Sigma's new 15mm f/1.4 DG DN Art diagonal fisheye lens is unique, a little bit weird, and definitely niche. The company knows it won't be a big seller, but that's not why it decided to make it. Sigma made it to prove a point.
It’s not often that I get to review a lens that the world has never seen before. I’ve reviewed plenty of f/1.4 lenses and I’ve reviewed the occasional 15mm fisheye, but a 15mm diagonal fisheye with an f/1.4 maximum aperture is a first for me.
Alongside the Sigma 500mm f/5.6 DG DN OS Sports lens, Sigma has announced the 15mm f/1.4 DG DN Diagonal Fisheye Art. The new lens is the world's first-ever f/1.4 diagonal fisheye for interchangeable lens full-frame cameras.
