Notes on 25 values — test conditions and caveats
  1. 1Canon EOS R50, Launch price: US RRP at launch as listed by Trusted Reviews; the page does not state whether it is body-only.
  2. 2Sony a7 IV, Native ISO maximum: Native range tops out at ISO 51200; 50-204800 requires expanded ISO settings.
  3. 3Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
  4. 4Canon EOS R50, In-body image stabilization: No in-body stabilisation; shake control relies on lens IS or Movie Digital IS.
  5. 5Sony a7 IV, Continuous shooting (mechanical): 10 fps applies to compressed RAW/JPEG/HEIF; drops to 6 fps for lossless or uncompressed RAW.
  6. 6Canon EOS R50, Pre-burst capture duration: No pre-capture mode appears anywhere in Canon's official R50 specifications, so it is treated as absent.
  7. 7Sony a7 IV, 4K max frame rate: 4K 60p is only available in Super35mm crop; full-frame 4K tops out at 30p.
  8. 8Sony a7 IV, 4K max frame rate (full width): 4K 60p requires the Super35mm crop; full-width 4K is limited to 30p.
  9. 9Sony a7 IV, Raw video recording: No internal or external raw recording; HDMI output tops out at 10-bit 4:2:2.
  10. 10Canon EOS R50, Raw video recording: Canon lists only MP4 recording with H.264 or HEVC; no raw video is offered internally or externally.
  11. 11Canon EOS R50, Video bit depth: Standard Rec.709 recording is 8-bit; 10-bit output requires HDR PQ to be switched on.
  12. 12Canon EOS R50, Log profile support: No Canon Log profile; HDR PQ (a PQ gamma curve) is available instead, which is not a log curve.
  13. 13Sony a7 IV, Video dynamic range (log): Sony's claim for S-Log3 per internal tests; stated as 15+ stops.
  14. 14Sony a7 IV, Screen size: Sony rates the panel at 2.95in (3.0-type); most sources round to 3in.
  15. 15Sony a7 IV, Rear screen resolution: 1,036,800 dots; Sony's retail pages round this to 1.03 megadots.
  16. 16Sony a7 IV, Battery life: 580 shots per charge with the rear LCD; 520 with the EVF.
  17. 17Canon EOS R50, Battery life: CIPA test with the supplied LP-E17 in power-saving mode; viewfinder shooting is rated at about 310 shots.
  18. 18Sony a7 IV, Weather sealing: Dust and moisture resistant but not IP-rated; Sony does not guarantee 100% sealing.
  19. 19Canon EOS R50, Weather sealing: Canon's own spec sheet also lists water/dust resistance as not provided, so treat the body as unsealed.
  20. 20Canon EOS R50, Weight: Black body with battery and card per CIPA; the white version is 376 g with battery and card.
  21. 21Sony a7 IV, Depth: Sony lists 79.8mm total depth; 69.7mm is measured from front grip to rear monitor.
  22. 22Sony a7 IV, USB charging & power delivery: Charging and USB power delivery work only through the USB Type-C port.
  23. 23Canon EOS R50, USB charging & power delivery: USB-C charging works with the supplied LP-E17; unauthenticated third-party batteries may not charge.
  24. 24Canon EOS R50, Minimum operating temperature: Rated operating range is 0–40 °C at up to 85% humidity.
  25. 25Canon EOS R50, Headphone port: Canon's full port list covers USB-C, mic-in, HDMI micro and the shoe only — no headphone jack.

Image Quality and Sensor

The Sony delivers higher resolution with 33 MP and captures more detail in low light thanks to its native ISO maximum of 51,200. It also provides built-in image stabilization rated at 5.5 stops.

In contrast, the Canon relies on a 24.2 MP APS-C sensor with a native ISO maximum of 32,000 and zero stops of in-body stabilization, meaning it depends entirely on lens or digital stabilization.

Video Capabilities

Both models record video using H.264 and HEVC codecs with 10-bit color depth available. The Sony takes the lead for advanced filmmakers by supporting log profiles and reaching 60 fps in 4K, though that higher frame rate applies only with a Super35mm crop.

The Canon limits its 4K recording to 29.97 fps across the full width and omits log profile support entirely, providing HDR PQ instead.

Speed and Autofocus

Action shooters get faster bursts from the Canon, which reaches 12 fps with its mechanical shutter and 15 fps electronically. The Sony trails slightly with 10 fps for both mechanical and electronic modes.

When tracking subjects, both bodies detect humans, animals, and birds, but the Canon adds vehicle detection to its autofocus repertoire.

Handling and Build

At 375 g, the Canon is significantly lighter and smaller than the Sony, making it easier to carry all day. However, the Sony counters with dust and drip resistance, dual memory card slots, a larger battery rated for 580 shots, and a full-size HDMI port with a headphone jack.

The Canon features a single memory card slot, a micro HDMI port, no headphone jack, and an unsealed body with a 440-shot battery life.

The Verdict

Buy the Sony a7 IV if you need professional full-frame video features, dual card slots, and robust weather sealing. Buy the Canon EOS R50 if you want a lightweight, compact setup for casual shooting and faster burst rates.
