CanonWatch spotted that video showing a yet not announced Speed Booster adapter for the Canon EOS-M system! On Metabones website you can find NEX and X mount adapters only.
And by the way, Metabones isn’t the only manufacturer offering a “Speed Booster” solution. The Chinese company Mitakon now sold their first “Lens Turbo” adapters on .

I’d like to see a review of the cheaper chinese ones. Do they degrade or soften image in any way? Is the increase in lens speed for real? (e.g. a f2 full frame lens will really behave like f2 on APS-C, instead of behaving like f2.8?)
f2 full frame lens with speed booster will behave like f1.4 on APS-C
I’m probably missing something. Correct me if I’m wrong. At f2, the physical aperture on a 50mm lens is 25mm (50/25=2). But the lens on APS-C acts as if it were a 75mm, with always the same physical aperture, so shouldn’t its “f number” be equivalent to 75/25, i.e. about 3, on APS-C?
And Mitakon also doesn’t offer FD mount!
Hellooooou! It’s the most versatile one!
But I guess they would rather you buy more than one I guess. ;-/
