Pentax Lens - Manual (Page 5)

The Pentax FA lenses are primarily designed
to work with the Pentax autofocus SLR (K
AF2 -
or K AF2 -mount camera), making autofocus
shooting possible.
When Pentax FA Zoom lenses with power
zoom function are used on the Pentax K
AF2 -
mount camera, the camera features a Power
Zoom system.
• An FA zoom lens without the power zoom
contacts are shown in the illustration does
not have the power zoom function.
• Do not damage or dirty the power contacts.
