Canon EOS R100 vs Canon EOS RP
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
- Weight (body): the R100 leads at 356 g vs the RP's 485 g.
- EVF magnification: the R100 leads at Approx. 0.95x / 28.0° vs the RP's Approx. 0.70x.
- Burst — mechanical: the R100 leads at 6.5 vs the RP's Max. approx. 5 fps (Max. 4 fps with AF Tracking).

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.
