M42 to K mount permament conversion

for those with a vice and a small drill (and steady hands)

any of your M42 lenses can be permanently converted to sit on your pentax by simply marking of the location of the locking pin (protruding from the body) when the lens its tightly secured, and then drilling a big enough hole in it.

then just take one of your adapters and remove the locking plate from it, violla!

the only caveat is that some M42 lenses are so small in diameter that they bypass the locking pin all together, like a 55mm F1.8 supertak..


however, my recently acquired Jupiter-9 is now a regular K mount just like everything else
