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. • Weight (approx): 860 g • Dimensions (Dia. x L): 83 x 114 mm • Max. magnification ratio: 0.24x Contrast (%) Contrast (%) 48 Contrast (%) Contrast (%) A mode, 1/50 sec., F8, -0.3 EV, ISO 200, Daylight white balance, B/W Creative Style; Photo: Kentaro Fukuda Mid-range zoom Vario-Sonnar T* DT 16-80mm F3.5-4.5 ZA SAL1680Z Aspherical lens At 16 mm - Open 100 80 60 40 20 Contrast (%) At 16 mm - F8 100 80 60 40 20 0 4 8 12 16 20 Distance from center of image (mm) 0 4 8 12 16 20 Distance from center of image (mm) At 80 mm - Open 100 80 60 40 20 Contrast (%) At 80 mm - F8 100 80 60 40 20 0 4 8 12 16 20 Distance from center of image (mm) 0 4 8 12 16 20 Distance from center of image (mm) Two aspherical elements for outstanding image quality at all apertures Carl Zeiss T* coating effectively controls flare and glare Outstanding sharpness and contrast at all focal lengths Circular aperture for attractive defocusing Compact, lightweight high-performance zoom 35mm equivalent focal length: 24-120mm 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.
