Leica M11 vs Sony A7R 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
- Burst — mechanical: the A7R III leads at 10 vs the M11's Continuous - Low Speed (3 fps) / Continuous - High Speed (4.5 fps).
- Resolution (MP): the M11 leads at 60 vs the A7R III's 42.4.
- Battery life (CIPA): the M11 leads at Approx. 700 shots (CIPA Standard, rangefinder mode), up to approx. 1700 shots (Leica adapted shooting cycle) vs the A7R III's Approx. 530 shots (Viewfinder) / approx. 650 shots (LCD monitor).

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.
