This is an old enlarger lens that I acquired from a friend of mine. It has a 30mm thread mount. I found a 30mm to 39mm LTM adapter ring. Then mounted that into a LTM to m4/3 adapter. Then I purchased a set of cheap extension tubes. I used a combination of a 28mm and 14mm to get me a distance where I can resolve onto the sensor. All of this works out to be a nice macro solution for me. I am sure no one else will ever post examples in this thread. I just thought it would be nice to post in the Showcase to show what is possible with these odd, old lenses.
