Originally posted by Confused I'm probably misreading the interpretation of *this entirely, but could it possibly imply that when using third party lens brands such as Sigma, Tamron etc, that the AUTO or SELECT options somehow become unavailable or automatically disabled ?
Hey, Richard - THANKS for this. This would explain something I've been scratching my head about. If I go out with both the K10D and the K20D, I've probably got the Pentax 16-45 on one and the Sigma 17-70 on the other, and I have been noticing that SOMETIMES the AUTO focus mode seems pretty much stuck on center point focus, while other times it doesn't. Hadn't yet noticed that it was the lenses. I will test this now but I'm grateful for the suggestion.

I'd consult the manual more often but I feel that, for every question it answers, it raises three more in its place.
