You know that is not surprising. I would think that it would focus somewhere
near the hyperfocal distance of the lens wide open because that would be the
maximum contrast point. And that is of course much nearer than infinity.

The problems relate to focussing on distant objects and shooting wide
open - this is not something which is called for, so normally goes
unnoticed until or unless tested specifically. Compare with manual
focus on a distant object and you will probably find that the AF has
focussed in front of the object. Well documented on dpreview and I
think pretty much everyone found to their surprise that it was evident,
but the conclusion was that under normal shooting conditions it is not
that significant.

Would be well worth testing on a film body too. It might
just be the
AF system in the *istD which is often said to have such focussing
innacuracies with fast lenses (like the FA 50 1.4 for
example). There
might be nothing wrong with the lens either...
I use a FA 50 1.4 with the *istD and have had no problems
Kind regards
