The new SP70-200mm F/2.8 G2 (Model A025) telephoto lens reimagines the highly acclaimed Model A009 with enhanced optical performance, improved VC (Vibration Compensation), faster AF speed and accuracy, and shortened MOD (Minimum Object Distance) for greater flexibility. What’s more, compatibility with Tamron teleconverters provides additional focal length. In keeping with the SP series’ innovative technology, the lens is designed to be durable, flexible and resilient enough to rise to any occasion.

High resolution meets beautiful bokeh
Every aspect of the SP 70-200mm F/2.8 G2 (Model A025) zoom has been improved, providing high image quality and enhanced bokeh throughout. Optical design features include XLD (eXtra Low Dispersion) and LD (Low Dispersion) glass to eliminate chromatic aberrations across the entire zoom range, ensuring optimum resolution― even at the edges. eBAND Coating designed exclusively for this new zoom offers superior anti- reflection properties, greatly minimizing flare and ghosting. And refined bokeh provides spectacular background effects from nearly any angle.

MOD reduced to 0.95m
Improvements to the new SP 70-200mm F/2.8 G2 extend well into the lens barrel. Tamron has reduced the MOD from 1.3m (50.7 in) in our older model to 0.95m (37.4 in), allowing a maximum magnification ratio of 1:6.1. The shorter MOD, coupled with the superb optical performance of this new zoom, allows you to significantly broaden your range of expression.

Accuracy in action
The USD (Ultrasonic Silent Drive) ring-type motor, along with two high-performance microcomputers, ensures excellent focusing speed and accuracy. The Full-time Manual Focus override allows you to make fine adjustments while using AF, without having to switch from AF to MF mode.

Keep it steady with VC equal to 5 stops
Tamron’s best-in-class VC* image stabilization performance is equivalent to 5 stops**, according to CIPA standards. Plus, this lens offers a choice of three VC modes, including one exclusively for panning. Now you can match the VC mode to your shooting conditions and enjoy sharp, jitter-free handheld shooting―even in low light. * Among 70-200mm F/2.8 interchangeable lenses for full-frame DSLR cameras.

Two exclusive new teleconverters
Two exclusive teleconverters, which match the optics of the new SP 70-200mm G2, offer 1.4x and 2.0x magnification, and provide a maximum zoom range up to 400mm. These new teleconverters extend focal length of the master lens, making it possible to take pictures in farther telephoto ranges. Intuitive design and leading-edge performance In keeping with the SP series' “Human Touch” design, the A025 is both durably built and user friendly. The focus and zoom rings, textured grip and Arca-Swiss style tripod interface enhance speed and utility. And like all SP models, this new lens has an ergonomic shape for easy gripping and a lens hood with smooth curves that match the barrel.
