Sony A7 IV 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 A7R IV leads at 61.0 vs the A7 IV's 33.
- EVF resolution: the A7R IV leads at 5,760,000 dots (1.3 cm (0.5 type) electronic viewfinder, UXGA OLED) vs the A7 IV's 3,686,400 dots (0.5-type Quad-VGA OLED).
- Weight (body): the A7 IV leads at 658 g vs the A7R IV's 665 g.
