![]() What shows up the ageing A7 design more than anything else, though, is what rival camera makers have done. ![]() (Image credit: Rod Lawton/Digital Camera World) This optional VG-C4EM vertical grip offers duplicate controls for vertical shooting and extended battery life – and should also give the A7R IV better balance with larger lenses. The A7R Mark IV does bring wireless tethered shooting capability, though the large files and limited wireless data bandwidth means you’re still likely to be better off with an old-fashioned cable connection. Sony says its 5-axis in-body stabilisation system has been tuned for this new camera to offer up to 5.5EV compensation, and A7R IV’s Pixel Shift Multi Shooting mode can merge 16-shots made with tiny pixel-shifts between each to produce 240MP images – if you have static subjects, sufficient storage capacity and the required Sony Imaging Edge 2.0 software. Nevertheless, it does feel as if the video capabilities have not really advanced significantly. You can capture full HD at up to 120fps and, arguably, the A7R IV is hardly a video specialist. There’s still no 50/60p 4K video capability, nor 10-bit capture, and if you want the best ‘oversampled’ quality you need to use the cropped Super 35 mode. Video performance gets a boost with the addition of Real-Time AF, but otherwise it does feel as if Sony is resting on its laurels somewhat. The SteadyShot INSIDE system now claims to offer 5.5EV shake compensation. ![]() The A7R Mark IV shoots 4K video, naturally, but doesn't seem to have moved on very far in this area. Sony’s latest AF system brings 567 phase detection AF points covering 74% of the image area (or the entire area in APS-C mode) and both human and animal eye tracking. True, the buffer capacity is restricted to 68 raw files/JPEGS, but it’s also possible to shoot in an APS-C mode that captures 26 megapixel images and with 3x the buffer capacity (claimed). What’s truly impressive is how Sony has managed to maintain a 10fps continuous shooting speed despite the massive increase in the data that’s being captured and processed. That’s an increase in image width and height of 15%.

If you're going to make the most of all this resolution, you'll need to invest in Sony's best G Master lenses too, like the 24-70mm f/2.8.
