Tamron 17-70mm f/2.8 Lens Summary
The Tamron 17-70mm f/2.8 Di III-A VC RXD lens for Sony E-mount is the first zoom lens for APS-C Â format cameras from Tamron. With a constant, fast aperture throughout the zoom range and Vibration Compensation, the lens performs well in low lighting conditions, allowing users to hand hold whatever subject they are capturing. An equivalent focal width of 25.5-105mm provides versatile shooting across multiple subjects from landscapes to portraits and everything in between.
The lens features a moisture resistant construction, Fluorine Coating and a common 67mm filter thread, the same as the Tamron series of lenses for full-frame . The 17-70mm is fully compatible with advanced Sony AF functionality, including Fast Hybrid AF and Eye AF.
Lens sharpness is impressive thanks to 16 elements arranged in 12 groups. Special optics include two GM (Glass Moulded Aspherical) lens elements and one hybrid aspherical lens element. Tamron has arranged these to maintain high-resolution performance from edge to edge as required by Sony sensors.
Tamron 17-70mm f/2.8 Lens In More Detail
This Model B070 is the first f/2.8 fast zoom lens in the world for APS-C mirrorless cameras to achieve a 4.1x zoom ratio.
The design delivers excellent resolution from edge-to-edge at 70mm which is a commonly used telephoto zoom focal length.
Additional sophisticated algorithms have been optimised for this model and with the dedicated, independently operating MPU features combine to compensate for vibration most admirably. VC works whether the lens is used with cameras with or without in-body image stabilisation.
When used with Sony’s APS-C mirrorless cameras the zoom lens is nicely balanced and provides a comfortable user experience suited to extended shooting periods.
Lens mount seals and around other critical locations deter moisture and raindrops for a moisture-resistant construction.
The AF drive incorporates a sensor that accurately detects the position of the lens while the RXD motor unit delivers optimised AF control. This achieves fast and accurate AF operation and allows users to maintain tack sharp focus on continuously moving subjects Thanks to the exceedingly quiet AF the lens can be used discreetly in situations which require low noise levels, and for video recording.
Sony compatibility includes
- Fast Hybrid AF
- Eye AF
- Direct Manual Focus (DMF)
- In-camera lens correction (shading, chromatic aberration, distortion)
- Camera-based lens unit firmware updates
