Video: Sigma 15mm f/1.4 DG DN Diagonal Fisheye | Art Lens Astrophotography Review

Watch the Lonely Speck video review of the world’s fastest full-frame fisheye lens.

Fisheye lenses are something that I’m very familiar with using. I have always had at least one fisheye lens in my tool kit for the last decade as they’re excellent tools for landscape astrophotography.

With the 15mm f/1.4 Art, Sigma has made the a fisheye lens like never before. It’s the fastest fisheye lens with its f/1.4 aperture, making it a full two stops brighter than any other fisheye lens that I’ve used before. It’s also the first ever autofocus fisheye lens for Sony E or Leica L mount cameras. See what it’s like to shoot with this lens in the video below:
