I have always wondered if I had the resources would I buy LM lenses. Maybe although my love of getting close to things has always made that a bit less appealing. I know there are adapters for that. There are a few small lenses that I have tried that I thought I use as a solo lens. The Olympus Pen-F 38/1.8 fits the bill (as well as being something I can afford). The again, for what I spent on my 3 native lenses I could have probably picked up an M-Rokkor 40/2 and had some left over. I've always wanted to try that lens. Food for thought.
