Tamron's professional 70-200mm f/2.8 for Sony A-mount — USD motor with Tamron's SP optical quality.
The Tamron SP 70-200mm f/2.8 Di USD (Model A009) for Sony A-mount is a professional full-frame telephoto zoom with USD (Ultrasonic Silent Drive) autofocus. The Sony A-mount version omits Vibration Compensation (VC) — Sony Alpha A-mount bodies provide in-body SteadyShot INSIDE stabilisation, making lens VC redundant. At approximately 1,470g with tripod collar and 77mm filter thread.
The optical design uses 23 elements in 17 groups. Nine aperture blades. The 77mm filter thread. Approximately 1,470g with tripod collar. Minimum focus distance of 1.3m. USD (Ultrasonic Silent Drive) provides fast, quiet AF. No VC — Sony A-mount bodies provide in-body stabilisation. Constant f/2.8 aperture. Full-frame coverage.
The USD motor on the A009 provides fast, quiet AF for sports and event photography at a lower cost than the Tamron 150-600mm or Sony 70-200mm GM equivalents. The absence of VC is specific to the Sony A-mount version — the Canon EF and Nikon F versions include VC stabilisation. On Sony A-mount bodies, the in-body SteadyShot provides equivalent stabilisation benefit regardless of lens-based VC.
On the used market the Tamron SP 70-200mm f/2.8 Di USD Sony A is affordable for a constant f/2.8 professional telephoto zoom. Condition checks: USD AF response, 77mm front element for marks, tripod collar rotation, zoom ring smoothness. No VC on this mount version. Compatible with all Sony A-mount (alpha) bodies.
