I?d posted a while ago asking if anybody had any thoughts about filing down 
the threads on a 50mm to allow the focus coupling to travel further on 
lenses that?s close focus was limited to a meter.  Kicking the idea around a 
little, I?ve come up with a modification which will work with any LTM 50mm  
and doesn?t require grinding or altering the lens. It allows close focusing 
to about half a meter (haven?t checked exactly) ? I have before and after 
close focusing images plus instructions here:

I?d been kicking around the idea of getting a voigtlander nokton 1.5 ? the 
LTM ones are cheap, like $400, but the new bayonet mount ones are like $900 
and as far as I can tell, the only significant difference is that the 
bayonet mount ones close focus to .7 meters. 

How many of you still use a LTM mount 50mm?
