Press text:

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
* The appearance and specifications are subject to change without notice.

소니 E마운트용으로 개발된 렌즈입니다. 거기에 마포마운트도 지원해주는거고요...
APS-C기준 35미리 환산 24mm/F1.4입니다.

다른건 모르겠고, 방진방적은 맘에 드네요. GH5에도 작아보이지 않는데 A6500에 물리면... 장난 아닐 듯....
