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.

I agree, the 85L 1.2 Grapefruit is a heavy add on for an M... but a 70-200 4.0 IS that behaves like 70 200 2.8 IS for half the money and half the weight?

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.

I assume that crop factor lenses from Sigma and Tamron will show dark corner, Canon EFS might even collide with the glas in the speedbooster

the 70-200 f4 would be the lens fuji already has: 50-140 f2.8, which would be awesome and actually make me buy one :D

apparently viltrox had a prototype at photokina :)
https://www.dpreview.com/forums/post/61724031

rumored launch date is end of the month with a price of ~180$
this plus a 50 1.8 makes for a half priced alternative to the recent 32 1.4 :p

the adapter is already listed on the chinese page of viltrox, but not the english one...

Edit 20.10: it's listed also on the english website :)
