Hello fellow Pentaxians!
Just finished my adapted Zuiko going by RioRico's guides.
I got this lens and a nice Leitz Tiltall tripod for $20.00 from a thrift shop. Lens was so dirty I just had to submerge it in soap water and then disassemble it all..pretty complex in there, btw..lost the aperture bearing at that.
So I filed the bayonet flags mostly by the left side and also filed down the 2 protuding fins on the back side..and it bayonets pretty smooth, doesnt need to be forced..
Heres my first pic with my K30..handheld , not razor sharp, but nice color rendition for a 40 year old lens..
