Sony A6700 vs Sony A7 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
- EVF magnification: the A6700 leads at Approx. 1.07x (35 mm camera equivalent: Approx. 0.70x) with 50 mm lens at infinity, -1 m-1 vs the A7 III's approx. 0.78x.
- Weight (body): the A6700 leads at 493 g vs the A7 III's 650 g.
- Battery life (CIPA): the A7 III leads at Approx. 610 shots (Viewfinder) / approx. 710 shots (LCD monitor) (CIPA standard) vs the A6700's Approx. 550 shots (Viewfinder) / Approx. 570 shots (LCD monitor) (CIPA standard).
