Tamron 17-70mm f/2.8 Di III-A VC RXD Lens for Sony E

Spanning a highly versatile zoom range and characterized by its bright design, the Tamron 17-70mm f/2.8 Di III-A VC RXD is a premium everyday lens designed specifically for APS-C-format Sony E-mount mirrorless cameras. Providing a 25.5-105mm full-frame equivalent focal length, this lens seamlessly covers wide-angle to short-telephoto perspectives. Whether you are capturing sweeping landscapes, tight portraits, or daily travel moments, this all-in-one zoom delivers exceptional flexibility.

A standout feature is the fast, constant f/2.8 maximum aperture, which affords consistent brightness throughout the entire zoom range. This allows for superior control over depth of field for beautiful background blur (bokeh) and vastly improves performance in difficult, low-light shooting conditions. Complementing its speed is Tamron's Vibration Compensation (VC) image stabilization system, which effectively minimizes the appearance of camera shake to ensure steady, sharp results during handheld photo and video recording.

Optically, the lens is crafted with 16 elements in 12 groups, incorporating three aspherical elements and two Low Dispersion (LD) elements. These specialized optics work together to correct distortion, chromatic aberrations, and color fringing, resulting in imagery with high sharpness, clarity, and accurate rendering. Furthermore, Tamron's proprietary BBAR (Broad-Band Anti-Reflection) Coating suppresses internal reflections, flare, and ghosting, maximizing contrast when shooting against harsh or backlit lighting.

Benefitting handling and operation, the lens utilizes an RXD (Rapid eXtra-silent stepping Drive) motor, enabling remarkably quick, near-silent autofocus performance that is perfectly suited for both stills and video applications. Built to withstand the rigors of travel and outdoor use, the lens features a moisture-resistant construction and a fluorine-coated front element to repel fingerprints, dirt, and water.
