Tamron's new 50-300mm VC Lens provides a wide 50mm starting option. The compact size also produces outstanding balance when paired with an APS-C camera for 75-450mm equivalent. The expert arrangement of special lens elements effectively controls aberrations and produces high image quality throughout the entire zoom range. Although it extends to 300mm at the telephoto end, the 50-300mm F4.5-6.3 VC features an extremely compact size with a length of just 150mm (5.9 inch) and a class-leading light weight of 665 grams (23.5 oz). The lens is equipped with a VXD linear motor focus mechanism that delivers excellent quietness and agile autofocus performance, while the VC image stabilization mechanism provides powerful support for every aspect of shooting.
