Sigma was teasing a lens announcement for PhotoPlus 2017, and today they (sort of) delivered. The company has announced development of the upcoming Sigma 16mm F1.4 DC DN | Contemporary—a compact, high-speed, wide-angle lens designed for Micro Four Thirds (MFT) and Sony APS-C E-Mount cameras. (Note: this lens is designed for crop sensors, and will produce vignetting on full-frame cameras.)

The company is calling this, "the large-diameter wide-angle lens for which mirrorless camera users have been waiting," and also claiming it's the world's first lens for Sony APS-C E-Mount to pair a 24mm (equivalent) focal length with a bright F1.4 aperture.

The lens follows in the footsteps of Sigma's 30mm F1.4 DC DN | Contemporary, which was released in 2016 and attempted to marry "F1.4 brightness with top-level optical performance" for APS-C and MFT shooters. The goal was to create a lens for crop sensor (DC) mirrorless cameras (DN) that combined a fast aperture with "top-notch optical performance."

In the upcoming 16mm lens, Sigma will achieve this by using an optical design featuring 16 lens elements in 13 groups, a stepping motor for smooth autofocus performance, and a dust- and splash-proof mount.

No word yet on when this lens will be released or how much it will cost when it is, but Sigma did reveal that the 16mm is the second of three lenses it intends to release as part of the DC DN | Contemporary line. The first was the 30mm F1.4, the second the 16mm F1.4, and the third will be an as yet unspecified "telephoto lens" that some believe will be a 50mm F1.4 DC DN | Contemporary, although that's still just speculation at this point.

Development of SIGMA 16mm F1.4 DC DN | Contemporary

The SIGMA Corporation is pleased to announce the development of a new high-performance, large-diameter wide-angle lens, SIGMA 16mm F1.4 DC DN | Contemporary.

This is the world’s first interchangeable lens for mirrorless Sony E-mount cameras in the APS-C format to offer a 24mm focal length (35mm equivalent) and F1.4 brightness. This is the large-diameter wide-angle lens for which mirrorless camera users have been waiting.

With an optical system that rivals that of interchangeable lenses for full-size SLRs, the lens features a wide variety of high-tech optical elements. SIGMA has crafted a lens that leverages optical aberration minimization via the in-camera digital correction. This lens effectively minimizes optical aberrations and offers superb resolution at wide-open aperture and throughout the aperture range. The optical design and stepping motor deliver smooth autofocus during video shooting, while the mount features special sealing creating a dust- and splash-proof design.

Release date and price: TBD
Accessory: Petal type lens hood (LH716-01)
Corresponding AF mounts: Sony E-mount and Micro Four Thirds
