Whether that difference will be as large in practice will only be seen after a lot more testing, but the A7R V has a definite technical advantage here. Sony has tweaked its in-body stabilization algorithms in the A7R V to offer up to 8 stops of shake compensation, which is a big step up from the 5.5-stop maximum of the A7 IV. Sony A7 IV: 5-axis IBIS, up to 5.5 stops compensation. ![]() Sony A7R V: 5-axis IBIS, up to 8 stops compensation.The A7R V has the headline specs, the A7 IV has the everyday practicality, but neither stands out against the many good hybrid cameras on the market now. Even here, though, if you want 4K 60p capture, the A7 IV has to switch to a Super35 crop. ![]() The Sony A7 IV does capture full-width 4K oversampled from 7K data, so for 4K video, this is the camera that combines full-width capture and oversampling, where the A7R V does not. The A7R V's sensor basically has too much resolution for video. From 8K to Super35 4K is a bit of a come-down. Both 8K and 4K ‘full width’ capture are actually with a 1.2x crop, and if you want high-quality oversampled 4K you have to switch to a Super35 crop. Neither camera is a video specialist by any means, and despite the Sony A7R V’s headline 8K capture, its resolution actually introduces more compromises. Sony A7 IV: 4K 30p full width, 4K 60p Super35.Sony A7R V: 1.2x crop 8K 24p, 4K 60p, Super35 oversampled 4K. ![]() The Sony A7R V does offer 8K video (with a 1.2x crop) but the A7 IV is better for full-width 4K. The A7R V’s mix of compression formats, image sizes and crop factors makes its raw options more complicated, but also more useful. What’s more, the A7 V can also switch to an APS-C crop and deliver 26MP and 15MP files in this mode too, which could be useful for long-range telephoto shots, for example. On the A7 IV, Medium is 14.2MP and Small is just 8.2MP – far less appealing. On this camera, a Medium raw file is still 26MP and a Small one is 15MP. These size choices make more sense on the A7R V because it has the resolution to handle them.
