Covering everything from 24mm real 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 four hybrid aspherical elements, resulting in ideal compensation of comatic 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.
*SP: "Super Performance" – a line of high-performance lenses featuring high design specifications. In designing the SP series, the first and foremost priority is put on superior specifications and outstanding performance free from cost restraints. Therefore, SP lenses featuring impressive and innovative designs are concept models among Tamron lenses.
