I am not sure how I feel about this lens, yet. It's about 60g lighter than Minolta MD 70-210/4 Macro. It has a zoom lock and a recessed front end, and it's shorter, so it seems that it would be easier to use handheld. The IQ is not bad but I don't know if it's on par with Minolta. The ultimate test will come when I take both to the zoo on a sunny day. For now, just a few teasers from a walk through the local nature preserve. Some of the images were taken wide open and some between 5.6 and 8, but I am not sure which.
