Thanks to all for the warm welcome.
Sirius Glass, what luck, I am an expert on half assed photography and have the prints to prove it!
jnanian, sorry, it's a no go with the LTM too. Same problem as the M mount, not enough room for an adapter that will still let the lens reach infinity.
X. Phot., good one. Still OK to photograph M42 with a M42 mount camera?
