Leica Q3 vs Sony A7R IV
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 Q3 leads at 60,3 MP (effective); 62,39 MP (total) vs the A7R IV's 61.0.
- Burst — mechanical: the A7R IV leads at Continuous shooting: Hi+: max. 10 fps, Hi: max. 8 fps, Mid: max. 6 fps, Lo: max. 3 fps vs the Q3's Continuous: 2 fps / 4 fps / 7 fps (14 bit), 9 fps / 15 fps (12 bit).
- Battery life (CIPA): the A7R IV leads at Approx. 530 shots (Viewfinder) / approx. 670 shots (LCD monitor) (CIPA standard) vs the Q3's 350 shots (based on CIPA standard).
