Sony 16-35mm f/2.8 ZA SSM

The 16-35mm f/2.8 ZA SSM Vario-Sonnar T* Lens from Sony is a professional-grade, bright zoom lens specifically designed for the Sony Alpha SLR series (also compatible with Minolta Maxxum series) DSLR cameras. Carl Zeiss' optical design and anti-flare T* (T-Star) coatings used for this lens help to reduce flare and to increase contrast, in addition to the aspherical, extra-low dispersion, and super extra-low dispersion glass elements

Aperture Range:

f/2.8-22With f/2.8 throughout the zoom range, up to a maximum of f/22, the high quality of this lens means you don't have to sacrifice aperture for higher focal lengths as some lenses do when zooming in.

Extra-Low Dispersion (ED) & Super Extra-Low Dispersion (Super ED) Glass Elements

To reduce chromatic aberrations, most noticeable when zoomed all the way in, the extra-low dispersion elements correct for certain wavelengths of light - producing sharper images with truer colors.
