Fast-Aperture Standard Zoom. The Tamron 28-75mm f/2.8 Di III VXD G2’s wide-to-portrait range and f/2.8 maximum wide-open aperture make it great for portrait, wedding, and event photography. Its bright maximum aperture gives you excellent depth-of-field control and consistent brightness throughout the zoom range. Using an APS-C camera? This lens will give you 42-112.5mm equivalent focal length.

Advanced Optical Design. The fifteen-group/seventeen-element optical formula includes four low-dispersion elements and three glass-molded aspherical elements to give you sharp, high-contrast images across the image plane. Each lens element has a BBAR-G2 coating that combats ghosting, internal reflections, and flare while helping maintain sharpness and color fidelity even in strong light.

VXD Linear-Motor Autofocus System. The 28-75mm’s VXD linear-motor autofocus system tracks even the most fast-moving subjects quickly, accurately, quietly, and smoothly, making it ideal for still and video use. This lens is compatible with Sony’s Direct Manual Focus function and Eye AF on cameras with those features, and there’s also full-time manual-focus override for even greater precision.

Durable Construction. You can use this lens in inclement conditions thanks to its moisture-resistant build. The front element’s fluorine coating protects against smearing and debris.
