Ricoh GR III vs Sony A6400
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 A6400 leads at Approx. 360 shots (Viewfinder) / Approx. 410 shots (LCD monitor) (CIPA standard) vs the GR III's Approx. 200 images (CIPA standard).
- Weight (body): the GR III leads at 257 g vs the A6400's 403 g.
- Format: GR III has APS-C 23.5mm x 15.6mm; A6400 has APS-C type (23.5 x 15.6mm).
