A very good lens though it can't perform miracles and I have not been able to use it hand held, I need to reest it on something. I think I made the correct call in buying it vs the 100-400mm zoom, I think I'd always have the zoom at 400mm and the prime lens is cheaper and better at this. The auto focus mainly works well. I have been using it to photograph birds.
This lens is great. Fast focus and very good picture. A pity no IS ,so have to support lens on tripod or on something.
