I caved into the fire sale - bought the whole kit (EOS M, 22, 18-55, and 90EX) from 1saleaday yesterday. I was a bit disappointed to read through the manual and see the burst speed was only high with EF/EF-S lenses and that the focus was by wire on the M lenses, but I can live with that. I love the fact that it has almost the same features and menus as the EOS bodies and I'm excited to use it in place of my old Panasonic LX-5 with it's crappy lever zoom and lousy performance above ISO800.
I was wondering how many of you are actually using the adapter. It looks like it's really awkward to use it with any of the L lenses and I'd like to know how many actually use it.
