The lens has absolutely terrible purple fringing, the worst I've ever seen. Fairly soft focus as well. For the price it isn't bad I suppose, but I'd look at other offerings such as the Sigma...I have no experience with the Sigma but am tempted to order it and sell this one. This lens is usable, it does focus with a D40 and is very inexpensive, but not sharp enough for me nor can I accept the purple fringing.
