Hi all, I've been absent from the forum for a long time. I've been using a much abused 400D for a the last 5 years and it's on the point of dying permanently. I have the oppertunity to buy an almost new 50D at a good price and it will give me the increased fps I want plus a more rugged body. What I would really like to know from those of you with firsthand experience is how the AF compares between the two models? Is the 50D AF noticeably faster/more accurate? Of course I'd love a 7D, but the money isn't available! Thanks in advance for your views.
