This is sort of a test of the AF system.it did a good job of zeroing in on the eye. One thing about photographing cats is that there are a lot of diagonal lines in their whiskers,and in the fine fur that surrounds their noses. The original 12MP file shows very slight moire hints,but overall,this photo looked very sharp and contrasty. This is without a doubt,one of the best zooms I have ever shot in terms of rendering very fine detail. My 80-200 AF-ED is probably going up for sale very soon. The fine detail resolution in the original camera file was startling--as good as several prime Nikkors I own.
