In the previous post, I made a comparison of the Z7 and the D5 in extreme low light. I used AF-S, and the Z7 pictures weren’t a sharp as the D5 ones. So I’m repeating the test using manual focusing. If you look at Bill Claff’s photographic dynamic range numbers, the D5 does better than… [Read More]
