Thanks again guys. I always preach to focus on the eyes and strive to achieve this. Very difficult when the subject is less than a mm in size, the eyes are in the order of tenths or hundredths of a mm, and the depth of field is less than a mm too. Oh, and it's a moving target and I'm at 5:1 magnification hand-held. That's mostly about luck and shooting lots to get a few keepers.
