Does 3rd Party APS-C lens work with the EF to M43 Metabone Speed Booster?
I have a Sigma 30mm F1.4 DC and I want to buy a Tokina 11-16mm but I don't know if they will work with the EF to M43 Speed Booster so I can attach them to a GH4. I heard recently that Canon doesn't license out EF-S so then do the 3rd party lens use EF?
Also has anyone tried it and where can I find info about Canon not licensing out EF-S.
