Hey all

So I found an m42 to Pentax K mount adapter that had used before. I also recently saw some used Leica screw mount lenses (m42 I think) that look really enticing.

I've read about the loss of infinity focus so am aware of that. However, curious as to whether there are any other issues I should be aware of before putting Leica (voigtlander) screw mount lenses on my Pentax slr?
