Vario-Sonnar T* 24-70mm F2.8 ZA SSM II
Prime lens quality in a versatile zoom
The Vario-Sonnar T* 24-70mm F2.8 ZA SSM II employs two aspherical elements and two ED (Extra-low Dispersion) glass elements in a precision optical design for excellent resolution and contrast. The basic optical design is the same as the original version, which is widely regarded as being more like a prime lens than a zoom in terms of image quality.
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 two aspherical elements that contribute to stellar overall optical performance.
ED glass suppresses chromatic aberration
This lens includes two ED (Extra-low Dispersion) glass elements that greatly reduce chromatic aberration, particularly at longer focal lengths. They also contribute to superior contrast across the entire image, even at large aperture settings.
Great results in low light
A bright constant F2.8 maximum aperture throughout the zoom range means consistent exposure settings at any focal length as well as improved low-light capability. There’s no 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* 24-70mm 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.
The Vario-Sonnar T* 24-70mm F2.8 ZA SSM II can focus as close as 34 centimeters for a 0.25 magnification ratio that makes it possible to capture small subjects and details with excellent quality.
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.
