SMC PENTAX F AF 1.7X ADAPTER Question !

Does anyone know if this adapter can be used on a AF lens, I would assume you set AF to manual on the camera ?

Yes and no - you leave the camera body set for AF (otherwise it won't try to auto focus), and the AF adapter will AF the same regardless of whether the lens mounted on it is AF or MF... You have to focus the lens to near the correct focus point and the AF converter will lock AF... I was using it with an AF lens yesterday with good results.
