Notes on 18 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 R100, Native ISO maximum: ISO 25600 (H) is an expanded setting, not a native sensitivity.
  3. 3Canon EOS R100, In-body image stabilization: No in-body stabilization; shake correction relies on IS lenses or Movie Digital IS.
  4. 4Ricoh GR IV, In-body image stabilization: Ricoh's 6.0-stop rating applies at frame centre; periphery is rated 4.0 stops (CIPA 2024).
  5. 5Ricoh GR IV, Sensor type: The sensor is a back-illuminated (BSI) CMOS type; mapped to 'cmos' as no BSI option is listed.
  6. 6Ricoh 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.
  7. 7Ricoh GR IV, Continuous shooting (mechanical): The review cites 4 fps continuous without specifying shutter type.
  8. 8Canon EOS R100, Continuous shooting (electronic): The electronic (silent) shutter does not support continuous shooting on this camera.
  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. 10Ricoh GR IV, AF subject detection: Only face/eye detection is offered; no animal or vehicle subject recognition is listed.
  11. 11Canon EOS R100, 4K max frame rate (full width): All 4K recording uses a ~1.6x centre crop, so no full-width 4K mode exists.
  12. 12Canon EOS R100, Viewfinder magnification: Canon's 0.95x is quoted with a 50mm lens on APS-C; in 35mm-equivalent terms it is 0.59x.
  13. 13Ricoh GR IV, Battery life: CIPA-rated at 23°C with a fully charged DB-120 battery.
  14. 14Ricoh GR IV, Memory card slots: Single microSD slot, plus 53 GB internal memory that cannot record to both at once.
  15. 15Canon EOS R100, Weight: CIPA weight: body with battery and memory card, without lens.
  16. 16Canon EOS R100, USB charging & power delivery: The battery must be charged in the external LC-E17E charger; no USB power delivery.
  17. 17Ricoh GR IV, USB charging & power delivery: Battery charges and camera draws power in-body over USB-C; fast charging needs a USB-PD adapter.
  18. 18Ricoh GR IV, HDMI port type: Video output is DisplayPort over USB-C; there is no HDMI connector.
