The AF drive continues to employ the VXD4 linear motor focus mechanism, combining class-leading speed and precision, and enabling fast and accurate focusing. The precise calculations, reworked to update the 50-400mm F4.5-6.3 (Model A067) and 150-500mm F5-6.7 (Model A057), have been applied to enhance tracking moving subjects, ensuring you never miss decisive scenes whether shooting still images or video. Moreover, the 70-180mm F2.8 G2 is equipped with TAMRON’s VC5 mechanism. This suppresses camera shake that tends to occur when shooting at the telephoto end, during close focusing, or when shooting in low-light conditions, enabling sharper results.

Shooting at close distances that were possible only during manual focusing with the 1st-generation model is now possible when using autofocus with the 70-180mm F2.8 G2. Tamron has succeeded in shortening the MOD to 0.3m (11.8in) at 70mm. At 70mm, the working distance is 12cm (4.7in) and the maximum magnification ratio is 1:2.6. This expands the possibilities for expression with a single lens.

The 70-180mm F2.8 G2 is compatible with the Tamron Lens Utility software developed in-house by Tamron. Tamron Lens Utility lets users change lens settings, assign camera body functions, and update firmware when necessary. Users may customize functions for various still photography and videography shooting styles, for a more personalized and fulfilling shooting experience.
