You're mixing a few things up. First off, when straight adapted, nothing happens to the focal length. It's still a 135mm. It has the field of view of a 200mm lens in full frame, but it's still 135mm. The speed booster widens the lens and makes it a stop faster. The actual effect is 0.71x. So this turns the 135/2 into a 95mm f/1.4. Once you factor in the crop factor, it behaves close to how it would on full frame with regards to field of view and depth of field. (Actual full frame equivalent would be 142mm), but it's still a 95mm lens at this point as the crop factor doesn't actually do anything to the focal length.
Doesn't the Speed Booster make the FF lens behave like the stated focal length, yet "faster" aperture? So in this case, 135mm and f/1.4? Nice shot btw, So very excited to try out my XE1, but I am waiting on a lens adapter...
