Some thoughts from my side:
1. A solitaire lens, or the beginning of a new series?
I think that will be the start of a new series, replacing the other superteles by weight reduced super priced FL versions. (Maybe with dedicated Teleconverters for each lens – not too practical if you use two at the same time.
Maybe in the renommée match against Canon Nikon will remember its 300 f/2 and bring a newer lighter successor in FL design.
2. some analogies
a)Nikon told us DX is sufficient, until they finally changed mind and marketing and went the FX route.
b)Nikon first promised ultra sonic motors for AF-S lenses, after Canon came out with those and then said, no we have a better solution, which was found in the “coreless”electronic motor technology used in the AF-I Superteles. Several generations of AF-S lenses with “silent wave motors” we know better
c) Nikon promoted their ED Glass invention with having the same potential to suppress chromatic aberration but better thermal and mechanical abilities than fluorite lenses.
Now FL lenses are coming, where hopefully these issues have been kept under control somehow and we are told that Fluorite lenses have lower dispersion than ED and even Super-ED glass (the one used just once – will it remain the only application – lots of developing efforts for just one lens if it does not also find its place in other branches of the Nikon business – outside photography)
4 My main thought is what does E mean for compatibility?
Well F-mount has remained unchanged but now it appears as if Nikon is doing in three steps, what canon has done with one (gaining a fresh new bigger-diameter bajonet mount). The never announced /kept secret full switch to electronic communication between body and lens with the G-series was a massive switch – but kept mechanical diaphragm control.
The E now brings that to full electronic operation. Whereas the 800 is not the first (we have seen the PC-E series) the PC-Es have kept the manual diaphragm button of their predecessor, wheras the 800 appears to fully rely on that. It is just a matter of time, until any new Nikon F lens is an E-type.
If I did not overlook something the consequences would be:
Older digital bodies such as the D200 are not usable any more
NONE of the film bodies can be used with new lenses
G lenses could not be used on older Nikon cameras, but with adapters on the products on other manufacturers. With E that won’t be possible in the future similar to the usage for movie cameras
Newer low level cameras on the long run won’t support older lenses any more, may it be MF, AF-D or even G type
BTW: It is not guaranteed that “semi pro” or even “full-pro” bodies will continue to support screwdriver AF
Now that’s what I call backwards compatibility
Disclaimer: Immanent to considering and guessing is that I might be wrong
