The high-speed zoom lens is designed for full-frame DSLRs

The latest zoom lens from Tamron offers a fast maximum aperture of f/2.8 and rapid autofocusing. Other features include high vibration compensation, eBAND coating to reduce ghosting and flare, as well as improved autofocusing accuracy. Pricing is yet to be confirmed, but availability is expected from July. For more information read Tamron's official press release below:

Tamron introduces next-generation high-speed 24-70mm F/2.8 zoom lens with advanced features

Versatile new lens delivers ultra-high image quality, image stabilization of 5 stops*1) and superb performance even in backlit scenes

SP 24-70mm F/2.8 Di VC USD G2

Tamron announces the launch of a new high-speed zoom lens, SP 24-70mm F/2.8 Di VC USD G2 (Model A032), for full-frame DSLR cameras. This new lens is a fast F/2.8 zoom that achieves top-level image quality. The new Dual MPU (Micro Processing Units) provide rapid autofocusing with improved accuracy and the highest vibration compensation performance of any lens in its class*2) (CIPA level of 5 stops*1)). Tamron’s exclusive eBAND Coating substantially curbs ghosting and flare that can occur in backlit photography. Additionally, model A032 provides the added conveniences of a protective Fluorine Coating on the front element, Moisture-Resistant Construction and a locking lens hood. Photographers can use this new high-speed zoom lens for wide-ranging purposes, including landscape, portrait, news, travel as well as many others.

Sophisticated design delivers superb performance and ultra-high image quality

The use of specialized, high quality glass materials assures accurate color reproduction and superior sharpness, perfect for today’s high-pixel-density cameras. Optical construction (17 elements in 12 groups) uses 2 XR (Extra Refractive Index) elements, 3 LD (Low Dispersion) elements, 3 GM (Glass-Molded aspherical) and one hybrid aspherical lens element. Together they minimize axial chromatic aberrations, transverse chromatic aberrations, spherical aberrations and distortion, and allow a compact design that achieves superior image quality.

eBAND Coating provides superior anti-reflection properties, and reduces flare and ghosting

The new A032 features Tamron’s original eBAND (Extended Bandwidth & Angular-Dependency) Coating, a technology combining a nano-structured layer that has an extremely low refractive index with conventional multiple-layer coatings to provide superior anti-reflection performance. The eBAND Coating substantially curbs the ghosting and flare that can occur when photographing backlit subjects.

New dual MPU (Micro-Processing Unit) control system*3 provides faster and more precise autofocus and improved Vibration Compensation

The innovative control system uses a dual MPU design with enhanced computing capacity. The MPUs have powerful, built-in DSP (Digital Signal Processor) blocks that achieve quicker and more precise AF performance, and more consistently powerful Vibration Compensation. The features combine to provide outstanding performance at night and in low light.

Dedicated VC processor delivers highest VC ability in class (CIPA level of 5 stops*1).

The new A032 is equipped with Tamron’s proprietary VC (Vibration Compensation) system. Adding an MPU dedicated to VC processing unleashes a new-generation algorithm, ensuring the highest vibration compensation ability*2) in the class (CIPA level of 5 stops*1). Even in low light or with slow shutter speeds, photographers can enjoy shake-free handheld shooting with ease and comfort.

Fluorine Coating and Moisture-Resistant Construction

The Fluorine coating applied on the front element surface is water and oil repellant and allows safe and easy removal of fingerprints, dirt and smudges. The coating also provides an enhanced level of durability, and will sustain its effectiveness for years. In addition, seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or rain drops to provide moisture-resistant construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.

Lens hood equipped with new, convenient locking mechanism

The flower-shaped lens hood locks into place to prevent misalignment which might possibly cause vignetting.

Compatible with TAMRON TAP-in ConsoleTM, an optional accessory

The new A032 is compatible with the optional TAMRON TAP-in ConsoleTM, an optional accessory product that provides a USB connection to a personal computer, enabling users to easily update a lens’s firmware as well as customize features including fine adjustments to the AF and VC.

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 employed in Nikon-mount lenses*3). More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a built-in motor through electronic pulse signals.

*3 Available only with cameras compatible with the electromagnetic diaphragm (D5,D4s,D4,D3X,Df,D810,D810A,D800,D800E,D750,D600,D610,D300S,D500,D7200,D7100,D7000,D5600, D5500,D5300,D5200,D5100,D5000,D3400,D3300,D3200,D3100).  (As of May, 2017; Tamron)

Based on the rigorous quality standards worthy of the SP series

For the SP series products in particular, Tamron has established stringent design and quality standards. These standards apply to the optical design, mechanical design and the exterior design, as well as to such wide-ranging areas as the product’s robustness and improvements in various individual functions. Tamron thoroughly reviews of all its design and manufacturing processes to offer products with ever-higher precision and quality levels.

For Model A032, reviewing the management method for the MTF (Modulation Transfer Function) tester has helped achieve more consistently superb optical performance. The mechanical parts were improved and a new exterior design has been adopted. To ensure maximum optical performance, Tamron has enhanced the accuracy of component parts comprising each lens element unit and increased the precision of the overall zooming mechanism.
