Interesting focal even used with APS-C sensor, this makes a 64mm portrait lens for example. With a full frame, taking a step back, we have a pretty decent little great angle with an aperture of 2.8 and beautiful "bokeh". Other advantages, weight and also discretion, without forgetting the MAP at 0.30m. Next dive, after just a few images, I am convinced, it looks like L! it stings! Given the worrying financial drift Canon right now we can only welcome the release of this 40mm at this price!
