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 uniform high image quality across the entire image area.

The VC image stabilizer (Vibration Compensation) of the SP 24-70mm G2 is controlled by the Dual-MPU unit (Dual Microprocessing Unit), just like the autofocus. Additionally, a new algorithm has been implemented to further optimize the control and signal processing of the VC system. The VC system now offers up to 5 stops of stabilization, 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 (Dual Microprocessing Unit). Two separate processor units allow for the high-speed processing of digital signals from the VC image stabilizer and USD autofocus. For example, commands from the camera and AF motor can be interpreted and executed with lightning speed and high precision.

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 falling off or slipping of the hood during use.
