ok - i am doing this for a friend of my son who has some gear to sell. if it is inappropraite then mods please delete. my son's friend has a bunch of nikon lenses which he does not know the value of. he wants to sell them and asked me for an estimate of their worth. i really have no idea so i thought i'd ask some of you folks. here is the list - Nikon Lenses 24mm f/2.8 (3.5?) AIS 35mm f/2.8 AI-ed (F-series with AI ring) 50mm f/1.2 AIS 75-150mm zoom f/3.5 AI E series metal 200mm f/4 Q series no coordination with camera unless you have an FE/FA/FM 2x teleconverter Vivitar 70-200mm zoom f/4-5.6 AI now - these lenses are in brisbane, australia, but i imagine they are worth about the same anywhere. does anyone have any estimates as to their worth?
