Tamron lenses with IF?
I was just reading the Tamron site and noticed that a few lenses are listed with IF (internal focusing). Does this mean they are similar to Nikkor AF-S lenses and will AF on the D40? I haven't seen them on any compatibility lists, so I'm assuming no but want to double check. If not, what exactly is Tamron's IF?
