  2. 2Ricoh GR IV, Launch price: Launch MSRP per the review; Ricoh's US store currently lists $1,599.95.
  3. 3Sony a1 II, High resolution pixel-shift mode: 4- or 16-shot pixel shift composites are merged with Sony's Imaging Edge Desktop PC software.
  4. 4Canon EOS R100, Native ISO maximum: ISO 25600 (H) is an expanded setting, not a native sensitivity.
  5. 5Sony a1 II, In-body image stabilization: 8.5 stops is the CIPA centre rating; 7.0 stops at the periphery.
  6. 6Nikon Z9, In-body image stabilization: The 6.0-stop rating requires Synchro VR, combining in-body 5-axis VR with 2-axis lens VR on compatible lenses.
  7. 7Canon EOS R100, In-body image stabilization: No in-body stabilization; shake correction relies on IS lenses or Movie Digital IS.
  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. 11Ricoh GR IV, Continuous shooting (mechanical): The review cites 4 fps continuous without specifying shutter type.
  12. 12Canon EOS R100, Continuous shooting (electronic): The electronic (silent) shutter does not support continuous shooting on this camera.
  13. 13Ricoh 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.
  14. 14Sony a1 II, Pre-burst capture duration: Pre-capture buffers between 0.03 s and 1 s of frames before full shutter press.
  15. 15Nikon Z9, Pre-burst capture duration: Pre-Release Capture is only available in the C30 and C120 high-speed frame capture modes.
  16. 16Ricoh GR IV, AF subject detection: Only face/eye detection is offered; no animal or vehicle subject recognition is listed.
  17. 17Sony a1 II, 4K max frame rate: 4K 100p/120p recording uses a 1.1x crop.
  18. 18Sony a1 II, 4K max frame rate (full width): Full-width 4K tops out at 59.94p; 4K 100/120p requires a 1.1x crop.
  19. 19Canon EOS R100, 4K max frame rate (full width): All 4K recording uses a ~1.6x centre crop, so no full-width 4K mode exists.
  20. 20Sony a1 II, Raw video recording: 16-bit RAW video can only be output over HDMI to an external recorder; no internal RAW recording.
  21. 21Canon 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.

  24. 24Ricoh GR IV, Memory card slots: Single microSD slot, plus 53 GB internal memory that cannot record to both at once.
  25. 25Sony a1 II, Weather sealing: Sony specifies dust- and moisture-resistant sealing; no formal IP rating is published.
  26. 26Canon EOS R100, Weight: CIPA weight: body with battery and memory card, without lens.
  27. 27Sony a1 II, Depth: Sony also lists 72.8 mm depth measured from grip to monitor, excluding the grip protrusion.
  28. 28Canon EOS R100, USB charging & power delivery: The battery must be charged in the external LC-E17E charger; no USB power delivery.
