q&a

DT Lens Design
A more compact, lightweight lens designed specifically for the APS-size CCD imager used in the Sony (alpha) cameras.

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.

Advisory when using DT lenses with full-frame (35mm equivalent) DSLR cameras.
Sony a (alpha) lenses with the Digital Technology (DT) designation are ideal for use on APS-C size DSLR cameras and are not recommended for use with full frame DSLR camera bodies (such as the DSLR-A900). Although DT lenses can be used with full frame cameras, they can only realize a maximum of 11MP image size (when using the DSLR-A900)., and are not guaranteed to provide accurate Auto Exposure performance.
