Sony A7r IV review
Overall the A7r IV is an evolutionary upgrade over its predecessor, but it’s surprising how much a boost in resolution and autofocus performance has broadened the flexibility and appeal of this model in Sony’s lineup, again allowing it to tempt detail fanatics whether their subjects are static or in fast motion. Recommended, although if 42 Megapixels are enough for you, look for bargains on the A7r III.
Sony a7R IV: What you need to know
While the a7R IV helps nudge Sony to the front of the pack, it doesn’t look like as big an upgrade as we’re used to seeing between whole version numbers. Equally, it perpetuates a handful of irritations that have persisted for multiple generations, now.
Hands on: Sony A7R IV review
The A7R IV’s subtle design tweaks make it handle much better than the A7R III before it, and the resolution puts it well ahead of all its full frame mirrorless rivals for megapixels – and yet it has a great ISO range and 15-stop dynamic range too. Sony’s hybrid AF system just keeps on getting better and better, but 4K video stays capped at 30fps, which is mildly disappointing.
