Thanks for the quick response! Ok, it's starting to make sense now. But would using a normal M43 Speedbooster with a .71 reducer give almost an exact 1x crop to Super 35? I just find it easier to think in Super 35 focal lengths, which is why I'm asking :P
Aside from the cropping/math question, I noticed in the post Daniel Peters' test with just a generic focal reducer looked great! Is the Metabones Speedbooster the only way to go or would something like a Mitakon Lens Turbo do the trick as well and not mess up the IQ too much?
