Ebay is recently flooded with EF to EOS M speedboosters.
Made to poorest standards and not having any electronics inside they are probably a step backwards....
But they show it can be done. Why is no real fine optics company jumping on the train to build a quality speedbooster with full lens feature support?
 
Oh snap! Time to buy a used EOS M fast before the rest of the market catches up to the news!

Or wait for a FF mirrorless. Size ain't no argument when you have that 85L dangling off the EF-M adapter. Tried it. Ridiculous.

would a speedbooster also work for EF-S lenses?
or would it shrink the image circle? i don't know how it works...

The speedbooster acts like a magnifying glass, concentrating the image over a smaller area. So, it will shrink the image circle.
