On a XX or XXX D model, it might not make any speed difference unless yr cam has two separate processing CPUs like 1 ser cams.

The only difference I can see could possibly be for you to control specific AF 'ON' and 'OFF' while tracking the subject with interferences crossing yr main subject while keeping yr shutter pressed half-way to retain continuous metering in possible changing light conditions sonce AE lock is not usually a good thing in daylight type situations where you would probably be shooting the marathon in the morning unless yr positioned at a location where the light is very constant in the shooting zone that the runners will pass through.

Hope this helps some.
