Pentax 645 Lens Overview
These lenses are designed specifically for Pentax's line of medium format cameras. They can be adapted onto K-mount DSLRs via an adapter, but this is typically not convenient as 645 lenses are much larger physically than a corresponding K-Mount lenses.

Series overview:
-"A" lenses are manual focus (1980's)
-"FA" lenses are autofocus (1990's)
-"DA" and "DFA" lenses are optimized for digital and most feature silent autofocus and weather sealing.

The lenses in this category all have wide angles of view.
