I'd be surprised if a faster lens doesn't help low light autofocus performance. However, I have no data to back that up. Although I rarely use autofocus lenses, I'd be interested in any real test results.
No real test results, but I have to agree with Joe on this one.
I don't use zooms much, and never in low light, most of the time the lenses I have on my istD are f/2 and faster. My experience with the AF in low light is pretty dismal.
In my case, I think a slower lens would only make the AF performance worse than the useless that it already is.
