  7. 7Sony RX100 VII, In-body image stabilization: Sony rates the optical (lens-shift) SteadyShot at 4.0 stops at the 200 mm telephoto end, not a body-only CIPA figure.
  8. 8Ricoh GR IV, Sensor type: The sensor is a back-illuminated (BSI) CMOS type; mapped to 'cmos' as no BSI option is listed.
  9. 9Nikon Z 30, Aspect ratios: Native DX ratio is 3:2; 1:1 and 16:9 are in-camera crop modes.
  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 RX100 VII, Aspect ratios: 4:3, 16:9 and 1:1 sizes are in-camera crop modes over the native 3:2 sensor area.
  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. 13Nikon Z 30, Continuous shooting (mechanical): Nikon's in-house measured maximum; the rate is approximate.
  14. 14Ricoh GR IV, Continuous shooting (mechanical): The review cites 4 fps continuous without specifying shutter type.
  15. 15Sony RX100 VII, Continuous shooting (mechanical): The 'Hi' burst setting is electronic-shutter only; 10 fps ('Mid') is the fastest mechanical-shutter continuous rate.
  16. 16Sony RX100 VII, Continuous shooting (electronic): Blackout-free 20 fps continuous includes AF/AE tracking; the separate 'Single Burst' mode takes 7 shots at up to 90 fps.
  17. 17Ricoh 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.
  18. 18Ricoh GR IV, AF subject detection: Only face/eye detection is offered; no animal or vehicle subject recognition is listed.
  19. 19Sony RX100 VII, AF subject detection: Maker names only human and animal recognition (Eye AF / Real-time Tracking); no bird or vehicle categories are listed.

  24. 24Sony RX100 VII, Raw video recording: Sony's movie-format list contains only XAVC S (H.264) and AVCHD; no raw video output is offered.
  25. 25Sony RX100 VII, Log profile support: S-Log2, S-Log3 and HLG log gammas are selectable via Picture Profile presets PP1–PP10.
  26. 26Sony a7 IV, Video dynamic range (log): Sony's claim for S-Log3 per internal tests; stated as 15+ stops.
  27. 27Nikon Z 30, Viewfinder resolution: The Z 30 has no electronic viewfinder; compose on the rear LCD.
  28. 28Sony a7 IV, Screen size: Sony rates the panel at 2.95in (3.0-type); most sources round to 3in.
  29. 29Sony RX100 VII, Screen articulation: Screen tilts up about 180° for selfies and down about 90°; it does not swing outward like a fully articulated display.

  35. 35Ricoh GR IV, Memory card slots: Single microSD slot, plus 53 GB internal memory that cannot record to both at once.
  36. 36Sony a7 IV, Weather sealing: Dust and moisture resistant but not IP-rated; Sony does not guarantee 100% sealing.
