Hi.
If I'm understanding the stuff I've read correctly, are these the steps to permanently convert an m42 lens to K-mount?
Buy one of these: (Supposedly it allows focus to infinity)
http://cgi.ebay.com/M42-lens-Pentax-Kx-K7-K20D-adapter-infinite-focusing-/37...#ht_2248wt_877
Then:
1) remove the spring clip on the adapter (I'm not sure where that is, but I can find it)
2) screw it to the lens using a bit of Loctite thread-lock to permanently hold it to the lens
3) mount it to the camera as a K-mount lens
4) mark where the mount locking pin is on the camera
5) remove lens
6) notch lens to match locking pin
I'm looking at using this method with an M42 mirror lens, if that matters.
I would buy a genuine Pentax adapter, but they're getting $45-$65 for them on eBay, which I think is more than a bit nuts.
Thanks,
Bob :-)
