Hi all,

A couple of months ago I asked what mount you wanted for Canon's upcoming professional full frame mirrorless camera. The majority voted for EF although it was close. What I want now want to know is what you now think it will be, not what you want it to be.

So, what mount do you THINK it will be?

It will have to be EF-M. Because if it will remain EF/EF-s:

- It will not get the best in performance of MILCs

Can you please elaborate this point?

Every single one of the EF-M lenses is sharper than the EF-S and EF equivalent with rare exceptions.

I don't agree with this statement.  I would put the EF-S 55-250mm STM against the EF-M 50-200mm any day.  Same goes for the EF-S 18-55mm STM f/4.0-5.6 and EF-M 18-55mm.  There isn't a lot of room between the EF-M 11-22mm and EF-S 10-18mm either.  I can't say much about the EF-M 22mm and the EF-S 24mm but it seems they are close also.

I think this is due to less "diffraction" given the shorter flange back distance that mirrorless allows, 18mm vs 44mm for EF/EF-S
