Hmmm...never heard that before...Don't know which type but all mine are mounted the Voigtlander ones.
Jon is not wrong also, some old LTM Leica lenses like the 50mm f3.5 Elmar, I ever face the infinity catch hitting the LTM adaptor. To use these lenses on M look for LTM adapters with opening slot that clear in way....have fun exploring...
