Notes on 22 values — test conditions and caveats
  1. 1Sony a1 II, Release date: Announced 19 November 2024; first retail availability was December 2024.
  2. 2Canon EOS R50, Launch price: US RRP at launch as listed by Trusted Reviews; the page does not state whether it is body-only.
  3. 3Sony a1 II, High resolution pixel-shift mode: 4- or 16-shot pixel shift composites are merged with Sony's Imaging Edge Desktop PC software.
  4. 4Sony a1 II, In-body image stabilization: 8.5 stops is the CIPA centre rating; 7.0 stops at the periphery.
  5. 5Canon EOS R50, In-body image stabilization: No in-body stabilisation; shake control relies on lens IS or Movie Digital IS.
  6. 6Sony a1 II, Pre-burst capture duration: Pre-capture buffers between 0.03 s and 1 s of frames before full shutter press.
  7. 7Canon EOS R50, Pre-burst capture duration: No pre-capture mode appears anywhere in Canon's official R50 specifications, so it is treated as absent.
  8. 8Sony a1 II, 4K max frame rate: 4K 100p/120p recording uses a 1.1x crop.
  9. 9Sony a1 II, 4K max frame rate (full width): Full-width 4K tops out at 59.94p; 4K 100/120p requires a 1.1x crop.
  10. 10Sony a1 II, Raw video recording: 16-bit RAW video can only be output over HDMI to an external recorder; no internal RAW recording.
  11. 11Canon EOS R50, Raw video recording: Canon lists only MP4 recording with H.264 or HEVC; no raw video is offered internally or externally.
  12. 12Canon EOS R50, Video bit depth: Standard Rec.709 recording is 8-bit; 10-bit output requires HDR PQ to be switched on.
  13. 13Canon EOS R50, Log profile support: No Canon Log profile; HDR PQ (a PQ gamma curve) is available instead, which is not a log curve.
  14. 14Sony a1 II, Battery life: CIPA rating is 520 shots per charge on the rear LCD; 420 shots with the viewfinder.
  15. 15Canon EOS R50, Battery life: CIPA test with the supplied LP-E17 in power-saving mode; viewfinder shooting is rated at about 310 shots.
  16. 16Sony a1 II, Weather sealing: Sony specifies dust- and moisture-resistant sealing; no formal IP rating is published.
  17. 17Canon EOS R50, Weather sealing: Canon's own spec sheet also lists water/dust resistance as not provided, so treat the body as unsealed.
  18. 18Canon EOS R50, Weight: Black body with battery and card per CIPA; the white version is 376 g with battery and card.
  19. 19Sony a1 II, Depth: Sony also lists 72.8 mm depth measured from grip to monitor, excluding the grip protrusion.
  20. 20Canon EOS R50, USB charging & power delivery: USB-C charging works with the supplied LP-E17; unauthenticated third-party batteries may not charge.
  21. 21Canon EOS R50, Minimum operating temperature: Rated operating range is 0–40 °C at up to 85% humidity.
  22. 22Canon EOS R50, Headphone port: Canon's full port list covers USB-C, mic-in, HDMI micro and the shoe only — no headphone jack.
