It looks neat. Ideally, I would want to have 2 6k cams - one running this full frame speed booster, and the other with the standard 1.5x crop... reason being, I love using some of the APS-C Glass and would hate to see vignetting in the picture at lower focal ranges/wide perspectives.

While with the Metabones, etc, on an MFT Mount, you can easily remove the speedbooster to use your other lenses; it looks like the process is a little more involved here and even if I was brave enough to do it with my own shaky coffee hands, I’d only want to do it once.

The end result does look fantastic though, thanks for giving me a heads up about this — it’s definitely worth a shot if you’re invested in full frame lenses... I love the support for these cameras and how much third party companies are adding to them post OEM.
