Yes I know their is a countless number of other threads on this but i still have a few questions. Ive heard great things about the d40 but also have heard that it can hold back potential after time. Ive heard that it does not have a built in AF motor, what does this mean and what does this hold back. Ive also been looking into the Canon Rebel series and they seem very promising though itt costs a little more. Suggestsions and what does the AF motor affect. Also does anyone know an affordable camera site that is reliable.
