The Tamron 200-500mm f/5-6.3 Di ultra telephoto zoom lens 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 though it covers a range up to 500mm, its design is relatively lightweight and compact. When mounted on an APS-C size digital SLR camera, it provides a focal length equivalent of 760mm for super ultra telephoto imaging.

The optical design of this lens enables you to get as close 8.2' (2.5 m) from your main subject at any focal length, and provides a maximum magnification ratio 1:5 at the 500mm end, allowing for dynamic and impressive pictures of small objects.

This lens sports the detachable Filter Effect Control ring. This allows a filter to be rotated to the desired position with the hood still attached, enabling you to simultaneously perform minute adjustments to a polarizer filter. You can confirm the Polarizing effect through the viewfinder, all while using the hood to prevent harmful light from entering the lens.

Di (Digitally Integrated Design) is a designation Tamron puts on lenses featuring optical systems designed to meet the performance characteristics of digital SLR cameras.
