Notes on 42 values — test conditions and caveats
- 1Ricoh GR IV, Launch price: Launch MSRP per the review; Ricoh's US store currently lists $1,599.95.
- 2Sony a7 IV, Native ISO maximum: Native range tops out at ISO 51200; 50-204800 requires expanded ISO settings.
- 3Canon EOS R100, Native ISO maximum: ISO 25600 (H) is an expanded setting, not a native sensitivity.
- 4Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
- 5Canon EOS R100, In-body image stabilization: No in-body stabilization; shake correction relies on IS lenses or Movie Digital IS.
- 6Ricoh GR IV, In-body image stabilization: Ricoh's 6.0-stop rating applies at frame centre; periphery is rated 4.0 stops (CIPA 2024).
- 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.
- 8Ricoh GR IV, Sensor type: The sensor is a back-illuminated (BSI) CMOS type; mapped to 'cmos' as no BSI option is listed.
- 9Ricoh 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.
- 10Sony RX100 VII, Aspect ratios: 4:3, 16:9 and 1:1 sizes are in-camera crop modes over the native 3:2 sensor area.
- 11Sony a7 IV, Continuous shooting (mechanical): 10 fps applies to compressed RAW/JPEG/HEIF; drops to 6 fps for lossless or uncompressed RAW.
- 12Ricoh GR IV, Continuous shooting (mechanical): The review cites 4 fps continuous without specifying shutter type.
- 13Sony RX100 VII, Continuous shooting (mechanical): The 'Hi' burst setting is electronic-shutter only; 10 fps ('Mid') is the fastest mechanical-shutter continuous rate.
- 14Canon EOS R100, Continuous shooting (electronic): The electronic (silent) shutter does not support continuous shooting on this camera.
- 15Sony 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.
- 16Ricoh 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.
- 17Ricoh GR IV, AF subject detection: Only face/eye detection is offered; no animal or vehicle subject recognition is listed.
- 18Sony RX100 VII, AF subject detection: Maker names only human and animal recognition (Eye AF / Real-time Tracking); no bird or vehicle categories are listed.
- 19Sony a7 IV, 4K max frame rate: 4K 60p is only available in Super35mm crop; full-frame 4K tops out at 30p.
- 20Sony RX100 VII, Video codecs: Both XAVC S and AVCHD recording use MPEG-4 AVC/H.264; there is no HEVC/H.265 option.
- 21Sony a7 IV, 4K max frame rate (full width): 4K 60p requires the Super35mm crop; full-width 4K is limited to 30p.
- 22Canon EOS R100, 4K max frame rate (full width): All 4K recording uses a ~1.6x centre crop, so no full-width 4K mode exists.
- 23Sony a7 IV, Raw video recording: No internal or external raw recording; HDMI output tops out at 10-bit 4:2:2.
- 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.
- 25Sony RX100 VII, Log profile support: S-Log2, S-Log3 and HLG log gammas are selectable via Picture Profile presets PP1–PP10.
- 26Sony a7 IV, Video dynamic range (log): Sony's claim for S-Log3 per internal tests; stated as 15+ stops.
- 27Canon 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.
- 28Sony a7 IV, Screen size: Sony rates the panel at 2.95in (3.0-type); most sources round to 3in.

- 34Ricoh GR IV, Memory card slots: Single microSD slot, plus 53 GB internal memory that cannot record to both at once.
- 35Sony a7 IV, Weather sealing: Dust and moisture resistant but not IP-rated; Sony does not guarantee 100% sealing.
- 36Canon EOS R100, Weight: CIPA weight: body with battery and memory card, without lens.
- 37Sony a7 IV, Depth: Sony lists 79.8mm total depth; 69.7mm is measured from front grip to rear monitor.
