The Sigma 45mm f/2.8 DG DN Contemporary that was launched this year should have been placed in the Art series of Sigma lenses according to optical limits testing. They found a lot to like about the lens in their testing and concluded that:
“In terms of optical performance, the results are pretty impressive. The center quality is very sharp at f/2.8 and the outer image field is pretty good, too. Stopped down to medium aperture settings, the center reaches superb levels and the border/corners improve to very good quality. Lateral CAs are quite negligible. However, the native vignetting, as well as image distortion, are relatively high for such a lens but then Sony’s image auto-correction will take care of this. The technical quality of the bokeh is decent albeit not perfect.
The mechanical quality of the lens is nothing short of outstanding and it puts much higher priced offerings to shame. The all-metal construction looks and feels great….If you are nit-picky you may criticize the partial weather-sealing. The AF is fast and silent…
The biggest flaw of the lens doesn’t relate to its characteristic but to its name – it is just no “Contemporary” lens. It is ARTier than some designated ART lenses in Sigma’s lineup for sure…”
