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 tele converters 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. 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. 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. 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. Two exclusive tele converters, 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 tele converters extend focal length of the master lens, making it possible to take pictures in farther telephoto ranges.

Optical Construction

The Tamron 70-200mm f/2.8 lens comes with an optical design of 23 elements in 17 groups, including an extra Low Dispersion and a Low Dispersion element that control chromatic and spherical aberrations. The eBAND Coating reduces ghosting and flare in the image, thus improving the contrast and saturation.

USD motor and VC Image Stabilization

The Tamron zoom lens is equipped with an Ultrasonic Silent Drive AF motor that ensures a noise-free focusing performance. Moreover, the focusing system allows you to take photos of objects from a minimum distance of 50.7inch. This telephoto lens is ideal for both sports and wildlife photography, thanks to the Vibration Compensation Image Stabilization. It reduces the visual appearance of camera shakes by 5 stops, helping you to take photos in low light.

Consistent Aperture and Circular Bokeh

The aperture of this Tamron lens remains constant at f/2.8 to maintain the image look. Also, the wide aperture supports low-light shooting and enhances the shallow depth of field. With the 9-blade diaphragm, you get a circular bokeh in the out-of-focus background.

Weatherproof Construction and Tripod Support

The internal AF motor and other electric parts are shielded by the moisture-resistant body that enables you to use this Tamron telephoto zoom lens in inclement weather. Along with the lens, you get a tripod collar that prevents excess load on the camera mount when the lens is attached.
