I use Mamiya M645 medium format lenses on my ...5DII with a Mirex M645 to EOS tilt-shift adapter, for lenses with focal lengths from 35mm to 150mm.
Me as well, and I concur with Jim that above 150mm it starts to get a bit odd. The tilt at the very least, ceases to perform as you'd like. The shift can go on and on past 150mm. I which MIREX didn't write/print info on the inner surfaces of the adapter, and I also wish they'd try some sort of alternative "flocking" method as the machining they do helps with reflections but it's not really matte.
I asked them about making an adapter without the writing/printing on the inside shift plate and they seemed really sour on it, in part by replying that it doesn't affect the image.
