just bought the lens, love the colors, focusing is fast especially with the limited on 3m. Best thing is how light it is compared to the 2.8 versions, wouldnt mind carrying this around all day.
the only thing i dont like is the limited zoom range, for birds 200mm on a crop body isnt enough, for me, most of the time, a 100-400 would have worked much better i guess, but for the price its great.
at 200mm i expected some softness wide open compared to a stop or two down but from 100%crops theres not much difference that i can make out. The bigger issue is correct focusing at 200mm and my old XT doesnt seem to be doing a really good job at that.
If you can afford the IS version definitely get that, i couldn't so i got this...
