Sigma 50mm f1.4 HSM DG

Just a quick test for now. Sigma have recently made some more amazing lenses. Their ART series are meant to be well worth considering. Below, I am using the new f1.4 50mm HSM DG lens. This one is for Canon, which I chose after reviews rather than the Canon version.

I did use a flash for this picture, indoors, hence some of the reflectance from the light. See below for a 100% crop.
This is at f1.4.
