The price/peformance ratio of this lens is amazing. This would be something that would make the EOS-M a much better system camera with a quite good ultrawide at a bargain price. This lens outperforms a perennial favorite of mine the Tokina 11-16mm in terms of IQ I think. DXOmark review here: DxOMark - Canon EF-M 11-22mm f4-5.6 IS STM lens review: good all round performer Not sure why Canon doesn't sell it in the US though. Sheesh.
