•When using FA lens with the K-mount Pentax camera having no lens information contacts, be sure to set the lens aperture ring to any f-stop other then A. If set to the "A" position, the lens will automatically be set to the minimum aperture, causing improper exposure.
CAUTION :
•Be careful not to damage or dirty the lens information contacts and AF coupler on the mount surfaces of the camera and lens. Otherwise, failure or malfunction may result. If this occurs, wipe them gently with a clean, dry cloth.
•FAJ28-80mm f/3.5-5.6AL and FAJ75-300 mm f/4.5-5.8AL lenses have A (Auto) posi- tion only, no aperture ring to set a f-stop manually. The camera body controls aper- ture settings on "A" position. Camera bod- ies and accessories that not compatible with "A" cannot be used.
