Sigma has announced two new lenses. First up, a long, relatively low-budget full-frame telephoto, the Sigma 500mm f/5.6 DG DN OS Sports (buy here). I say relatively because it’s not cheap, but half the price of the old 500mm f/4 for DSLRs (buy here).
The other goes in completely the opposite direction. It’s the Sigma 15mm F1.4 DG DN Diagonal Fisheye Art (buy here). This one’s a biggy. Sigma says it’s the world’s first full-frame fisheye lens with a wide f/1.4 aperture.
Sigma 500mm f/5.6 DG DN OS Sports
First up, the big telephoto. The Sigma 500mm f/5.6 DG DN OS Sports offers a nice long focal length for sports and wildlife shooters. It features all-new optics and Sigma’s new OS2 optical stabilisation algorithm. This brings up to 5 stops of stabilisation power to the lens.
As a long lens with an f/5.6 aperture, it’s much lighter than its f/4 counterparts. This makes it much easier to handhold than wider aperture lenses. This saving is also reflected in the price, with the new lens costing half that of Sigma’s older 500mm f/4 Sports lens for DSLRs.

Sigma 15mm F1.4 DG DN Diagonal Fisheye Art
The Sigma 15mm F1.4 DG DN Diagonal Fisheye Art is an interesting lens indeed. Sigma says it’s the world’s first full-frame fisheye lens with a maximum aperture of f/1.4. This makes it ideally suited to low-light applications.
Despite the super wide aperture, it should still offer a very deep depth of field once you focus more than a few feet from the front of the lens. It’s just the nature of ultra-wide rectilinear and fisheye lenses. Sigma says it also offers very high detail-resolving power, even shot wide open.
