The Sigma 45mm f/2.8 DG DN Contemporary lens is a very nice bit of gear; robustly built and compact and light enough to be easy to carry.

How the Sigma C 45 mm f/2.8 DG DN fits that scenario? Not in a perfect way, to be sure. It is a bit too big, too expensive, and its optical performance is not outstanding. In objective terms it is a well-put-together lens, with just one serious flaw, high vignetting, and a lot of serious assets.

very solid, sealed casing,, excellent image quality in frame centre,, good image quality on the edge of the APS-C sensor,, acceptable image quality on the edge of full frame,, very low lateral chromatic aberration,, slight longitudinal chromatic aberration,, sensible coma correction,, moderate...

not especially accurate autofocus,, high vignetting on full frame which, additionally, decreases slowly on stopping down.

In short, while the Sigma 45mm f/2.8's aperture and focal length specs may not bowl you over, this lens is a magnificent shooter with a unique high-performance profile that can capture images that will make any accomplished photographer smile.
