Astrophotographers were pretty excited about the Sigma 14mm f/1.8 DG HSM Art when it was announced a few months ago. Now that it's shipping, we're starting to see some real world usage from the lens.
Astrophotography fan Tony Liu has posted some sample images of the skies using the Sigma 14mm f/1.8 DG HSM Art to see how well it controls coma.
From FStoppers:
My biggest concern when this lens was announced was if Sigma would keep things the same with coma in the corners of the lens as it had with the 24mm f/1.4 DG HSM ART and 20mm f/1.4 DG HSM ART lenses or if it would return to the optical formula that was closer to the 35mm f/1.4 DG HSM ART lens. The answer is that Sigma seems to have landed oh so short of the 35mm Art perfection, but it is much better than the 20mm and 24mm Art lenses. Read the full story and see the sample images
