when can I order it?

As it has a smaller front element and is slightly smaller overall than the 800 PF. The 800 f6.3 PF is US$6,500 so, I would suggest the 600 f5.6 PF to be about US$5,500-US$6,000.How much do you think Nikon will ask for this?
What is so expensive to implement an internal TC?Like to see a 600 PF (or 400 F/4.5 equivalent at 600mm FL) at F/5.6.
Wonder if Nikon will ever make PF/TC combinations? Would increase weight, size and cost.
Any internal TC is not really a TC.What is so expensive to implement an internal TC?

600mm divided by f5.6 requires a minimum front element diameter of 107.14mm.The article itself says the majority of patents never make the light of day.
A patent like this will not keep others from bringing a product that is functionally the same to the market. What it does is protect their design from being copied and brought to the market.Some patents are never intended for production . Their existence is to block others from bring a product to market. I have no insight into Nikon's plans for their patents.
Yes, I saw it... in a vitrious sort of way...understood your joke. was humorous
not sure what I would decide if given the choice of a 600 F/4 TC or 600 F/5.6 PF w/o a TC. Now if they had a 600 F/5.6 PF TC it would be an easy choiceIn a perfect world a 600 mm f5 .6 PF would cost around 85% of the price of the 800 f6.3 PF.
