Dpreview compared the four entry level FF cameras and concluded:
Having considered all these factors, and looked at how they apply to different types of photography, it’s difficult to announce a clear winner. It’s certainly not as simple as adding up how many times we’ve recommended each model, since it’s unlikely any one person is going use their camera for every one of these types of shooting.
With that critical caveat, the Sony a7 III remains our generic recommendation, simply because it’s good at just about everything. But it’s a much narrower margin over the Nikon Z6 than when we last pondered this question, and that still doesn’t mean it’ll be the best for you.
Seems like Dpreview didn’t like the S1 that much 🙂
