It has been my opinion for a while that the new Nikkor Z 70-200mm f/2.8 zoom is a most remarkable lens, sure to make its place as one of the all-time great Nikon lenses.
This lens takes the TC-1.4 without blinking and the same goes for a small extension tube (11mm), or both at once. I am sure there is some degradation, but so far I can’t see any effect I would worry over.
I am most interested to note that this lens has a “style” to it that I like, as opposed to what I call clinical-like no-style lenses. Yes, its big, heavy-ish, and it likes a tripod, but I know people who are using it hand-held for nature photos and getting great results.
Given the availability of extension and TCs, I can get as close as I want and it also doubles for a decent telephoto lens. I guess my main point other than satisfaction is that here is the Swiss-Army Knife in my lens collection. I can do most everything and well, close-up, portrait, and distance with a certain grace. I really like it.
