I have had this lens for a month now. For the first 3 weeks, it did not leave the camera. I have to say it does a superb job for the price. For me, it is wide enough at 24mm even on a trip to NYC. It did well during the day, but shined at night when the city comes alive. Also, this lens does perform well in lowlight situations, not as well as the Minolta 50mm f/1.7, but well enough to warrant not having to change lenses.
The downside for some may be the weight. It is quite heavy, but I had no problem using it as a walkaround. Also, at 82mm, filters will be quite expensive. Outside of those 2 issues, the lens is excellent.
