Jnanian, yeah, the Pen F/FT are great. I have a Pen F and 3 lens setup. Makes a great travel set. If you are talking about Leica M mount to Pen F adapters, well there is no space to make an adapter that will allow the lens to focus to infinity. The Pen F flange to film distance is 28.95mm and Leica M is 27.8mm. The Pen F will take a variety of SLR lenses but there are no current adapters being made and so adapters for Olympus OM, Nikon F, and M42 mounts command very high prices.
i only have the "normal" ( 38mm 1.8 ? ) lens its nice and i like keeping it simple
the leica lenses i have are screw mount is that m42 ?
i am clueless but enjoying myself even if i have to dream from time to time
oh, forgot to say welcome !
