Autofocus/Manual focus switch
The ability to switch quickly between autofocus (AF) and manual focus (MF) is a great asset in many types of shooting, especially sports and nature photography. This is easily accomplished with Tamron's ingenious AF/MF system. By simply sliding the focus ring back and forth between the two positions you can select either the AF or the MF focusing position. In manual focus mode Tamron lenses provide smooth, precise manual focusing by turning their wide, well-textured focusing rings.

Filter Effect Control
Some filters, such as graduated NDs (neutral density) or polarisers, require rotation to maximise their impact. When a lens has a long hood attached, access to the filter to adjust its angle can be difficult. A Filter Effect Control, either detachable or built into the lens, solves this problem.
