Hello all. I found a Nikkor AF 50mm 1.4 (non D) lens for what I think is a good price but can't find any pricing info on it. I have the SN and with that I know it was made between 86 and 91. But other then that I have found nothing. So here I am asking all of you (which I hope to talk with often as I learn and share more in time). So I feel that $75 is a good deal for a lens I should have in my bag. Any thoughts on this? I have a F5 (and a d5200 which the lens will not be used on) and if nothing else my niece just got a F3 from her great-grand father and might just get it for her. Thanks in advance.
