I had a bit of a bad experience with Adriano Lolli Como brand with respect to a FD adapter. Instead of a pin or a lug to engage the aperture lever their solution was to force the aperture lever of the lens back and jam it open with a small piece of rubber which inevitably fell out inside the camera body cavity.http://www.adrianololli.com/articolo.asp?ID=3107
This company sells a tilt shift adapter for micro four thirds.
I think the best lens would be a four thirds lens.
I'm not sure though ...
Their PK adapter that I also bought worked well but it was solidly built and quite heavier than necessary.
These adapters were to LM mount and not M4/3. It was also a few years ago and they may have changed their design and construction techniques since.
