I need help lads. What mount is this? Front reads sears MC and back has N/AI stamped on it. The dude that gave it to me said it would fit my k1000, but the aperture lever doesn’t even move in the same direction as my Pentax lenses, meaning from being set to f16 and both laid on the table in front of me in the same position, the Pentax tab would be slide one way and the Sears lens the other.
I’m hoping there is some way to adapt the thing because it’s nice clear glass and smoothly functioning, not to mention I need something shorter than my 50mm and 135mm.
