I have bought several EOS-M's along with my friends that also enjoy this camera. For me, I must really have autofocus so I really enjoy my 85mm 1.8 Canon lens because it seems to just fit the camera. It is just perfect as well as the 50mm 1.8 Canon. Another perfect match seems to be with the EOS-M version of the 18-200mm Tamron lens that is made for this camera. Seems very sharp throughout the zoom range and is very well built just like the EOS-M. I know the lens price is twice what the camera is but since this lens is a native lens for the EOS-M, it is another match made in heaven. This lens is an unsung (unreviewed) hero of a very fine lens. This is my main travel lens when I go on the airplane somewhere and don't want to take my heavy stuff. I also take the F2 22mm for all my inside shots and the 18-200 for everything else (oh also the 40mm pancake and the 50mm 1.8 with the adapter). These make a fine light kit.
