Notes on 27 values — test conditions and caveats
  1. 1Sony a1 II, Release date: Announced 19 November 2024; first retail availability was December 2024.
  2. 2Sony a1 II, High resolution pixel-shift mode: 4- or 16-shot pixel shift composites are merged with Sony's Imaging Edge Desktop PC software.
  3. 3Canon EOS R100, Native ISO maximum: ISO 25600 (H) is an expanded setting, not a native sensitivity.
  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 a1 II, In-body image stabilization: 8.5 stops is the CIPA centre rating; 7.0 stops at the periphery.
  6. 6Nikon 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.
  7. 7Canon EOS R100, In-body image stabilization: No in-body stabilization; shake correction relies on IS lenses or Movie Digital IS.
  8. 8Canon EOS R100, Continuous shooting (electronic): The electronic (silent) shutter does not support continuous shooting on this camera.
  9. 9Canon 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.
  10. 10Sony a1 II, Pre-burst capture duration: Pre-capture buffers between 0.03 s and 1 s of frames before full shutter press.
  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 a1 II, 4K max frame rate: 4K 100p/120p recording uses a 1.1x crop.
  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 a1 II, 4K max frame rate (full width): Full-width 4K tops out at 59.94p; 4K 100/120p requires a 1.1x crop.
  17. 17Canon EOS R100, 4K max frame rate (full width): All 4K recording uses a ~1.6x centre crop, so no full-width 4K mode exists.
  18. 18Sony a1 II, Raw video recording: 16-bit RAW video can only be output over HDMI to an external recorder; no internal RAW recording.
  19. 19Canon EOS R6 Mark III, Video dynamic range (log): Canon's claim of 15+ stops in its Canon Log profiles, not a lab measurement.
  20. 20Canon 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.
  21. 21Canon 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.
  22. 22Sony a1 II, Battery life: CIPA rating is 520 shots per charge on the rear LCD; 420 shots with the viewfinder.
  23. 23Sony a1 II, Weather sealing: Sony specifies dust- and moisture-resistant sealing; no formal IP rating is published.
  24. 24Canon EOS R100, Weight: CIPA weight: body with battery and memory card, without lens.
  25. 25Sony a1 II, Depth: Sony also lists 72.8 mm depth measured from grip to monitor, excluding the grip protrusion.
  26. 26Canon 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.
  27. 27Canon EOS R100, USB charging & power delivery: The battery must be charged in the external LC-E17E charger; no USB power delivery.
