  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. 3Sony a7 IV, Native ISO maximum: Native range tops out at ISO 51200; 50-204800 requires expanded ISO settings.
  4. 4Canon EOS R100, Native ISO maximum: ISO 25600 (H) is an expanded setting, not a native sensitivity.
  5. 5Canon 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.
  6. 6Sony a1 II, In-body image stabilization: 8.5 stops is the CIPA centre rating; 7.0 stops at the periphery.
  7. 7Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
  8. 8Canon EOS R100, In-body image stabilization: No in-body stabilization; shake correction relies on IS lenses or Movie Digital IS.
  9. 9Sony a7 IV, Continuous shooting (mechanical): 10 fps applies to compressed RAW/JPEG/HEIF; drops to 6 fps for lossless or uncompressed RAW.
  10. 10Canon EOS R100, Continuous shooting (electronic): The electronic (silent) shutter does not support continuous shooting on this camera.
  11. 11Canon 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.
  12. 12Sony a1 II, Pre-burst capture duration: Pre-capture buffers between 0.03 s and 1 s of frames before full shutter press.
  13. 13Canon EOS R6 Mark III, AF subject detection: Car detection is tuned for racing cars, per Canon.

  17. 17Canon 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.
  18. 18Sony a1 II, 4K max frame rate (full width): Full-width 4K tops out at 59.94p; 4K 100/120p requires a 1.1x crop.
  19. 19Sony a7 IV, 4K max frame rate (full width): 4K 60p requires the Super35mm crop; full-width 4K is limited to 30p.
  20. 20Canon EOS R100, 4K max frame rate (full width): All 4K recording uses a ~1.6x centre crop, so no full-width 4K mode exists.
  21. 21Sony a1 II, Raw video recording: 16-bit RAW video can only be output over HDMI to an external recorder; no internal RAW recording.
  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.

  27. 27Sony a7 IV, Rear screen resolution: 1,036,800 dots; Sony's retail pages round this to 1.03 megadots.
  28. 28Canon 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.
