positive:- REALLY sharp
- nice contrast
- good macro/portrait focal length for APS-C
- focus limiter is very useful on both ends
negative:- lens hood I guess, don't see why they couldn't have used a "normal" one
comment:I've only had this about a month, but it's quickly become one of my very favorite lenses. I wouldn't hesitate to call it the sharpest lens I own, it is sharp even at f2.8. I also find it to be quite versatile. AF can be a bit of an adventure, as with any macro lens, but the focus limiter helps tremendously -- allowing you to limit focus to either side of .55m. that allows you to lock it in on the short end for macro shooting, or the long end for portraits and such, so it doesn't have to hunt through the whole range.

70mm seems to be a great focal length for aps-c. good length for macro without getting too close. 100mm lenses seem to me to be too telephoto on aps-c to have much use beyond macro work, whereas 70mm (which translates to 105mm on film) makes for a much more useful portrait lens.

I really like this one a lot!
