Canon is such an odd company sometimes. I know the EOS-M hasn't been very successful in the US but I think they were silly not to release the 11-22/f4-5.6 IS lens here. The biggest problem with their mirrorless offering is a lack of suitable lenses. Yes, they have a great EF adapter and a ton of other lenses in EF mount but they made the EOS-M almost too small for any of them to be well matched. I bought the 11-22 from a dealer in Hong Kong and it is a really impressive little piece of glass. The IS works well and it is sharp even wide open and the price is really very good. Below is a picture of my pup Frankie taken at 11mm to show the distortion caused by such a wide angle. Maybe I'll share a photo at 22mm some time, this little gem can focus really close!
