimum.
  29. 29Ricoh GR IV, HDMI port type: Video output is DisplayPort over USB-C; there is no HDMI connector.
