Two New Primes from Sigma are here: a unique Fisheye Art Lens and a lightweight Sports Lens.

Sigma 15mm F1.4 DG DN Diagonal Fisheye Art Lens

A fisheye lens might not be on your list of “must haves,” but Sigma’s new 15mm F1.4 DG DN Diagonal Fisheye Art Lens may pique the interest of astrophotographers as well as landscape and architectural pros. Unique among lenses, this 15mm piece of glass is the world’s first F1.4 diagonal fisheye lens for full-frame mirrorless cameras. Not only is this Sigma lens fast, but it’s exceptionally sharp across its 180-degree field of view. And, importantly, unlike circular fisheye lenses, this one covers the entire imaging sensor for the ultimate in wide-angle images.

Like the Sigma 14mm F1.4 Art Lens, this new model excels for astrophotography. Both lenses offer a number of features to enhance astrophotography capabilities including sagittal coma flare correction that allows for excellent reproduction of bright points of light like stars.

In addition to an AFL button, the 15mm F1.4 is equipped with an MFL switch that locks manual focus by disabling the MF ring. Sheet filters can be placed in the special filter holder at the rear of the lens, and when not in use, stored in the lens cap. The lens also is designed to accommodate a heat strip, preventing the strip from slipping to the edge of the lens barrel and vignetting the shot. Its aperture ring can be “de-clicked” for smooth and quiet video capture. Bundled with a removable Arca-Swiss compatible tripod collar, the lens—which weighs a hefty 48 ounces and measures 4.1 x 6.3 inches—is well balanced when mounted on a tripod.

This dust-and-splash resistant lens will be available in L-Mount and Sony E-Mount in March for $1999.

Sigma 500mm F5.6 DG DN OS Sports Lens

At the other end of the spectrum is Sigma’s new 500mm F5.6 DG DN OS Sports Lens. Thanks to its innovative design and construction, this super telephoto lens can be handheld and measures only 4.2 x 9.2 inches and weighs 48.3 ounces (with its tripod foot).

The lens is equipped with features that provide custom options to meet any photographer’s preferences. For example, you’ll find a focus limiter switch to assist in precise autofocus and a trio of assignable AFL buttons. Its aperture ring can be “de-clicked” for silent and smoother video capture; an aperture ring lock switch is also available. Not surprisingly, the lens is splash-and-dust resistant.

Available in L-Mount and Sony E-Mount and is slated to ship mid-March for $2,999.
