Sony SAL-18200 Specification Guide

Internal Focusing System

Internal lens elements move when focusing, so the overall length does not change -- creating a 

lens that focuses more quickly and doesn’t change balance. 

Aspherical Lens Elements

Three aspherical elements correct visual aberrations more effectively across the entire zoom 

range and help reduce weight.

ED (Extra-low Dispersion) Glass

Two ED Glass lenses minimize flare and greatly reduce chromatic aberration, giving you sharp, 

clear shots even at full telephoto extension.

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 α (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.

This is a perfect all-in-one standard zoom lens that brings you closer to 

your subject for use with Sony® α (alpha) DSLR cameras.  With 

superior all-in-one lens performance for everyday shooting, its 35mm-

equivalent range of 27mm wide-angle to 300mm telephoto excels at 

capturing faraway subjects, sports events, dramatic landscapes and 

intimate close-up views.
