Canon EOS R3 vs Canon EOS R8
Every spec below is quoted from the makers' official pages — where a figure isn't published we say so rather than guess. Sizes are drawn at true relative scale from published dimensions, and the bag-fit row is computed against our measured bag catalog.
The 3 biggest published differences
- EVF resolution: the R3 leads at 5,760,000 dots vs the R8's 2.36 million dots (1024x768).
- Weight (body): the R8 leads at 461 g vs the R3's 1015 g.
- Burst — mechanical: the R3 leads at 12 vs the R8's no mechanical first curtain; 6 fps with electronic 1st-curtain shutter.

Spec values are the manufacturers' published figures, compared factually — we don't rank cameras. Fit verdicts are planning estimates from published interior dimensions, not guarantees. See methodology.
