The sharpness at maximum aperture is good, though not perfect, and the autofocus is tolerable or satisfactory for moving subjects when motionless motives.
In terms of autofocus be seen that the camera will quickly through the open shutter to focus, as the kit zoom.
The depth of field is really exciting, and every owner of this prime lens is getting caught, always to vary often the bokeh around.
Canon with the EOS-M plus 22mm lens satisfies my desire for a very compact, universal and in terms of performance convincing camera definitely, and even if both EOS-M and the pancake is not perfect, it's me, given the fantastic processing and choice of materials and the super prize giving only possible 5 stars on camera and this lens.
As long as Canon developed such successful each coming lens, I forgive them the fact that it comes just so sluggish with the EF-M series.
After all, now a bright fixed focal length in the range of 45 mm for the EF-M mount, and I was overjoyed!
