Quality that can capture subtleties
Three aspherical elements, one super ED (Extra-low Dispersion) element, and one ED glass element in a precision optical design achieve prime lens-class resolution and contrast. The basic optical design is unchanged from the original version, offering superb wide-angle image quality with an absolute minimum of distortion.
Aspherical elements boost performance
Aspherical lens elements are more difficult to manufacture than simple spherical types, but when properly designed they can reduce a wide range of optical aberrations to extremely low levels. This lens includes three aspherical elements that contribute to stellar overall optical performance.
Super ED and ED glass cut color aberration
This lens includes one Super ED (Extra-low Dispersion) glass element and one ED glass element that greatly reduce chromatic aberration, particularly at longer focal lengths. Super ED glass provides enhanced compensation for chromatic aberration, particularly at longer focal lengths.
Bright and fast for wide-angle versatility
A bright constant F2.8 maximum aperture throughout the wide-angle zoom range means consistent exposure settings at any focal length as well as improved low-light capability. There's no need to worry about aperture-related exposure variations as you zoom, and you can get great results shooting hand-held indoors or in other dimly lit situations.
Smooth, quiet SSM focusing
The SSM (Super Sonic wave Motor) is a piezoelectric drive system that works with an internal focus mechanism in the Vario-Sonnar® T* 16-35 mm F2.8 ZA SSM II for smooth, silent autofocus with no front element rotation. Its capacity for high torque at low rotational speeds contributes to fast start and stop response as well as precise positioning.
Focus mode switch and hold button
In addition to generally convenient positioning and smooth operation of all controls, this lens includes a focus mode switch and focus hold button on the barrel for extra focusing versatility and control.
Reduced ghosting improves image quality
ZEISS® T* (T-star) coating achieves even greater reduction of ghosting, taking image quality that is already highly regarded to a new level.
Beautiful background bokeh
A 9-blade circular aperture works with this lens's F2.8 maximum aperture to produce beautifully smooth background bokeh with natural highlights when desired. Smooth background defocusing can make the in-focus focus really stand out in images with almost three-dimensional depth.
Dust and moisture resistant
Some of the most exciting images are captured in challenging environments. A dust and moisture resistant design means that the lens will continue to perform reliably in moderately wet or dusty conditions, so you can shoot with confidence wherever those great shots are found.
