Notes on 30 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. 4Canon EOS R6 Mark III, In-body image stabilization: 8.5 stops is Canon's best-case center rating with certain RF lenses; peripheral and other lenses see less, down to 7.5 stops.
  5. 5Nikon 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.
  6. 6Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
  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 R6 Mark III, Pre-burst capture duration: Works only in the 40 fps electronic-shutter mode; Canon states it as up to 20 frames.
  11. 11Nikon Z9, Pre-burst capture duration: Pre-Release Capture is only available in the C30 and C120 high-speed frame capture modes.
  12. 12Canon EOS R6 Mark III, AF subject detection: Car detection is tuned for racing cars, per Canon.
  13. 13Canon EOS R6 Mark III, Max video resolution: 7K is available only in RAW Video mode; standard MP4 recording tops out at 4K.
  14. 14Sony a7 IV, 4K max frame rate: 4K 60p is only available in Super35mm crop; full-frame 4K tops out at 30p.
  15. 15Canon EOS R6 Mark III, 4K max frame rate (full width): 4K 120p uses the full width but is not oversampled; oversampled 4K tops out at 60p.
  16. 16Sony a7 IV, 4K max frame rate (full width): 4K 60p requires the Super35mm crop; full-width 4K is limited to 30p.
  17. 17Sony a7 IV, Raw video recording: No internal or external raw recording; HDMI output tops out at 10-bit 4:2:2.
  18. 18Canon EOS R6 Mark III, Video dynamic range (log): Canon's claim of 15+ stops in its Canon Log profiles, not a lab measurement.
  19. 19Sony a7 IV, Video dynamic range (log): Sony's claim for S-Log3 per internal tests; stated as 15+ stops.
  20. 20Nikon Z 30, Viewfinder resolution: The Z 30 has no electronic viewfinder; compose on the rear LCD.
  21. 21Sony a7 IV, Screen size: Sony rates the panel at 2.95in (3.0-type); most sources round to 3in.
  22. 22Sony a7 IV, Rear screen resolution: 1,036,800 dots; Sony's retail pages round this to 1.03 megadots.
  23. 23Canon EOS R6 Mark III, Battery life: 620 shots is CIPA's rating using the rear LCD (not the viewfinder) at 23°C; real-world results vary.
  24. 24Sony a7 IV, Battery life: 580 shots per charge with the rear LCD; 520 with the EVF.
  25. 25Nikon Z 30, Battery life: Figure is for the EN-EL25 battery; shot count differs with EN-EL25a.
  26. 26Sony a7 IV, Weather sealing: Dust and moisture resistant but not IP-rated; Sony does not guarantee 100% sealing.
  27. 27Sony a7 IV, Depth: Sony lists 79.8mm total depth; 69.7mm is measured from front grip to rear monitor.
  28. 28Canon EOS R6 Mark III, USB charging & power delivery: USB-C charging and power need a capable USB-PD source such as Canon's PD-E2; not every power bank works.
  29. 29Sony a7 IV, USB charging & power delivery: Charging and USB power delivery work only through the USB Type-C port.
  30. 30Nikon Z 30, USB charging & power delivery: In-camera USB charging/power needs Nikon's optional EH-7P or EH-8P adapter.
