Notes on 38 values — test conditions and caveats
  1. 1Sony a7 IV, Native ISO maximum: Native range tops out at ISO 51200; 50-204800 requires expanded ISO settings.
  2. 2Canon EOS R100, Native ISO maximum: ISO 25600 (H) is an expanded setting, not a native sensitivity.
  3. 3Canon EOS R6 Mark II, Native ISO maximum: ISO 204800 (H) is an expanded setting; the native range tops out at ISO 102400.
  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. 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. 7Canon EOS R6 Mark II, In-body image stabilization: The 8-stop rating combines lens optical IS with in-body IS; results vary by lens.
  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. 9Canon EOS R100, Continuous shooting (electronic): The electronic (silent) shutter does not support continuous shooting on this camera.
  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. 11Canon EOS R6 Mark II, Pre-burst capture duration: Pre-release capture works in RAW burst mode and buffers up to 0.5s of action before full shutter press.
  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 II, Video codecs: Movies record H.264 by default; H.265/HEVC is used when Canon Log 3 or HDR PQ is enabled.
  16. 16Canon 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.
  17. 17Sony a7 IV, 4K max frame rate (full width): 4K 60p requires the Super35mm crop; full-width 4K is limited to 30p.
  18. 18Canon EOS R100, 4K max frame rate (full width): All 4K recording uses a ~1.6x centre crop, so no full-width 4K mode exists.
  19. 19Sony a7 IV, Raw video recording: No internal or external raw recording; HDMI output tops out at 10-bit 4:2:2.
  20. 20Canon EOS R6 Mark II, Raw video recording: 6K ProRes RAW requires an external Atomos Ninja V+ recorder connected over HDMI.
  21. 21Canon EOS R6 Mark II, Video bit depth: Standard profiles record 8-bit 4:2:0; 10-bit 4:2:2 requires Canon Log 3 or HDR PQ.
  22. 22Canon EOS R6 Mark III, Video dynamic range (log): Canon's claim of 15+ stops in its Canon Log profiles, not a lab measurement.
  23. 23Sony a7 IV, Video dynamic range (log): Sony's claim for S-Log3 per internal tests; stated as 15+ stops.
  24. 24Canon 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.
  25. 25Sony a7 IV, Screen size: Sony rates the panel at 2.95in (3.0-type); most sources round to 3in.
  26. 26Sony a7 IV, Rear screen resolution: 1,036,800 dots; Sony's retail pages round this to 1.03 megadots.
  27. 27Canon 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.
  28. 28Sony a7 IV, Battery life: 580 shots per charge with the rear LCD; 520 with the EVF.
  29. 29Canon EOS R6 Mark II, Battery life: 760 shots is the CIPA power-saving rating with the rear LCD; Canon's smooth-mode rating is 580 shots.
  30. 30Sony a7 IV, Weather sealing: Dust and moisture resistant but not IP-rated; Sony does not guarantee 100% sealing.
  31. 31Canon EOS R6 Mark II, Weather sealing: Sealed dust- and water-resistant build, not IP-rated; Canon cautions ingress cannot be fully prevented.
  32. 32Canon EOS R100, Weight: CIPA weight: body with battery and memory card, without lens.
  33. 33Sony a7 IV, Depth: Sony lists 79.8mm total depth; 69.7mm is measured from front grip to rear monitor.
  34. 34Canon 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.
  35. 35Sony a7 IV, USB charging & power delivery: Charging and USB power delivery work only through the USB Type-C port.
  36. 36Canon EOS R100, USB charging & power delivery: The battery must be charged in the external LC-E17E charger; no USB power delivery.
  37. 37Canon EOS R6 Mark II, USB charging & power delivery: In-body USB charging and power supply require Canon's optional PD-E1 USB power adapter.
  38. 38Canon EOS R6 Mark II, Minimum operating temperature: Canon's product manual rates 0–40°C; regional Canon spec sheets list a 2°C minimum.
