Fujifilm X-Pro3 vs Ricoh GR III
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 X-Pro3 leads at 26.1 millions pixels vs the GR III's Approx. 24.24 megapixels (effective).
- Weight (body): the GR III leads at 257 g vs the X-Pro3's 497 g.
- Battery life (CIPA): the X-Pro3 leads at Approx. 370 / 440 frames (EVF / OVF Normal Mode) vs the GR III's Approx. 200 images (CIPA standard).

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.
