Notes on 32 values — test conditions and caveats
  1. 1Nikon Z 30, Sensor format: DX format is Nikon's name for its APS-C-size sensor (23.5 x 15.7 mm).
  2. 2Sony a7 IV, Native ISO maximum: Native range tops out at ISO 51200; 50-204800 requires expanded ISO settings.
  3. 3Nikon Z 30, Native ISO maximum: Settings above ISO 51200 (102400, 204800) are expanded, not native.
  4. 4Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
  5. 5Sony 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.
  6. 6Nikon Z 30, Aspect ratios: Native DX ratio is 3:2; 1:1 and 16:9 are in-camera crop modes.
  7. 7Sony RX100 VII, Aspect ratios: 4:3, 16:9 and 1:1 sizes are in-camera crop modes over the native 3:2 sensor area.
  8. 8Sony a7 IV, Continuous shooting (mechanical): 10 fps applies to compressed RAW/JPEG/HEIF; drops to 6 fps for lossless or uncompressed RAW.
  9. 9Nikon Z 30, Continuous shooting (mechanical): Nikon's in-house measured maximum; the rate is approximate.
  10. 10Sony RX100 VII, Continuous shooting (mechanical): The 'Hi' burst setting is electronic-shutter only; 10 fps ('Mid') is the fastest mechanical-shutter continuous rate.
  11. 11Sony 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.
  12. 12Sony RX100 VII, AF subject detection: Maker names only human and animal recognition (Eye AF / Real-time Tracking); no bird or vehicle categories are listed.
  13. 13Sony a7 IV, 4K max frame rate: 4K 60p is only available in Super35mm crop; full-frame 4K tops out at 30p.
  14. 14Sony RX100 VII, Video codecs: Both XAVC S and AVCHD recording use MPEG-4 AVC/H.264; there is no HEVC/H.265 option.
  15. 15Sony a7 IV, 4K max frame rate (full width): 4K 60p requires the Super35mm crop; full-width 4K is limited to 30p.
  16. 16Sony a6700, 4K max frame rate (full width): Full-width 4K tops out at 60p; 120p 4K uses a crop.
  17. 17Sony a7 IV, Raw video recording: No internal or external raw recording; HDMI output tops out at 10-bit 4:2:2.
  18. 18Sony RX100 VII, Raw video recording: Sony's movie-format list contains only XAVC S (H.264) and AVCHD; no raw video output is offered.
  19. 19Sony RX100 VII, Log profile support: S-Log2, S-Log3 and HLG log gammas are selectable via Picture Profile presets PP1–PP10.
  20. 20Sony a7 IV, Video dynamic range (log): Sony's claim for S-Log3 per internal tests; stated as 15+ stops.
  21. 21Nikon Z 30, Viewfinder resolution: The Z 30 has no electronic viewfinder; compose on the rear LCD.
  22. 22Sony a7 IV, Screen size: Sony rates the panel at 2.95in (3.0-type); most sources round to 3in.
  23. 23Sony 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.
  24. 24Sony a7 IV, Rear screen resolution: 1,036,800 dots; Sony's retail pages round this to 1.03 megadots.
  25. 25Sony a7 IV, Battery life: 580 shots per charge with the rear LCD; 520 with the EVF.
  26. 26Nikon Z 30, Battery life: Figure is for the EN-EL25 battery; shot count differs with EN-EL25a.
  27. 27Sony RX100 VII, Battery life: 260 shots assume default monitor settings; Sony also lists 310 shots when 'Auto Monitor Off' is set to 2 s.
  28. 28Sony a7 IV, Weather sealing: Dust and moisture resistant but not IP-rated; Sony does not guarantee 100% sealing.
  29. 29Sony a7 IV, Depth: Sony lists 79.8mm total depth; 69.7mm is measured from front grip to rear monitor.
  30. 30Sony a7 IV, USB charging & power delivery: Charging and USB power delivery work only through the USB Type-C port.
  31. 31Nikon Z 30, USB charging & power delivery: In-camera USB charging/power needs Nikon's optional EH-7P or EH-8P adapter.
  32. 32Sony RX100 VII, USB charging & power delivery: In-body USB charging and power supply work over the Multi/Micro-USB (USB 2.0) terminal — not USB-C.
