Tamron 24-70 G2 - SP 24-70mm F2.8 Di VC USD G2Tamron’s best-in-class, high-speed standard zoom lens
The Tamron 24-70 G2, Model A032 high-speed zoom is designed to maximize the potential of the latest high-pixel-density cameras while delivering best-in-class image quality with the use of specialized, high quality glass materials that offer greater optical transmittance. The A032 offers the highest image stabilization in its class with 5-stop performance.
As a premier camera lens manufacturer, the combination of advanced technology, versatility and superb image quality makes the easy-to-use A032 zoom an excellent choice for everything from landscapes and portraits. Find an authorized Tamron dealer to get yours today!
The use of new specialized, high quality glass materials that offer greater optical transmittance are used in the new model A032 to ensure superior color reproduction and even greater sharpness. The A032 lens comprises 17 glass elements in 12 groups, including: 2 XR (Extra Refractive Index) glass elements to counteract optical aberrations; 3 LD (Low Dispersion) elements to minimize axial chromatic aberrations that can occur with telephoto, as well as transverse chromatic aberrations that can be an issue with wide-angle; 3 GM (glass-molded aspherical) elements; and 1 hybrid aspherical lens element that effectively neutralizes spherical aberrations and distortions to create superior image quality. Thanks to a combination of these special glass materials, the A032 achieves previously unseen levels of accurate color reproduction and depictive performance.
The new A032 features Tamron’s original eBAND (Extended Bandwidth & Angular-Dependency) Coating, a technology that combines an extremely-low-refractive-index nano-structured layer with conventional multiple-layer coating techniques 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.
The A032 zoom features a new control system that uses a dual MPU (micro-processing unit) process. In addition to an MPU with built-in DSP (Digital Signal Processor) blocks for superior signal processing, Tamron has added an MPU dedicated solely to vibration compensation . The result is quicker, more precise AF performance and more consistently powerful VC (Vibration Compensation).
*3 A new control system using two high-performance MPUs (micro-processor units)
The A032 is equipped with its own MPU (micro-processor unit), with embedded DSP (digital signal processing) blocks that enable high-speed digital signal processing, achieving both excellent responsiveness to signals from the camera and high-precision AF performance.
The highest vibration compensation (VC) levels in its class
The new A032 zoom lens is equipped with Tamron’s original VC (Vibration Compensation) system. With the addition of an MPU specially dedicated to VC processing, the A032 offers the highest vibration compensation available,*1 with CIPA image stabilization performance level of 5 stops.*2 Now you can enjoy jitter-free handheld shooting and more flexibility—even in low light conditions.

*2. CIPA Standard Compliant. For Canon:EOS-5DMKIII is used. For Nikon:D810 is used.
Our attention to every engineering detail has yielded the most advanced optical and electro-mechanical design featured in the newest Tamron SP lenses, culminating in a new benchmark for high performance and visual elegance.
The design philosophy is based on human touch and is an integral factor in macro photography. The newly designed all-metallic barrel features an embedded concave ring at the base of the lens – for a firm hold and comfort necessary for a steady shot.
Switches are larger and reconfigured for smoother torque and the typeface has been redesigned for intuitive legibility.

Optical Construction (17 elements in 12 groups)
MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.
The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.
Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.
Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance.
