I was browsing the forums before posting this and someone asked about making an adapter so I posted there too, but oh well.
I built an adapter for my Nikon lenses that works reasonably well. I just posted a test reel on vimeo here. I don't know what goes into making a metal one. My adapter is made of the lenses plastic rear protective cap + a piece of ABS pipe + the GH1's plastic body cap.
I would like to hear people's opinions/suggestions about it's image quality. I think it's a bit soft, but I don't know if the Sigma 10-20 with a proper adapter is any better, I'd like to hear from someone who used that combo, or even the 43rds version of the lens. The Nikon 50mm 1.4 works decently enough.
Build Summary: I drilled holes in the caps, guesstimated the focus distance by holding the lens to the GH1 and blocking light with a tube of paper, then cut the ABS pipe to that distance, tested the focus distance again with the caps and ABS, trimmed/sanded/tested ABS till it focused to infinity, then glued the pieces together with JB Kwik weld. Did it all in a day, maybe 4-5 hours at most including shopping time.
Couple problems:
-It's not very pretty.
-I couldn't test how flat/parallel the lens is to the sensor after I put the JB epoxy on, so it's not perfectly squared with the sensor- not to a degree where it looks weird though.
-There's no locks on the caps so it doesn't snap to the body of the camera or the lens, this has yet to be a problem but I guess it's possible to bump it till it unscrewed itself, if you pay attention though this won't happen.
-No communication with the camera. Though this is only with high end adapters anyways.
