Following up on my Nikon D800 diffraction discussion, I’ve started a Nikon D4 review section, in which I show a Nikon D4 aperture series from f/2 through f/16 and how diffraction affects per-pixel quality.
Should make an interesting perspective relative to the Nikon D800 results.
I don’t have a Nikon D4 for testing yet; this series was shot incidentally during the course of my Nikon D800 vs Leica S2 comparison. My impression is that its quality is outstanding, which is not to say better than the D800 downsampled to D4 resolution.
Check in-stock status of the D800 and D4 on my Nikon gear page.
