Notes on 37 values — test conditions and caveats
  1. 1Sony a7 V, High resolution pixel-shift mode: No in-camera pixel shift; Sony's Extended Hi-Res merges burst frames later in its desktop software.
  2. 2Nikon Z6III, High resolution pixel-shift mode: Pixel-shift frames are merged on a computer in NX Studio, not in the camera.
  3. 3Sony a7 V, Native ISO maximum: Refers to standard still image shooting prior to ISO expansion.
  4. 4Sony a7 IV, Native ISO maximum: Native range tops out at ISO 51200; 50-204800 requires expanded ISO settings.
  5. 5Sony a7 V, In-body image stabilization: Measured at the center with an FE 50mm F1.2 GM lens mounted per CIPA 2024 standards with long exposure NR off.
  6. 6Canon 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.
  7. 7Nikon Z6III, In-body image stabilization: CIPA figure measured with the non-VR NIKKOR Z 24-120mm f/4 S at 120mm.
  8. 8Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
  9. 9Sony a7 V, Continuous shooting (mechanical): Maximum continuous shooting speed achieved using mechanical shutter in Hi+ mode.
  10. 10Sony a7 IV, Continuous shooting (mechanical): 10 fps applies to compressed RAW/JPEG/HEIF; drops to 6 fps for lossless or uncompressed RAW.
  11. 11Sony a7 V, Continuous shooting (electronic): Maximum continuous shooting speed achieved using electronic shutter in Hi+ mode.
  12. 12Nikon Z6III, Continuous shooting (electronic): 60 fps is full-resolution JPEG only; Raw bursts top out at 20 fps, and 120 fps uses a DX crop.
  13. 13Canon 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.
  14. 14Nikon Z6III, Pre-burst capture duration: Pre-Release Capture records JPEG only.
  15. 15Canon EOS R6 Mark III, AF subject detection: Car detection is tuned for racing cars, per Canon.
  16. 16Canon EOS R6 Mark III, Max video resolution: 7K is available only in RAW Video mode; standard MP4 recording tops out at 4K.
  17. 17Sony a7 V, 4K max frame rate: Maximum 4K frame rate is available in XAVC HS 4K 4:2:0 10-bit mode.
  18. 18Sony a7 IV, 4K max frame rate: 4K 60p is only available in Super35mm crop; full-frame 4K tops out at 30p.
  19. 19Sony a7 V, 4K max frame rate (full width): 4K 120p needs an APS-C/Super 35 crop; the full sensor width tops out at 4K 60p.
  20. 20Canon 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.
  21. 21Sony a7 IV, 4K max frame rate (full width): 4K 60p requires the Super35mm crop; full-width 4K is limited to 30p.
  22. 22Sony a7 IV, Raw video recording: No internal or external raw recording; HDMI output tops out at 10-bit 4:2:2.
  23. 23Canon EOS R6 Mark III, Video dynamic range (log): Canon's claim of 15+ stops in its Canon Log profiles, not a lab measurement.
  24. 24Nikon Z6III, Video dynamic range (log): Nikon states "13+ stops" for N-Log in H.265 10-bit at ISO 800.
  25. 25Sony a7 IV, Video dynamic range (log): Sony's claim for S-Log3 per internal tests; stated as 15+ stops.
  26. 26Sony a7 V, Viewfinder magnification: Measured with a 50mm lens focused at infinity at -1 m⁻¹.
  27. 27Sony a7 IV, Screen size: Sony rates the panel at 2.95in (3.0-type); most sources round to 3in.
  28. 28Sony a7 IV, Rear screen resolution: 1,036,800 dots; Sony's retail pages round this to 1.03 megadots.
  29. 29Sony a7 V, Battery life: Measured using the LCD monitor under standard CIPA test conditions.
  30. 30Canon 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.
  31. 31Sony a7 IV, Battery life: 580 shots per charge with the rear LCD; 520 with the EVF.
  32. 32Sony a7 IV, Weather sealing: Dust and moisture resistant but not IP-rated; Sony does not guarantee 100% sealing.
  33. 33Sony a7 V, Depth: Overall maximum depth including the viewfinder eyepiece is 82.4 mm.
  34. 34Sony a7 IV, Depth: Sony lists 79.8mm total depth; 69.7mm is measured from front grip to rear monitor.
  35. 35Canon 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.
  36. 36Nikon Z6III, USB charging & power delivery: In-camera charging and USB power need a USB-PD source such as Nikon's EH-8P.
  37. 37Sony a7 IV, USB charging & power delivery: Charging and USB power delivery work only through the USB Type-C port.
