The use of special, high-quality glass materials ensures accurate color reproduction and superior sharpness, perfect for the demands of today's high-end camera sensors. The optical design (17 elements in 12 groups) incorporates 2 XR elements (Extra Refractive Index), 3 LD elements (Low Dispersion), 3 GM elements (Glass-Molded Aspherical), and one hybrid aspherical lens element.

The high-performance lenses minimize image errors such as chromatic aberrations (color fringing), to which fast zoom lenses are somewhat more susceptible, while also providing consistently high image quality across the entire image area. The VC image stabilizer (Vibration Compensation) of the SP 24-70mm G2 is controlled, like the autofocus, by the Dual-MPU unit (Dual Microprocessing Unit). Additionally, a new algorithm has been implemented to optimize the control and signal processing of the VC system. The VC system now compensates for up to 5 stops, making it even better suited for handheld shooting in low-light conditions.

The new SP 24-70mm G2 is equipped with a Dual-MPU unit. Two separate processor units enable the high-speed processing of digital signals from the VC image stabilizer and USD autofocus. This allows commands from the camera and AF motor to be interpreted and executed with high precision almost instantaneously. All lens elements are coated with a specially developed eBAND coating (Extended Bandwidth & Angular-Dependency) by Tamron for the SP 24-70mm G2. This technology combines a conventional multi-coating with a nano-coating that has an extremely low refractive index. The lens hood of the new SP 24-70mm G2 now features an innovative locking mechanism that prevents accidental detachment or slipping of the hood during use.
