Turn a knob and press a release tab and it's off. It would take seconds to move it from one to the other and presumably you'd only have one of the 70-200 lenses in your bag at any one time. To each his own but if I get a 70-200 f/4, and I'm seriously considering it, I think I'll try getting by with one foot at $100 a pop.
At the Google published exchange rate 10,800 Yen is about 119 dollars. Much less than in the U. S. or in Europe. I hope my Chinese "look alike" will be suitable. We'll see when I get it. 15 to 20 days delivery time from China.
I received the DSLRKIT Full Metal Tripod Mount Ring for Nikon AF-S NIKKOR 70-200mm f/4G ED VR lens from China which I bought through Amazon. It looks nice, fits well and does its job nicely. Once screwed on the collar is firmly in place.
Both this collar and the original Nikon RT-1 lens collar do not offer the Arca Swiss option. I think adding a plate as I have done with other lenses is no big deal.
I am very happy with the $180 saving (the RT-1 when I purchased in January was over $210) which I promptly used to buy something else. B+H and Adorama have lowered their price for the Nikon lens collar (to $170) as I bet nobody was buying it for over $210.
I'm not trying to say "throw your money around randomly", but I'm not putting my $1400 new lens at the mercy of a product from an unknown company who has unknown standards for things like hinges. I trust Nikon, but their usability generally sucks. I trust RRS and their usability is generally great. I went with the RRS. I won't worry about it.
I'm a little shocked Nikon isn't putting feet on lenses like this and really shocked the new 80-400 apparently comes without one.
