The Tamron 17-70mm F/2.8 Di III-A VC RXD is a compact, lightweight zoom designed specifically for Sony APS-C mirrorless cameras. It delivers a constant f/2.8 aperture across the entire zoom range, covering wide-angle to short-tele focal lengths that suit landscapes, architecture, portraits and close-up work.

Key uses and benefits

This lens aims to be an all-rounder you can carry every day. Use it for:

• Wide-angle landscape and architecture photography at 17mm
• Portraits and short-tele work up to 70mm
• Close-up and near-macro subjects thanks to a close focus distance
• Both stills and video, with optical stabilization optimized for video shooting

Optics and close-focusing performance

The optical design contains multiple specialized elements to maintain sharpness and attractive background rendering. The lens achieves high-resolution performance across the frame and produces creamy bokeh with a nine-blade aperture. A short minimum focus distance allows close shooting down to 0.19 m, making the lens suitable for macro-style images as well as general-purpose use.

Stabilization and autofocus

Tamron equips this lens with VC (Vibration Compensation) and a dedicated MPU that handles vibration compensation. The VC implementation is optimized for video and uses AI technology to improve performance when recording motion. Autofocus is driven by an RXD stepping motor that provides smooth, fast AF suitable for both photo and video. The lens is compatible with many camera-specific features and functions, including Fast Hybrid AF and Eye AF.

Build quality and weather resistance

The lens features moisture-resistant construction and a Fluorine coating that provide additional protection for use in challenging conditions. It is compact and lightweight by design, making it easy to carry during travel or long shoots.

Additional notable points

• The lens achieves a 4.1× zoom ratio, a notable figure for a high-speed f/2.8 zoom designed for APS-C mirrorless cameras.
• It shares a 67 mm filter size with other Tamron lenses for Sony E, simplifying the use of filters across multiple lenses.
