Frank like the 60 micro very well only down side is working distance. Need to get very close to subject for micro shot. Need to get a mono-pod to get steady shots or be lucky when set up with tripod and bee's show up. Friend had a Nikon 105 mm at work and let me try it out that gave a better working distance but camera shake was more pronounced this was under fluorescent lights and could have been one of my more unsteady days. Also its a good all round lens (nice substitute for the 18-70 mm kit lens) gives sharp images.
Only on the third month of having the D70 and lens so this is rookie opinion.
It may be a rookie opinion, but the 60 macro is what Ron Reznick shot with all day at the local botanical gardens when he was here for a class last year. Must be a pretty good lens if Ron has it in his bag. 8)
