Tamron 28-75mm f/2.8 Di III RXD is a fast yet compact and lightweight standard zoom lens made for use on a Sony E mount camera with full frame sensor. It also works well on APS-C models.

The lens is weatherproof with internal rubber gaskets and the front element also has a protective fluorine coating that repels rain drops, oil, fingerprints and dirt and makes it easier to clean.

Super quiet AF, ideal for video
The autofocus is powered by a newly developed stepping motor, Rapid eXtra-Silent Stepping Drive (RXD), specially designed for the focus technology used in mirrorless system cameras. It's quick, accurate and super quiet and therefore works great even for video recording.

Tamron 28-75mm f/2.8 Di III RXD also supports Sony's Direct Manual Focus (DMF) and Eye AF functions.

The lens has a minimum focus of only 19 cm in its wide-angle setting, providing an magnification ratio of 1: 2.9. This means that you can capture a stunning close-up of a subject and at the same time show parts of the surroundings in your picture!
 

Advanced optics
Tamron 28-75mm f/2.8 Di III RXD has an advanced optical design with 15 lens elements divided into 12 groups. The arrangement includes elements of both XLD and LD glass with low color dispersion to counter chromatic aberration, as well as one aspheric and two hybrid aspheric elements used to maximize sharpness at all apertures and focal lengths.

The lens is also designed to provide soft and beautiful background blur and is therefor equipped with a nine-blade circular aperture.

In short, a fantastic zoom lens that can be used for everything from landscape and travel photography to portraits and family photos!
