Nikon D3x happier
As I mentioned a few days ago, Nikon turned around my D3x in record time.
Preliminary field shots suggest that the issue I suspected might now be gone, but I have to do the tedious work of checking this rigorously—only then am I prepared to publish my comparisons with the Zeiss ZF 21/2.8 Distagon in Zeiss ZF Lenses. PITA.
