Canon EOS 90D vs Canon EOS R100
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
- Battery life (CIPA): the 90D leads at 1300 (at 23°C, AE 50%, FE 50%, LP-E6N) vs the R100's 320 (viewfinder shooting, power saving, +23°C, LP-E17).
- Weight (body): the R100 leads at 356 g vs the 90D's 701 g.
- Burst — mechanical: the 90D leads at 10 vs the R100's 6.5.

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.
