Tamron, a leading manufacturer of optics for diverse applications, 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. Model A032 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). The use of specialised, high quality glass materials (offering greater optical transmittance) for the lens element assures superior colour reproduction and greater sharpness, while the application of Tamron’s exclusive nanotechnology-based eBAND Coating substantially curbs the ghosting and flare that are prone to occur in backlit photography, successfully improving the overall optical performance of the lens.

Additionally, model A032 provides the added conveniences of protective Fluorine Coating, 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 and many others.

Sophisticated Design Delivers Superb Performance & Ultra-High Image Quality

The use of specialised, high-quality glass materials assures accurate colour 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 minimise axial chromatic aberrations, transverse chromatic aberrations, spherical aberrations and distortion, and allow a compact design that achieves superior image quality.

 eBAND Coating with Superior Anti-Reflection Properties & Reduces Ghosting & Flare

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 optimal application of this eBAND Coating in combination with Tamron’s BBAR (Broad-Band Anti-Reflection) Coating successfully and substantially curbs the ghosting and flare that can occur when photographing backlit subjects.

New Dual MPU Control System*3 Provides Faster & More Precise AF & Improved VC

The innovative control system uses a Dual MPU (Micro-Processing Unit) 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.

High-performance MPU for AF dramatically improves autofocusing accuracy & speed

The A032 is equipped with its own MPU (microprocessor unit), with embedded DSP (Digital Signal Processor) blocks that enable high-speed digital signal processing, achieving both excellent responsiveness to signals from the camera and high-precision AF performance.

Dedicated MPU delivers the highest vibration compensation ability in class*2 (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 & 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 lens hood is equipped with a locking mechanism, which prevents detachment due to unintentional contact during use.

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 customise 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*4. More precise diaphragm and aperture control are possible because the diaphragm blades are driven and controlled by a built-in motor through electronic pulse signals.

*4 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)

Manufacturing According To Rigorous Quality Standards Worthy of the SP Series

Tamron has enhanced the SP series lenses to fulfil high-level photographic requirements and provide the pleasure of ownership. While introducing a new exterior design, Tamron reviewed the SP series standards. The new SP series has been developed by setting rigorous standards for design, manufacturing and quality that apply to the optical design and mechanical design as well as such wide-ranging areas as the product’s robustness and improvements in a variety of individual functions. For this model, Tamron has introduced a unique MTF (Modulation Transfer Function) tester, which was developed exclusively for Model A032, and reviewed the management method. This has helped to achieve a more consistently superb optical performance, making it a lens that fulfils the demand for higher image quality that is compatible with the latest high-pixel cameras. To maximise the optical performance of the SP series, Tamron will continue to enhance the accuracy of the component parts of each lens element unit and improve the mechanical precision of the entire lens, thereby achieving a high overall performance.
