Okay, tested this out for you -- I placed two objects about four inches apart in depth, set the aperture to f/4 using an aperture disk and bent the Lensbaby so both objects showed focus peaking on my X-Pro1, and kept the Lensbaby in the same position with both the the speedbooster (Metabones Ultra Leica R to X-mount) and a regular adapter, using the fine focus ring to maximize the displayed focus peaking for each image. Camera was set to ISO 800, 1/125 to make the comparison demonstrate the stop gain. The images are the JPEGs produced by the camera (auto white balance, 100%DR, Provia/Standard film simulation, all settings at zero). Adapter: Speedbooster: If there are any other specific comparisons you'd like I'm happy to try them out, bearing in mind that I've never used a Lensbaby before today and don't really know what I'm doing with it

Metabones states in their whitepaper (p14) that tilt-shift lenses should work on theirs at least: I've not actually tried it though. I think a friend of mine has a Lensbaby 3G that will work on my speedbooster -- if so I'll give it a shot next week and report back.
