Originally posted by fractal Well it depends on the length you want, but Pentax is not all that well known for its awesome performance in sports photography but in any case for an AF long zoom you will pay for it anyway. I do not own it myself but have heard very good things about the DA 50-135mm.
Oh boy here I go getting way off track. I think it would be great if someone built really solid AF zoom with a range of 135-350mm , f4 , full frame , superior IQ and a price tag around $500.
Back to the original discussion: other than for sports/ action/ "from the hip" shots MF works just fine for me and if my images are OOF I can only blame myself. The other side of that is that when the image is just right I get to take all the credit.
