Tamron 150-600mm f/5-6.3 Di VC USD G2

This second generation “G2” lens builds upon the success of the SP 150-600mm F/5-6.3 Di VC USD. The new G2 version was developed to provide superior optical performance with today’s high resolution DSLRs and to add 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 tele converters. The new lens delivers outstanding performance and a luxurious, upscale appearance, including a metal lens barrel.

Press release:

Optical design refreshed to achieve even higher performance with three LD (Low Dispersion) lens elements completely eliminating axial and transverse chromatic aberrations. The design also features upgraded optical construction (21 elements in 13 groups) and leverages improvements in manufacturing technology. As a result, the lens delivers high resolution, improved sharpness and overall better performance.

 The lens coating is Tamron’s sophisticated eBAND Coating for eliminating ghosting and flare. It’s 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.

 The minimum focusing distance has been reduced to 2.2m (86.6 in), compared to 2.7m for Model A01, and has allowed for the wonders of tele-macro photography. Along with the AF speed being much more responsive with moving subjects. The Model A022 is equipped with a USD (Ultrasonic Silent Drive) ring-type motor that delivers excellent responsiveness and control. AF speed is significantly improved from current model, 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.

 The Zoom Lock mechanism quickly locks or unlocks the zoom at any position simply by sliding the zoom ring. Photographers can shoot from any angle without the zoom extending unintentionally. Additionally, the conventional Zoom Lock switch prevents unwanted barrel extension during transportation.

 The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellent. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints. For greater protection when shooting outdoors, leak-proof seals throughout the lens barrel help protect your equipment.

 It boasts an electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses*2. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.

The new textured grip and Arca-Swiss style tripod interface enhances both speed and utility. And because the tripod mount is made of lightweight magnesium, it is much easier to carry.
