Wide-angle zoom
Vario-Sonnar T* 16–35mm F2.8 ZA SSM SAL1635Z
Although it is a wide-angle zoom, and an ideal supplement to a high-
performance mid-range zoom, the 16–35mm range of this lens will satisfy
the core focal length requirements of many photographers who shoot
primarily indoors or in the city. At the other end of the spectrum it can
be a great choice for spacious landscapes as well. Regardless of where
or how the SAL1635Z is used, its advanced coated optical path delivers
exceedingly crisp images with striking contrast, without the aberration
and peripheral light falloff that commonly plague wide-angle zooms.
That same superlative quality is maintained throughout the zoom range,
even at the maximum F2.8 aperture.

Mid-range zoom
Vario-Sonnar T* DT 16–80mm F3.5–4.5 ZA SAL1680Z
Because it has been designed specifically for APS-C format cameras,
the SAL1680Z is the lightest and most compact zoom in the Carl Zeiss
lineup. It also offers the greatest zoom range in the lineup, making it a
superb single-lens solution for many APS-C format photographers. Its
35mm equivalent focal length range of 24–120mm may be all you’ll
ever need for day-to-day shooting. And of course it delivers acclaimed
Carl Zeiss optical performance and handling, with image quality that
rivals the best prime lenses at any focal length. Although the maximum
aperture isn’t as large as the 35mm full-frame format lenses in this series,
circular aperture design makes it possible to get creative with beautifully
smooth defocusing effects. The SAL1680Z is quite simply the most versatile,
economical way to experience Carl Zeiss quality on an a series APS-C
format body.
