K 45-125/4

General Description

The newer of the two lenses has an additional distance scale (engraved on the focus ring) which is applicable when a close-up lens is attached. Furthermore, the dedicated lens case for that lens has a separate compartment for a close-up lens. I do not know if the close-up lens is a dedicated one and if was sold separately or with the lens itself…
