Tamron SP 70-200mm 2.8 Di VC G2 Nikon Mt
Tamron SP 70-200mm 2.8 Di VC G2 Nikon Mt
The Tamron SP 70-200mm F/2.8 Di VC USD G2 Lens for Nikon F, a telephoto zoom lens for full-frame and APS-C DSLR cameras. The SP 70-200mm F/2.8 Di VC USD G2 Lens was developed by substantially enhancing the features of its predecessor. These include a thorough review of the optical, mechanical and electronic designs to increase autofocus speed and precision, reinforce VC (Vibration Compensation) functions and to shorten the MOD. New features include eBAND Coating, Moisture-Proof and Dust-Resistant Construction, Fluorine Coating and compatibility with teleconverters. The lens design features a metal-based barrel for improved handling and ease-of-use. The result of this dramatic evolution is SP 70-200mm F/2.8 Di VC USD G2 Lens, a high-speed telephoto lens that widens the scope of expression for photography in a broad range of genres, such as portraits, landscapes, sports and photojournalism.
Outstanding resolution and contrast reproduction performance, beautiful bokeh and full compatibility with Tamron teleconverters - Based on the current model (A009), 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 new A025 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.
Improved VC system provides highest Vibration Compensation ability in its class3 (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 (using VC Mode 3).
Demonstratively improved autofocus speed and responsiveness - The SP 70-200mm F/2.8 Di VC USD G2 Lens 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 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 50.7 inches in the older Model A009 to 37.4 inches for Model A025, 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 new A025 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.
Moisture-Proof and Dust-Resistant Construction - Ideal for use in outdoor photography, the new 70-200mm telephoto zoom has moisture-resistant construction because special sealants that are dust-resistant and moisture-resistant are used at every joint and seam. The sealant material helps to prevent the intrusion of any dirt, dust or water droplets, compared to conventional Moisture-Resistant Construction.
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.
8. 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 Nikon-mount lenses4. 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 ConsoleTM, an optional accessory product - 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.
Based on the rigorous quality standards worthy of the SP series, this new lens is manufactured with a thorough attention to details - For the SP series products in particular, Tamron has established rigorous design and quality standards. These standards apply to the optical design, mechanical design and the cosmetic appearance, as well as to such wide-ranging areas as the product’s robustness and improvements in the various individual functions. Tamron thoroughly reviews all of the design and manufacturing processes in order to offer products to customers with even-higher levels of precision and quality.
