the style of the markings shows quite clearly its a Nikon
You look at the apeture ring, it is totally 101% Nikon style. the font and font size of the markings, the orange coloured number f/22, the "dotted" grip of the apeture ring --> 101% Nikon Style
as for the barrel of the lens, it is the same material as the old push-pull Nikon 80-200 f2.8 lens
could it be that the old user replaced the top rubber with 3rd party rubber? causing it to look bigger? like modern day gaffering?
Bought this from a fellow snapper. Is this a NIKON?
No NIKON logo or model on lens.
