I made my 35 mm vibrating adapter:)
It's totally DIY, there are only standard parts, and works fine.
I am using EE-S focusing screen and own gg holder created from step-up rings. There are some shots I've done with it. I see there's barrel distortion, but I'm going to put on adapter some correcting glass, which I'm currently looking for. There are also some minor problems, hope I'll fix them.
I see now how difficult is focusing with only small hv20 lcd...
