이 렌즈는 어떤 렌즈인가요:? 니콘 85.8 mf

동일 질문을 니콘 포럼에도 했는데 답변이 달리지 않아 필포에도 동일 질문을 해봅니다.
해바라기 85.8은 알고 있습니다. 이건 처음 보는 렌즈인데 어떤 렌즈인가요? 널리 알고 있는 니콘 mf ai-s 외관과도 조금 다르구요. 이베이에 있더라구요. 급 호기심이 ㄷㄷㄷ

해바라기 다음 버전의 렌즈인가요? 보통 특성, 평가와 가격은 해바라기와 비교시 어떤지 궁금합니다.
This Nikkor 85mm f/1.8 lens was a pre-85mm f/2.0 Nikkor lens version. It has a 6 elements in 4 groups optical design.
This version of the lens was Inroduced in March, 1975 (S/N 410001 onwards). A few changes were also being made to the design of this lens. The traditional old Nikkor physical scalloped focusing ring has been changed to a rubberized type grip and the aperture ring has a diamond ridged type of design which is closer to a modern Nikkor lens exterior appearance. The closest focusing distance has improved to around 3 ft from the 3.5 ft found on earlier series. NIC lens coating was also believed being used for its various lens elements. The lens' 28' 30' picture angle (the widest among telephoto lenses other than the 58mm lenses) makes for easier operation when following moving subjects, particularly at medium distances; here, again the f/1.8 aperture proves useful, as it allows for stop-action photographs under most common lighting conditions.
