Outstanding resolution and contrast reproduction performance, beautiful bokeh and full compatibilitywith Tamron tele converters.
The optical design has been revised and improved. Both the resolution and contrast reproduction performance far exceed the present levels.
Bokeh has been enhanced and expanded to deliver outstanding background effects across the entire zoom range. Use of a circular diaphragm with nine blades further improves bokeh. The optical design of the Tamron SP 70-200mm f2.8 Di VC USD G2 consists of 23 elements in 17 groups. Optimum deployment of XLD (eXtra Low Dispersion) and LD (Low Dispersion) glass elements thoroughly eliminate chromatic aberrations, which tend to become particularly prominent in high-speed telephoto lenses, across the entire zoom range, while ensuring uniform, high-level image quality even on the periphery of the image plane.
The lens is also fully compatible with the TELE CONVERTER 1.4x (Model TC-X14) and TELE CONVERTER 2.0x (Model TC-X20), which increase the focal length of the lens to 1.4 times and 2 times the original, respectively. Both tele converters are carefully designed and constructed to provide outstanding high quality.
Improved VC system provides highest Vibration Compensation ability in its class (5 stops using CIPA standard compliant) and offers three situation-specific VC modes.
Utilizing Tamron’s original VC (Vibration Compensation) system, which uses a moving coil mechanism, further reinforcement of the drive system power and control performance has now achieved the highest VC level in its class, with an image stabilization performance of 5 stops according to the CIPA standard (whenusing VC Mode 3).
Also, the VC system of the Tamron SP 70-200mm f2.8 Di VC USD G2 offers three VC modes, including one mode exclusively for panning. Photographers can freely choose between the different VC modes according to the shooting conditions. Even for telephoto shooting in low light, which tends to be severely affected by camera shaking, photographers can now enjoy jitter-free handheld shooting with much greater flexibility.
Demonstratively improved autofocus speed and responsiveness.
The Tamron SP 70-200mm f2.8 Di VC USD G2 is equipped with a USD (Ultrasonic Silent Drive) ring-type ultrasonic motor, whose outstanding responsiveness and control ensures accurate high-speed focusing. Incorporating two advanced, high performance microcomputers and optimizing the algorithm has improved both the focusing speed and accuracy compared with the SP 70-200mm (Model A009). Additionally, thanks to the Full-time Manual Focus override mechanism, photographers shooting with AF can instantaneously make fine focusing adjustments using MF without wasting time by switching the AF-MF mode back and forth.
Focuses closer (shorter Minimum Object Distance, or MOD) for greater versatility.
Improvements made to the focus cam and zoom cam inside the lens barrel have reduced the MOD from 1.3m (50.7 in) in the older Model A009 to 0.95m (37.4 in) for G2, which has a maximum magnification ratio of 1:6.1. The shorter MOD, coupled with the excellent optical performance of the SP 70-200mm (Model A025), allows photographers to further broaden their range of expression.
Optimized and exclusively designed eBAND Coating.
The Tamron SP 70-200mm f2.8 Di VC USD G2 features Tamron’s original eBAND (Extended Bandwidth & Angular-Dependency) Coating, a technology that combines a nano-structured layer with an extremely low refractive index with the conventional multiple-layer coatings. Optimized and exclusively designed for this new zoom, the eBAND Coating provides superior anti-reflection performance, effectively reducing any flare and ghosting. Even when taking backlit portraits, the new lens delivers flawless, crystal clear images.
Fluorine Coating for greater protection.
The front surface of the lens element is coated with a protective fluorine compound that is water-and oil repellant. The lens surface is easier to wipe clean and less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.
Electromagnetic diaphragm system now used also for Nikon-mount lenses.
An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now available for in Nikon-mount lenses. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by the motor through electronic pulse signals.
Lightweight and easy-to-hold tripod mount is compatible with Arca-Swiss style quick release plates.
A new textured grip and Arca-Swiss style tripod interface enhances both speed and utility. Because the tripod mount is made of lightweight magnesium, it is much easier to carry.
Compatible with TAMRON TAP-in Console.
The optional TAP-in Console provides a USB connection to a personal computer, enabling users to easily update the lens firmware as well as customize features, including fine adjustments to the AF and VC.
