1 out of 10 points and not recommendedGood portraitSlow and shallow depth of view
The lens stops down to f/4.8 when focusing at 1:1. It is therefore too slow to shoot macro of live objects such as the fish in an aquarium.reviewed September 1st, 2007 (purchased for $800)
When at 1:1, the effective focal length decreases significantly. Thus, the lens' auto focus often produces blur image when viewed at 100% magnification.
While the lens is good for portrait, it is supposed to be a macro lens. As such, it is a terrible macro lens for living object such as a free moving fish.
