Sharpness at f2.0 vs f3.2

This a comment for this page on the website
Hello,
I like the RX1 a lot, but center sharpness gets A LOT better when stopping down from f2.0 to f2.8 or f3.2. At 100% view, this is fully field relevant: Details and sharpness at 2.0 are okay, from 3.2 they are brilliant. I must admit to be somewhat disappointed by that. Does this practical view fit to Your lab results (which are somewhat abstract to me), i.e. is that "perfectly normal" or did I get a bad copy ?

Yours sincerely

Martin

Hello Martin,

Thanks for your interest in DxOMark.

You are right but we would not say "a lot", as we measured a slight loss of sharpness at f/2.0 and we did not measure any significant difference between f/2.8 and f/4.
To be convinced you should have a look to the acutance field map.

Best regards,

The DxOMark team
