Designed exclusively for full-frame mirrorless cameras, the lens will be released Dec. 7 and will be available for Sony E-mount and Leica L-Mount. It will list for $1,499.
Dust and splash-proof construction, a high-performance optical stabilizer and an inner zoom mechanism that does not affect barrel length are among its features. It’s also the first Sigma DN zoom lens to be equipped with an aperture ring. In addition to a lightweight lens body, a new, compact tripod collar and foot also help minimize weight, as does a carbon fiber-reinforced plastic lens hood.
Featuring Dual HLA-driven floating focus for fast, accurate AF, the focus lens is driven using a High-response Linear Actuator as the focus actuator, and a floating focus is used to achieve high-speed AF drive. The floating configuration of this lens, in which the two focus groups are driven in opposite directions, reduces the amount of movement of each focus group to about half that of a single-group focus system. The latest OS2 stabilization algorithm achieves image-stabilization performance of 7.5 stops at the wide end and 5.5 stops at the tele end.
