Tamron 70-300 f/4.5-6.3 RXD Di III

A small and compact model by the standards of telephoto cameras with a variable "fork" of focal lengths of 70-300 mm. Available for Sony E-mount full-frame mirrorless cameras. The lens has a low "floating" f / 4.5-6.3 aperture and is intended for photography at long distances. Inside it is an RXD (Rapid eXtra-silent stepping Drive) autofocus drive, whose work is aimed at lightning-fast and error-free autofocus.

The optical design of the Tamron 70-300 f/4.5-6.3 RXD Di III features 15 elements in 10 groups using an LD lens to suppress chromatic aberrations. To eliminate glare and reflections, BBAR's proprietary anti-reflective coating is applied to the surface of the lenses. The diaphragm of the model is 9-bladed. With a body length of 148 mm, the telephoto weighs only slightly more than half a kilogram (545 g). There is no stabilization system on board the lens, so when using it, you often need the help of a tripod.
