func_desc['dx_contacts']='DX contacts provide the camera with information about the type of film used and its sensitivity. Never touch the DX contacts; if dirty, they may report the wrong film speed.';
func_desc['mounting_index']='The mounting index (a red dot) provides visual guidance for inserting the lens into the mount.';
func_desc['bayonet_mount']='The bayonet type lens mount (Minolta "A" type) allows the lens to be mounted on the camera. It is not compatible with older manual focus Minolta lenses of type "SR", "MC" or "MD".';
