Lens Technology: Dynamic Rolling-cam Mechanism

Dynamic Rolling-cam mechanism operates the heavy focusing unit of the fast-aperture with high speed and accuracy
Thanks to Dynamic Rolling-cam mechanism, which operates the heavy focusing unit with high speed and accuracy, TAMRON has succeeded in minimizing the drive load placed on the focus lens component. This breakthrough ensures stable AF operating performance and improves reliability even under the harsh shooting conditions of professional use, including high and low temperature extremes.
