Tamron AF SP 24-135mm AD Aspherical (IF)

Covering everything from 24mm wideangle through to 135mm telephoto, this lightweight compact lens represents a new departure in the high power zoom lens concept with outstanding optical performance characteristics of the SP Series.

The optical system incorporates a new AD (Anomalous Dispersion) glass element and as many as four hybrid spherical elements, resulting in ideal compensation of chromatic aberration and astigmatism. The MOD (Minimum Object Distance) of the lens is 40cm over the entire zoom range. The 135mm telephoto achieves a maximum magnification ratio of 1:3.3, making macro photography possible. A zoom lock feature is included for enhanced portability.

* The Zoom-lock mechanism is a feature that turns practicality into necessity for photographers who depend on the zoom lens. With frequent use as a standard zoom, the capability of the lens to lock at the most compact zoom setting is a convenient addition that prevents undesired barrel extension while carrying the camera/lens outfit around.
