ONE OF A KIND: Review of the Sigma 15mm F1.4 DG DN Diagonal Fisheye

Sigma has just released a truly unique lens for astrophotography in the Sigma 15mm F1.4 DG DN Diagonal Fisheye | Art. In this video, I review the lens and compare it to the Sigma 14mm F1.4 DG DN | Art, what I called the 'milky way champ' just last year.
