Sigma fp vs Sony A7C II
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 A7C II leads at Approx. 530 shots (Viewfinder) / Approx. 560 shots (LCD monitor) (CIPA standard) vs the fp's 280 still images; 70 minutes continuous.
- Resolution (MP): the A7C II leads at 33 vs the fp's 24.6.
- Weight (body): the fp leads at 422 g vs the A7C II's 514 g.

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.
