Not to be confused with "series-E" Nikon lenses of the past, Nikon's formal announcement of the new 800/5.6 AF Nikkor lens heralds the acceptance of the E-type brand of Nikkors, previously used only in the 3 PC-E lenses.

A few of us saw this coming. (In fact, I predicted this move in a 2009 thread 3.5 years ago after the PC-E lenses came out.):

It was only a matter of time before Nikon decided to move to electronic diaphragm coupling in its highest end professional lenses. The 800/5.6 marks the move of this feature into non-PC lenses. I would expect more new professional Nikkor lenses to be designated "E" in the coming years, instead of "G", as it improves the power aperture feature when shooting video, and also live view.

During the AF era, we've gone from AF to D to G, with AF-S or VR in some lenses, and now we have the new type E. The E-type interface might mean incompatibility with certain older camera bodies (depending on whether the lens includes a manual stopdown control or not).

It is not clear if the F6 is compatible with this aperture stopdown method. If not, this marks the break in compatability of film cameras with the newest lenses. That said, I wouldn't hold my breath; it's unlikely that many lenses will be "E" type in the near future; most likely only the highest end professional lenses for a while.
