Ai AF NIKKOR 20mm f/2.8D [Old lens]
1993年12月の発売で2019年11月の時点でも新品が販売されている。オートフォーカスのモーターは内臓されていないので、AFカップリングがついているカメラでないとオートフォーカスが作動しない。レンズ構成はAi Nikkor 20mm F2.8Sと同じと思われる。フィルター径は同じ62mm。フードはHB-4で、Ai Nikkor 20mm F2.8S用のHK-14とは異なる。
This lens was released in December 1993, and a new one was sold as of November 2019. Since the autofocus motor is not built-in, autofocus will not work unless the camera has an AF coupling. The lens configuration seems to be the same as Ai Nikkor 20mm F2.8S. Both filter diameters are 62mm. The hood is HB-4, which is different from HK-14 for Ai Nikkor 20mm F2.8S.
