  1. 1Ricoh GR IV, Launch price: Launch MSRP per the review; Ricoh's US store currently lists $1,599.95.
  2. 2Nikon Z 30, Sensor format: DX format is Nikon's name for its APS-C-size sensor (23.5 x 15.7 mm).
  3. 3Nikon Z 30, Native ISO maximum: Settings above ISO 51200 (102400, 204800) are expanded, not native.
  4. 4Canon 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.
  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. 7Nikon Z 30, Aspect ratios: Native DX ratio is 3:2; 1:1 and 16:9 are in-camera crop modes.
  8. 8Ricoh 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.
  9. 9Nikon Z 30, Continuous shooting (mechanical): Nikon's in-house measured maximum; the rate is approximate.
  10. 10Ricoh GR IV, Continuous shooting (mechanical): The review cites 4 fps continuous without specifying shutter type.
  11. 11Ricoh 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.
  12. 12Canon 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.
  13. 13Canon 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.
  14. 14Canon EOS R6 Mark III, AF subject detection: Car detection is tuned for racing cars, per Canon.
  15. 15Ricoh GR IV, AF subject detection: Only face/eye detection is offered; no animal or vehicle subject recognition is listed.
  16. 16Canon EOS R6 Mark III, Max video resolution: 7K is available only in RAW Video mode; standard MP4 recording tops out at 4K.
  17. 17Canon EOS R5 Mark II, Video codecs: Internal codecs are XF-HEVC S, XF-AVC S and H.264 MP4; ProRes RAW is recorded via HDMI to an external recorder.
  18. 18Canon 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.
  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. 20Nikon Z 30, Viewfinder resolution: The Z 30 has no electronic viewfinder; compose on the rear LCD.
  21. 21Canon 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.
  22. 22Nikon Z 30, Battery life: Figure is for the EN-EL25 battery; shot count differs with EN-EL25a.
  23. 23Ricoh GR IV, Battery life: CIPA-rated at 23°C with a fully charged DB-120 battery.
  24. 24Ricoh GR IV, Memory card slots: Single microSD slot, plus 53 GB internal memory that cannot record to both at once.
  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. 26Nikon Z 30, USB charging & power delivery: In-camera USB charging/power needs Nikon's optional EH-7P or EH-8P 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. 28Ricoh GR IV, HDMI port type: Video output is DisplayPort over USB-C; there is no HDMI connector.
