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 launched in 2012 as Tamron's professional constant-aperture telephoto zoom for Sony A-mount. The SP (Super Performance) designation and USD (Ultrasonic Silent Drive) motor indicate Tamron's premium tier for this workhorse focal range.
Optically good — sharp in the centre throughout the range with respectable edge performance. The constant f/2.8 aperture provides consistent exposure and subject separation. USD motor is fast and quiet. No VC (Vibration Compensation) on this A-mount version — relies on Sony's in-body stabilisation.
Sony A-mount with 77mm filter thread. Weighs approximately 1500g — heavy. No weather sealing. Full-frame coverage. Minimum focus distance 130cm. Tripod collar included. Moisture-resistant construction. SP build quality with metal barrel sections.
Available used at mid-range prices. A-mount is discontinued, limiting this lens's future utility. Adapts to Sony E-mount via LA-EA adapters but native FE lenses are better. Good for existing A-mount users who need a fast telephoto zoom. Check USD motor operation — should be silent.
