Hi Robert, What body you mount the lenses on can make a big difference in perceived AF speed. The EOS 1v is really fast the EOS 1n is only very fast, but the particular lens models seem to vary in AF speed with different bodies for some reason. For example, an EF 28-105USM mounted on an EOS 1n seems no faster than when mounted on the EOS 5QD and EOS 50E bodies. When I mounted the EF 300 2.8L on the EOS 50E the AF speed was much slower than on the EOS 1n. Maybe the power supply makes a difference as I always use a power booster E1 with good NiCad packs on the EOS 1n bodies I use.
