Tamron's A-mount full-frame superzoom — 28-300mm with PZD motor for Sony Alpha system.
The Tamron 28-300mm f/3.5-6.3 Di PZD launched in 2014 as a full-frame superzoom for Sony A-mount. The PZD (Piezoelectric Drive) motor provides quieter AF than body-driven screw. It covers 28-300mm — the ultimate one-lens solution.
Optically acceptable for a superzoom — sharp at mid-focal lengths with expected softness at extremes. PZD motor is faster and quieter than body-driven AF. No VC stabilisation — relies on body SteadyShot. Full-frame coverage.
Sony A-mount with 67mm filter thread. Approximately 540g — moderate for the range. Moisture-resistant construction. PZD motor. Full-frame coverage. Minimum focus distance approximately 49cm.
Available used at budget prices. A-mount is discontinued. The PZD motor is an improvement over body-driven AF. For A-mount users wanting maximum range in one lens. The VC version for Canon/Nikon added stabilisation.
