Curious about the need for a speedbooster on an APS-C sensor - the FOV and DOF for that size is about what we've seen in super 35 for decades of hollywood movies, right?
I get it for having more choices in wides, but running some gorgeous vintage lens through another layer of glass only seems right on a small sensor (4/3 or super 16). Or do some guys desire the Canon-big-sensor look that came about the last few years?
I almost got a BMC micro but factoring in the speedbooster killed the value equation for me...
Metabones makes adapters that have no glass and are not speedboosters as well. Canon EF glass has to have an electronic mount to adjust the iris. So an adapter is a pretty basic need, speedboosting or not if one wants to use Canon EF lenses.
