Optimal Aperture on D3s

This page examines optical performance on the 12-megapixel Nikon D3s: the practical implications of the choice of aperture. The second (good) sample of the 70-200VR2 was used.

Aperture f/2.8 is definitely not optimal (based on much field shooting), showing results from very good to marginal, depending on focal length and focus distance. This page explores where the gains occur across the aperture range, from f/2.8 through f/8 at infinity focus.

While the 24MP Nikon D3x would show more detail, the same differences will readily be observed on either camera; this I can say for much experience with both. We’re looking for the gross behavior: smearing at the edges and corners as well as outright blur.
