tamron 150 600Tamron has updated its “big gun” with the release of the SP 150-600mm f/5-6.3 Di VC USD G2. This second generation “G2” lens adds improvements to several features including speed and accuracy of AF and VC (Vibration Compensation). Also, several new features have been added: Flex Zoom Lock mechanism, Fluorine Coating and optional teleconverters. The new lens features a metal lens barrel.

The Canon and Nikon mount models will be launched simultaneously, with the Sony version to come later.

Three LD (Low Dispersion) lens elements completely eliminate axial and transverse chromatic aberrations, says the company. The design also features upgraded optical construction (21 elements in 13 groups) and leverages improvements in manufacturing technology. As a result, says Tamron, the lens delivers high resolution, improved sharpness and overall better performance.

Tamron’s eBAND Coating is said to eliminate ghosting and flare. eBAND (Extended Bandwidth & Angular-Dependency) Coating is a nano-structured layer deployed on the lens element surface. In addition to regular anti-reflection coatings, eBAND Coating offers higher light transmission and significant improvement in anti-reflection characteristics, especially against angulated incident rays. Combined with of BBAR (Broad-Band Anti-Reflection) coatings, flare and ghosting are reduced to imperceptible levels, notes the company.

Minimum Object Distance is now 2.2 m (86.6 in), compared to 2.7 m for the previous model. AF speed is faster and much more responsive with moving subjects. The lens is equipped with a USD (Ultrasonic Silent Drive) ring-type motor that delivers excellent responsiveness and control. AF speed is significantly improved, and it enables accurate high-speed focus even when capturing moving subjects.

When shooting with AF, the Full-time Manual Focus override allows you to instantly make fine focusing adjustments manually, without having to switch between modes.

VC performance is now 4.5 stops and offers three modes optimized for different situations.
