Full-Frame Coverage. The Tamron 28-300mm f/3.5-6.3 Di PZD for Sony works with full-frame Sony A-mount DSLRs and crop-frame APS-C DSLRs.

Piezo Drive Autofocus Motor. The PZD motor provides fast, nearly silent performance. You have full-time manual-focus override for fine tuning, and an internal-focusing unit that ensures the lens remains the same physical size and doesn’t rotate.
High-Quality Optics. The fifteen-group/nineteen-element optical formula includes a barrage of low-dispersion, aspherical, and refractive elements that ensures images are sharp throughout the zoom range with minimal distortion and aberrations.
High-Quality Build. This lens’s moisture-resistant construction allows shooting in less-than-spectacular conditions, while its new build style includes linear grid patterns on the rubber zoom and focus rings.
