I have a Pentax K-50 and I'm considering a lens advertised for Pentax KAF cameras. Is a KAF lens compatible with the K-50, and are there any differences between KAF, KAF2, and KAF3 I should be aware of?

Yes. Pentax has the longest history of keeping lens compatibility. Any K-mount lens will work on the K-50. The mount is descried as KAF, KAF2, KAF3 which corresponds to come refinements done over the years but they are still compatible. Wikipedia has an article explaining all the differences.

Yes. A Pentax KAF lens will work on a Pentax K-50. Pentax has kept strong backward compatibility across its K-mount system, and the K-50 uses the same basic K-mount family. Designations like KAF, KAF2, and KAF3 refer to later refinements and feature updates to the mount, but they remain part of the same compatible system.
In general, if a lens is described as Pentax K-mount/KAF, it should mount and function on the K-50. The newer suffixes mainly indicate differences in how autofocus or lens features are implemented, not a completely different mount.
