Thank you for confirming the tripod collar difference, it's seems lost on the internet,,, Can you remember the details? I recall we talked about it on the old NikonGear many years ago,,, I'll se if I can locate the drawings,,,
I'll report back with my finding on that as well, I have ordered two different versions of alternative Arca/RRS compatible lens foot for it.
I have also upgraded to HK-30 lens hood - The Supplied HK-31 is designed to accommodate the lens foot when reversed for transport, just plainly wrong/hilarious,,,
For sure I would have liked the Mark II version but not at double/ the cost, I can dial up contrast in PP if and when I like enough for my taste.
Some online reviews mention the first one as the sharpest, I have a hard time understanding how this could be, I have shot many lenses before and after the Nano coating versions,,, never seen that difference that the first would be sharper,,, Anyway this lens is up there in sharpness where only a handful of the best Nikkor lenses are performing so I'm very happy with the original.
