Adapter for the NIB Rainbow G12.5mm lens for micro four thirds cameras. Since this lens normally doesn't fit to standard c-mount adapters, I created a custom lens mount, which incorporates threads for focusing. For a 12.5 f1.4 lens it has pretty good sensor coverage :) Highres pics at http://www.flickr.com/photos/p1hde/sets/72157633909043803/If you want to edit the sorucefiles: Threads created with thread library by aubenc (slightly altered), imported to sketchup where the rest is desigend.
