I have a Nikon D610 and the Canon EOS M with EF-M 22mm. When I make pictures with my Nikon and as the 24-85 mm 3.5-4.5 and compare them with the images of the EOS M and the above Pancake, I ask myself quite often, what is 24 MP FF and which is 18 MP APS-C , Since Canon is a really good success for !!! A must for any EOS-M owners.
