Pentax Thursday #5 June 25 2020

Pentax K5 IIs; Pentax 77mm f1.8

Taken with Zenit Automat, a Soviet-made K-mount SLR. MC Oberon-11K 200mm f/2.8, Fujicolor 100.

 

Of course the original Pentax lens mount was the M42x1 introduced on the Contax-S>Pentacon>Praktica, When Praktica decided to go to a new bayonet mount, it was expected that they might adopt the K mount, to repay the favor, so to speak. Almost, but not actually compatible :

 

Here is a Prakticar 28mm f/2.8 B-mount image just for fun on a Jenaflex (rebranded Praktica B).

Here is the lens and camera

Thank you all for your responses and contributions. Hopefully interest will grow over the months, as restrictions ease and we can get back to 'normal' !
