I myself have been photographing for several years with SLRs and for 2 years in the VF with a Canon EOS 5D MK3. I have long searched for a suitable camera for my wife and this with the EOS M found a few months ago. Without hesitation then came the 22 mm pancake this to be a bit more flexible and also to time indemnify tidy. Processing has no equal. Clean, nothing wobbles or creaks, the focus ring runs buttery soft, almost like my L lenses. The image quality is for my purposes more than satisfactory. The AF works fast and above all fail. My 2 camera (Ricoh GR APS-C) has made it very difficult to keep up with the Eos M with the pancake. Who calls a Eos M his own, of the pancake should definitely buy it. Have fun with it.
