I have not processed Nikon D850 raw files for a while, but doing so today, I am impressed by how noisy the D850 seems compared to the Panasonic S1R. Really striking. And with Multi-Shot HighRes mode, it’s like looking at medium format vs APS-C in terms of noise.
I might have to compare the two directly with the same lens to show just how much different/better it is. I suppose I should do so with Sony also.
But no matter what the Multi-Shot HighRes mode of the Panasonic S1R just blows away Sony and Nikon and Canon for both noise and detail.
What to buy
I do one-on-one consulting to go over all the many considerations in choosing a camera system (or computer system). So the following is not a statement of "best" for everyone or even most, but just best for the kind of testing and photography I do.
I relish that Multi-Shot HighRes mode so much that I am willing to look past the issues with the S1R. No other camera can deliver the quality I can get out of the S1R, not yet.
Accordingly, I think my very limited money for cameras is going to have to go with the S1R—just hoping it will drop in price before the loaner has to go back. The image quality in Multi-Shot HighRes mode is just incredible, and I can use all my Zeiss DSLR lenses on it, some of which just are incredible.
Just look at the incredible mirrorless selection of highly credible cameras we now have to choose from! And later this year, presumably Sony will have an A7R IV.
