Tamron 17-70mm f/2.8 Di III-A VC RXD Lens (Sony E Mount)
The Tamron 17-70mm f/2.8 Di III-A VC RXD is a groundbreaking standard zoom designed specifically for APS-C Sony E-mount mirrorless cameras. Combining a versatile 25.5-105mm equivalent focal range with a bright, constant f/2.8 aperture, this lens is a powerful “all-in-one” solution for everything from expansive landscapes to intimate portraits. It is the first high-speed zoom lens for APS-C mirrorless cameras to achieve a 4.1x zoom ratio while maintaining elite optical performance and stabilization.
Constant f/2.8 Aperture and Advanced Optics
Fixed f/2.8 Maximum Aperture: Unlike standard kit lenses, this lens maintains its bright f/2.8 aperture throughout the entire zoom range. This provides consistent exposure, excellent low-light performance, and a shallow depth of field for professional subject isolation.
Corrected, High-Resolution Imagery: The optical design features two molded glass aspherical elements, one hybrid aspherical element, and two Low Dispersion (LD) elements. These specialized optics work together to virtually eliminate chromatic aberrations and distortion for edge-to-edge sharpness.
BBAR Coating: Tamron’s Broad-Band Anti-Reflection coating suppresses internal reflections, flare, and ghosting, ensuring high contrast even when shooting in backlit or harsh lighting environments.
Stabilization and Precision Handling
VC (Vibration Compensation): The integrated image stabilization system effectively minimizes camera shake. This is a critical feature for handheld shooting in dim light and ensures smooth, steady footage for videographers.
RXD Stepping Motor: The Rapid eXtra-silent stepping Drive (RXD) provides incredibly fast and near-silent autofocus. It is fully compatible with Sony’s advanced camera features like Fast Hybrid AF and Eye AF, making it ideal for both stills and video.
Close-Focus Capability: With a minimum focusing distance of just 7.5″ at the wide end, this lens allows for dramatic close-up photography with a maximum magnification ratio of 1:4.8.
Built for the Elements
Weather-Resistant Construction: Moisture-resistant seals are located throughout the lens barrel, providing peace of mind when shooting in inclement weather or humid environments.
Fluorine Front Coating: The front lens element features a protective fluorine coating that repels water, oil, and dust, making it easy to wipe away fingerprints and smudges.
Rounded 9-Blade Diaphragm: Produces a soft, pleasing bokeh that enhances out-of-focus highlights and adds a cinematic quality to your imagery.
