Hello all! I saw a really attractive lens in my local photo shop the other day, a Nikkor 300/4.5 AI MF. It seemed very robust (quite heavy too), tripod mount, very good condition (almost like new). The salesman told me itīs quite old, maybe even 15 years, so my question is: is it any good? Iīm trying to find a good tele lens to replace my Sigma zoom, and this Nikkor could well fit into my budget. I donīt need the really wide apertures, since I most often use a tripod with longer lenses. I understand thereīs a IF ED version of this lens too, but that costs way too much. Anyone having first-hand experience of this lens? Then please respond!! Bye! Magnus
