From the golden age of Pentax and my personal collection comes this SMC-M 40mm f2.8 "pancake" lens #5145314 for the K-mount. I believe this was the first "pancake" lens by anyone - but the Konica 40mm may be very close ? It is a 4 element Tessar formula and was very popular at the time. I believe this was released the same time as the MX body - as Pentax was in a shrinking size war with Olympus at the time.
CONDITION: Is EXC + there are no issues cosmetically or functionally. Focus is smoooth and diaphram working properly. Takes 49mm filters and comes with OEM front and rear caps.
$85 shipped to lower 48 U.S. PayPal preferred. Thanks for stopping by PENTAX fans ! .....Larry
