Two Sony cameras from different generations, yet both with the 61 megapixel sensor, are the a7R IVA and the a7CR. Anyone who wants maximum detail is probably considering both of these cameras carefully! But which one should you get? It really depends on your priorities – I wouldn’t call either camera better than the other, necessarily, but they each have some clear strengths and weaknesses. Here’s what you need to know.
As a side note, you’ll notice that my commentary in this article is taken almost exactly from my Sony a7R IV vs Sony a7CR comparison. That’s because the a7R IV and a7R IVA are essentially interchangeable cameras, with just a few minor differences.

This is a doozy of a comparison, with both sides trading blows. So, I’ll start by clarifying what might be the most important thing to you: image quality is identical on the a7CR and a7R IVA! If you’re choosing between these cameras because you’re a pixel peeper, the only slight advantage is that the a7CR has focus bracketing built-in, while you’ll need to bracket manually on the a7R IVA if you intend to make a focus stack.
The differences come down to other things – most of them stemming from the fact that the a7CR is a smaller, lighter, and newer camera designed with maximum portability in mind. That’s great for some situations, but it also means that the a7CR loses a few nice features in its quest to be as light as possible. Most of all, it only has one memory card slot rather than two – not great if your memory card fails, to say the least. The viewfinder is also noticeably smaller.
On the bright side for the a7CR, it’s easy to see that it’s a newer camera. The Sony a7CR has a more modern processor, better video features, and a fully articulating LCD monitor. All of these things are pretty standard on Sony’s recent cameras, but the a7R IVA is a bit too old to have them.
The biggest of these changes is the processor. The a7CR’s BIONZ XR processor has ai-powered subject-recognition capability that works wonders when photographing fast-moving action, like wildlife photography. Even though the Sony a7CR wouldn’t be my first choice as a wildlife camera, its autofocus system is definitely better than the a7R IVA for subject recognition. (Yes, the a7CR has a smaller buffer and slower frame rate than the a7R IVA, but I think the newer AF system outweighs those concerns.)
Taking all this into account, which one would I recommend? I’d go with the Sony a7CR, except for the issue of memory card slots. It really depends on the type of photography you do, but for some photographers, a single card slot just won’t cut it and is essentially a dealbreaker. The Sony a7CR is otherwise a better value than the Sony a7R IVA, and I’d argue that it’s the more advanced camera overall. Just make sure that you’re comfortable with a single memory card slot if you decide to go that route.
