[QUOTE="gbt, post: 181766, member: 14278"] The slider switch limits the distance the AF will hunt for focus, quite useful if you are shooting sports/wildlife and they are within 30ft and infinity for instance. The switch is for manual aperture or auto aperture, auto means locking it at f22 on teh lens then your camera controls it. Hope that helps. [/QUOTE]
