As per title really. I want to upgrade from my old 350D, have a budget of around £400 - £450 after some recent lens purchases. I mostly shoot motorsport mixed with a bit of UE and general randomness. I have been looking at used 40Ds (less than 5000 actuations) and 450Ds. Is there a big advantage of a 40D over the 450D? would you recommend a new 450D over a used 40D? Or would you recommend something else? all comments appreciated!
