Ricoh GR III vs Ricoh GR IIIx
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
- In-body stabilisation: the GR IIIx leads at 4 vs the GR III's Sensor-shift shake reduction (SR) (3-axis); 4 steps (CIPA standard).
- Weight (body): the GR III leads at 257 g vs the GR IIIx's 262 g.
- Format: GR III has APS-C 23.5mm x 15.6mm; GR IIIx has APS-C (23.5mm x 15.6mm).

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.
