Sony SAL-1870 – 18-70mm f/3.5-5.6 Zoom Lens
This superb standard lens for the Alpha DSLR-A100 camera handles the full range of your most common shots, but there’s nothing standard about its advanced optical design. In 35mm equivalent, it covers wide-angle 27mm to 105mm midrange telephoto for snapshots, portraits, interiors and more. An excellent all-around lens for travel.
DT Lens Design
A more compact, lightweight lens designed specifically for the APS-size CCD imager used in the Sony (alpha) DSLR-A100 camera.
Aspherical Lens Elements
To correct visual aberrations at wide-angle setting, enabling a lightweight lens to capture more visually accurate wide-angle shots.
ED (Extra-low Dispersion) Glass
To reduce chromatic aberration at telephoto extension, correcting certain wavelengths of light for sharp, clear images with well defined colors.
Circular Aperture
Because aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.
