When the lens is set to manual focus position and the focusing ring is fully rotated to the right or left to manually focus the lens, it will keep rotating as no stoppers are provided at the (infinity) or shortest distance positions.

When the focusing ring on the lens is set to the autofocus position, the focusing ring is locked.

When used on the KAF-mount camera, set the same focus mode on the camera and lens. When the camera is set to the autofo- cus mode (AF single) and the lens to man- ual focus mode, the shutter cannot be released unless the focus indication appears in the viewfinder.

Note : infinity () mark except the FA

85mm f/1.4 lens

The focusing ring of the telephoto lens stops slightly past the mark. This is because tem- perature change causes the focusing point to shift, making the lens focus on a point past the mark. Even when shooting at infinity, be sure the image is in focus utilizing the focus indicator before releasing the shutter.
