I have that lens, the OD of the rear element is 64mm.
The OD of the front element is 70mm.
I have press fit covers for both, with the front being a plastic Nikon unit and the rear being a quite old Wollensak Rochester metal unit with some soft velour type material inside.
I use my film darkslide for lens shading for everything from 65mm through to 250mm with nary an issue. A compendium lens shade has been on my wish list for around the last 20 years, somehow I think one of them has missed my boat.
There have been very few times I've wished for a lens hood, last week while photographing a tree trunk surrounded by raging floodwaters, was one of those times one could have been handy. The reflection of the foam from the water was certainly a slight issue that occurs quite rarely; this was one of those times.
Here I'm using my Fujinon 90mm f/8 lens.
