The SMC [K] lenses are sometimes lumped into the SMC-M lenses. Even
thought some of the M lenses such as the SMC-M 135mm f3.5 and the SMC
135mm f3.5 are very different in size weiight and optical formula. The
K lenses are often quite a bit rarer than the equivalent M lenses. The
A lenses are also often rarer than the M version, quite asside from the
fact that the A lenses are often more desirable for their exposure
automation capabilities.

The so called "K series" lenses were the first batch of

Ah, that clarifies it, J.C. Are such lenses still common? I don't recall seeing
any, but just having learned how they would be identified I may simply not have
noticed them.
