The Tamron SP AF 180 mm f/ 3.5 Di LD IF Macro is a high quality full-format telephoto macro lens. It is indispensable when a greater working distance is required for shooting too scary subjects with a high magnification ratio. With rather slow autofocus it is not equipped with AF range limiter.
The lens features a Filter Effect Control (FEC) ring for rotating a polarizing filter with attached hood at the necessary angle. The FEC ring rotates the filter and the hood.
There is an AF/MF one-touch switch. Switching from autofocus to manual focusing is done by moving the focus ring back to the camera, in so doing the focus ring discloses the blue ring indicating that AF is off. When switching, focusing may slightly shift.
