The AR-mount lenses may be divided into several types, based mostly on cosmetics. When the Autoreflex T was introduced in 1967, Konica added a lever to signal the widest aperture setting for the through-the-lens (TTL) in-body light meter; Konica also offered a free service to retrofit the earliest AR-mount lenses with the new lever.
