EOS M camera with L lenses???

got mine with the little zoom 18-55 which is really nice and said to AF faster then the 22... I have used the 70-200 F2.8 MKII on my M.. worked fine and AF speed is ok. Actually the my contax 35-70 F3.4 has been living on the M lately.. so AF speed or lack thereof would be me.

EF converter does not effect aperture BTW..
