Canon EOS R3 vs Canon EOS R5
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
- Resolution (MP): the R5 leads at 45 vs the R3's 24.1.
- Burst — electronic: the R3 leads at 30 vs the R5's 20 fps (electronic shutter).
- Weight (body): the R5 leads at 738 g vs the R3's 1015 g.
