And now a question that will reveal my status as a complete novice:
What exactly do the different letters in the Pentax lens designations mean? I've been looking for an explanation on the K mount info page and other places, but not found anything...
I understand the difference between an "M" and "A" lens, of course, and I know an "FA" lens has autofocus. But how about "F"? Or "K"? And are there others?
F lens is the fisrt autofocus serie
K lens is the first bayonet mount serie (note that K is never engraved on the lens !)
