For the love of GOD! Enlarger lenses go begging!!

All for want of a focusing mount to use with micro 4/3rds. The planet is awash in cheap, unwanted, high-quality enlarger lenses!

Lens Bubbles has what seems like a pretty simple solution to the missing helicoid. He has previously adapted the SK Componon 50 EL and others. I really enjoy following his blog and always find useful information there.

I use an M42 focusing helicoid. Works fine with enlarging lenses.
