I recently purchased a Peleng tilt adapter for my micro 4/3 camera, and I am very pleased with its performance. It converts any M42 SLR lens to a tilt lens that can be tilted eight degrees in any direction. It works best with short focal lengths.
I haven't done a lot with it yet, I had it just for a few days, but I have tried it with those short lenses that I have, a Vivitar 28 mm f/2.5, a Tamron 24-48 mm and a Fujinon 55 mm. So far, it works great.
