Introduction
The Tamron SP AF 70–200mm f/2.8 Di LD (IF) Macro (Model A001E) is a fast, professional-quality telephoto zoom lens designed for full-frame and APS-C DSLR cameras. It offers a constant f/2.8 aperture, internal focusing, and a notably close 0.95 m minimum focusing distance, making it ideal for portraits, sports, nature, and even semi-macro shooting.
Key Features & Highlights
-
Bright Constant f/2.8 Aperture
Provides excellent low-light capability and depth-of-field control throughout the entire zoom range. -
Internal Focusing (IF)
Focuses without changing the lens length or rotating the front element—great for use with filters and maintaining balance. -
Close Focusing & Macro Capability
Minimum focus distance of just 0.95 m (3.12 ft) across the zoom range, with a maximum magnification of ~0.32× (1:3.1), enabling semi-macro shots without extending the lens. -
High Optical Quality
Features 18 (or 19 for some mount variants) elements in 13–16 groups, including three low-dispersion (LD) elements to reduce chromatic aberration and deliver sharp imagery. -
One-Touch AF/MF Switch (Canon & Nikon)
Convenient sliding clutch to quickly switch between autofocus and manual focus modes—no need to fumble with camera settings. -
Built-in Tripod Collar
Includes a removable, lightweight aluminum tripod mount for stable support—especially helpful given the lens’s weight. -
Quality Build and Accessories
Combines durable plastic and metal in its construction, and ships with a petal-shaped lens hood and padded case for protection.
