I just received my AF-S 300 f/4 yesterday that I bought used. I have not had a chance to do anything but mount it to my D300 so far. I can't wait to get out with it this weekend.
I have a question though since this is my first heavy and long lens, let alone a prime. There is some play went mounted to my D300. More twisting play and very little side to side. Is this normal? I see no brassing on the lens at all, in fact the entire lens is practically brand new. Should I be concerned or or at ease knowing I got a steal of a deal.
Thanks,
Dave
