I've only used a couple-three Pentax AF lenses, and only on two or three camera bodies. I've used one Nikon lens and one Canon lens, on their respective bodies. In similar light (daylight, normal contrasts, etc.) I didn't notice that one lens or another was faster than others. Far from a real test, and just an observation based on a small sample. Quieter focusing would be nice, more accurate focusing would be a bonus, better focusing ability in low light and low contrast situations would be wonderful. IMO, auto focus still has a way to go in order to achieve excellent results in all situations.
