There's more than one way to get a lens on a camera it shouldn't naturally fit, particularly when adaptation has to go beyond mere lens mount disparity and extends all the way to major sensor size differences. Of course, in approximately none such case does the adapter getting the job done actually widen field of view, improve clarity and sharpness, and increase exposure levels by up to one full stop. In fact, to expect as much (and all in one device) would seem to equate to madness -- especially if such a device supports electronic lens control. This is not the short and skinny of the new Tom Cruise sci-fi/action film, but that of the Metabones Speed Booster. The adapter not only mounts your Canon full frame 50mm f/1.8 lens, for instance, to your Sony FS100 -- but also turns it into a sharper 35mm f/1.2 in the process.
