Tamron 70-200mm f/2.8 Di LD (IF) Macro AF Lens for Sony A

The Tamron 70-200mm f/2.8 Di LD (IF) Macro AF is a third-party telephoto zoom lens mounting via Sony A-mount, covering a range well-suited for portraiture, sports, and event photography. The constant f/2.8 maximum aperture is maintained throughout the zoom range, providing consistent light transmission and strong background separation. LD (Low Dispersion) glass elements are incorporated into the optical design to reduce chromatic aberration and maintain contrast across the frame. The internal focusing (IF) system keeps the overall lens length constant during autofocus operation. The lens offers a macro capability with a closer-than-typical minimum focus distance for its class, achieving a maximum magnification of 1:3.9. As a third-party lens, autofocus performance is dependent on the Sony A-mount body in use, and compatibility with newer Sony Alpha A-mount bodies should be verified prior to purchase.
