I'm looking to do some Portrait/still life/close up photos and I thought this lens looked nice for the price. http://www.wilkinson.co.uk/store/product.php?productid=16308&cat=434&page=1 The thing is, I have a D40 (and im sure you all know of the autofocus business) I know(read: I'm pretty sure) this lens won't autofocus with my camera. That's why im not sure if I should bother buying it or not. Please help? Also, if anyone knows of any similar lenses that will autofocus, could you help me out? Cheers!
