Notes on 27 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. 3Canon EOS R100, Native ISO maximum: ISO 25600 (H) is an expanded setting, not a native sensitivity.
  4. 4Nikon Z 30, Native ISO maximum: Settings above ISO 51200 (102400, 204800) are expanded, not native.
  5. 5Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
  6. 6Canon EOS R100, In-body image stabilization: No in-body stabilization; shake correction relies on IS lenses or Movie Digital IS.
  7. 7Nikon Z 30, Aspect ratios: Native DX ratio is 3:2; 1:1 and 16:9 are in-camera crop modes.
  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. 10Canon EOS R100, Continuous shooting (electronic): The electronic (silent) shutter does not support continuous shooting on this camera.
  11. 11Sony a7 IV, 4K max frame rate: 4K 60p is only available in Super35mm crop; full-frame 4K tops out at 30p.
  12. 12Sony a7 IV, 4K max frame rate (full width): 4K 60p requires the Super35mm crop; full-width 4K is limited to 30p.
  13. 13Canon EOS R100, 4K max frame rate (full width): All 4K recording uses a ~1.6x centre crop, so no full-width 4K mode exists.
  14. 14Sony a7 IV, Raw video recording: No internal or external raw recording; HDMI output tops out at 10-bit 4:2:2.
  15. 15Sony a7 IV, Video dynamic range (log): Sony's claim for S-Log3 per internal tests; stated as 15+ stops.
  16. 16Nikon Z 30, Viewfinder resolution: The Z 30 has no electronic viewfinder; compose on the rear LCD.
  17. 17Canon 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.
  18. 18Sony a7 IV, Screen size: Sony rates the panel at 2.95in (3.0-type); most sources round to 3in.
  19. 19Sony a7 IV, Rear screen resolution: 1,036,800 dots; Sony's retail pages round this to 1.03 megadots.
  20. 20Sony a7 IV, Battery life: 580 shots per charge with the rear LCD; 520 with the EVF.
  21. 21Nikon Z 30, Battery life: Figure is for the EN-EL25 battery; shot count differs with EN-EL25a.
  22. 22Sony a7 IV, Weather sealing: Dust and moisture resistant but not IP-rated; Sony does not guarantee 100% sealing.
  23. 23Canon EOS R100, Weight: CIPA weight: body with battery and memory card, without lens.
  24. 24Sony a7 IV, Depth: Sony lists 79.8mm total depth; 69.7mm is measured from front grip to rear monitor.
  25. 25Sony a7 IV, USB charging & power delivery: Charging and USB power delivery work only through the USB Type-C port.
  26. 26Canon EOS R100, USB charging & power delivery: The battery must be charged in the external LC-E17E charger; no USB power delivery.
  27. 27Nikon Z 30, USB charging & power delivery: In-camera USB charging/power needs Nikon's optional EH-7P or EH-8P adapter.
