The Tamron SP 24-70mm G2 is a fast f/2.8 zoom Lens 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. Tamron’s exclusive eBAND Coating substantially curbs ghosting and flare that can occur in backlit photography. Additionally, it provides the added conveniences of a protective Fluorine Coating on the front element, Moisture-Resistant Construction and a locking lens hood.
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 models. 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.
This lens 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.
Dual MPU (Micro-Processing Unit) control system
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
It 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 in the class (CIPA level of 5 stops). Even in low light or with slow shutter speeds, you 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 repellent 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.
