Sony doesn’t want the Alpha 7R IV to be thought of solely in terms of resolution, but a 61MP sensor is bound to grab the headlines. It beats its full-frame rivals by some margin, and re-establishes Sony as a front-runner in a full-frame mirrorless camera market that’s become very busy.
But the A7R IV is not just about resolution. It has a very rounded balance of overall image quality and versatility, combining its ultra-highresolution with 10fps continuous shooting capability and a buffer that can sustain this for up to 7 seconds. Sony’s epic hybrid AF technology takes another step forward too, with 567 phase-detection AF points spread across 74% of the image area and 325 contrast AF points. It now offers Real-Time AF tracking in its movie mode, too.
And just to drive home the resolution point once more, the Alpha 7R IV has a Pixel Shift Multi Shooting mode than can combine four images for full-colour data for each pixel (avoiding the demosaicing interpolation process cameras normally use) or 16 images with sub-pixel movements to create 240-megapixel photographs.
