Another interesting thing I just went and measured....the Canon 400DOII is 23.4cm at 400/4...but it is only 26cm when the 1.4TC is added making it a 560/5.6...ie almost a 600/5.6 like what Nikon might give us.
We know from the 400/500/600PF patents that the 600 will be 5cm longer than the 500 so about 29cm (assuming this rumour is correct).
And one final observation based of the patents...the 400PF would be 18cm...well the 300PF/1.4 is only 17.2cm and gives 420mm (both of those differences are likely meaningless)....I can't see any reason for Nikon to ever produce the 400/5.6PF...the AF is already excellent with my 300PF/1.4...as good as the bare lens as far as I can tell...AF would be the only thing the 400PF might improve but I just don't see it being a substantial improvement...even my 500FL isn't that much of an improvement over the 300PF/1.4TC....
