Di II: Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of Tamron's Di products. These lenses are not designed for 35mm film cameras and digital cameras with image sensors larger than 24mm x 16mm.

Introducing the Lightweight and Compact 200-500mm Ultra Telephoto Zoom Lens - Enjoy Dynamic and Impressive Ultra Telephoto Photography This new ultra telephoto zoom lens lets you bring your far away subject up close while compressing the distance between the main subject and the background for professional-looking results. This is a new zoom lens from Tamron that lets you bring your far away subjects up close while compressing the distance between the main subject and the background for professional-looking results. Even while covering up to a 500mm that enables you to take ultra telephoto shots of subjects further than the eye can see, its design is extremely lightweight and compact. When mounted on an APS-C size DSLR camera, it provides a focal length equivalent to a 760mm for super ultra telephoto imaging.

Lightweight and Compact Ultra Telephoto Zoom Lens Covering Up to 500mm - This is a new zoom lens from Tamron that lets you bring your far away subjects up close while compressing the distance between the main subject and the background for professional-looking results. Even while covering up to a 500mm that enables you to take ultra telephoto shots of subjects further than the eye can see, its design is extremely lightweight and compact. When mounted on an APS-C size DSLR camera, it provides a focal length equivalent to a 760mm for super ultra telephoto imaging.

Minimum Object Distance of 2.5m (8.2 ft.) throughout the Range - Tamron's new 200-500mm enables you to get as close as 2.5m (8.2ft.) from your main subject at any focal length and provides a useful maximum magnification ratio of 1:5.0 at the 500mm end, allowing you to take dynamic and impressive pictures of small subjects.

The Detachable Filter Effect Control - The Filter Effect Control is designed to rotate the filter to the desired position with the hood attached, enabling you to simultaneously perform minute adjustments to PL filter compensation. You can confirm the Polarizing effect through the viewfinder, all while using the hood to prevent harmful light from entering the lens.

Lightweight Design - This powerful ultra telephoto zoom lens weighs a mere 43.6 oz. through the use of engineering plastic materials for parts that compose the main barrel that provide strength sufficient for industrial applications, yet offer dimensional stability. The tripod mount, detachable in one touch, is made of magnesium alloy that reconcile light-weight and high rigidity, resulting in enhanced balance and ease of use in hand-held shooting.

Addition to the Di-series - The lens features Tamron's Di (Digitally Integrated Design) optical system to meet the performance characteristics of DSLR cameras as well as film cameras. When mounted on an APSC size DSLR camera, it provides a focal length coverage equivalent to a 310-760mm, covering the ultra telephoto zoom range.

Featuring ap and Clear Images Chromatic aberration is likely to be reproduced in an image as color blur or color shift. On-axis chromatic aberration in particular, that can be a problem in ultra telephoto lenses, causes color blur in the center of an image. This zoom lens features two LD (Low Dispersion) elements made of special glass materials that have low dispersion indices to confine dispersion of spectra, a cause of chromatic aberrations, to the absolute minimum, and provides sharp and clear images.

SP-Series Lens Featuring - High Design Specifications Tamron's SP (Super Performance) series is a line of high performance lenses featuring high design specifications. In designing the SP series lenses, the first and foremost priority is put on superior specifications and outstanding performance free from cost restraint. Therefore, SP lenses featuring impressive and innovative designs are concept models among Tamron lenses.
