>>2586337I have it, and it is great. Sharpest around f/8, decent speed AF.
I used it for walkaround wildlife photography and it was great (though lack of range and light caused me to eventually upgrade). Whenever I put aside my 600mm lens and hold this one, I can't believe how light it is.
All in all, great lens, had lots of fun using it. I would definitely recommend it.
I can upload couple pictures I've taken with it.
