Rokkor 135mm MC f/3.5 to EOS mount

[Gambit]

Hi everyone,

Has anyone completed a 135mm Rokkor to EOS conversion.

I am about to embark with the use of a Pentax K mount to EOS AF confirm adaptor. It looks like a really simple job.

Remove the metal ring as pictured below



Drill screw mounting hole through both the metal ring and the adaptor and then mount, as pictured below:


Place on lens and tighten up:


Is it as asy as that?? am i missing something will i get infinity focus?

Thanks

UPDATE:
Well i have completed the above and mounted a Pentax K mount EOS adaptor onto the Rokkor, i dont get infinity focus, so i plan on shaving down the adaptor to get the lens closer to my APS-C sensor.

Fingers crossed it works, anyone got some feedback for me?
Cheers

I don't know for the 135 but for the 58 my experience was more like this

thanks for that, had a look at those sites, the 135mm rokkor requires slightly different approach, i'll grind it down when i get access to a good vice, and see where it takes me.
