- 1. Design (absolutely no backlash, the zoom ring is moderately tight, all switches are fixed exactly) 2. Fairly fast focusing with my Nikon D5000 3. Picture on 4+ without any flaws 4. Virtually silent focus motor
- 1. The hole at a wide angle is not 2.8 2. A hole at a long angle could be smaller (4.5) 3. No ringing sharpness. Although of course this is far from a macro lens
