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

Spanning a flexible everyday zoom range and built around a bright constant aperture, the Tamron 17-70mm f/2.8 Di III-A VC RXD stands out as a 25.5–105mm-equivalent lens designed for APS-C Sony E-mount cameras. Its wide-to-short-tele coverage makes it perfect for daily shooting needs, while the fast f/2.8 aperture maintains consistent brightness and offers refined depth-of-field control in challenging lighting. Enhanced optical engineering, featuring precision-molded aspherical and low-dispersion elements, delivers high clarity, sharp detail, and accurate color reproduction. Tamron’s BBAR coating further boosts contrast by minimizing flare and ghosting when working in strong backlight or harsh illumination.

Its constant f/2.8 aperture behaves like an anchor of brightness, offering dependable low-light performance and control over depth of field. Behind the glass, precision-tuned aspherical and low-dispersion elements keep images crisp and clean, while Tamron’s BBAR coating quietly shields your frames from flare and ghosting when light misbehaves.

To steady the view, the built-in Vibration Compensation system calms the subtle tremors of handheld shooting, especially in dim conditions or while recording video. Focusing is driven by an RXD stepping motor, delivering swift, smooth, almost whisper-quiet autofocus with the option to take manual control at any moment. With a minimum focusing distance of just 7.5 inches, it also leans into close-range creativity. Finally, the exterior is sealed with moisture-resistant construction, and the front element wears a fluorine coat that shrugs off fingerprints, dust, and smudges, making the lens ready for unpredictable weather and long shooting days.
