EF/EF-S Canon Adapter to EF-M Mount

Wheaty214I really enjoy astrophotography and landscape photography, so I'm looking at getting an ultra wide lens like the 11-16mm Tokina f/2.0 or the Rokinon 12mm f/2.0. The thing is, if I want the f/2.0's, I need to find an adapter because they only come in the M Mounts. Otherwise I'll have to get the f/2.8.

Does anyone know of an adapter from EF/EF-S to the old M Mount? I've found the reverse, but nothing that I'm trying to find.

Thanks for the help!

MESKICan't do what you want. Sorry bud. Going to have to go with the f2.8.

CabbyArrantHonestly the 2.8 will be fine for what you want. I have successfully done astrophotography with a 3.5
