The FA* 600mm/4 can still be had by special order even though it has officially been canceled. However, it will be ~ $8500 usd if not more.
The MSRP on the Nikkor 600mm f4 G ED VR is $10,300 and the Nikkor 500/4 is $8580. I doubt the MSRP can be beat by much on these be glasses. They also have the Nikkor 400/2.8 is $9550.
Nikon also has 3 different 300mm lenses listed:
AF-S Nikkor 300mm/4 D IF ED ($1500 msrp)
AF-S Nikkor 300mm/2.8 G ED VR II ($5900 msrp)
AF-S Nikkor 300mm/2.8 G IF VR II ($5500 msrp)
There are some Sigma super tele alternatives as well. The big thing for me is the cost of these glasses whether it is Nikon or Pentax. As a biologist, I could put these things into service, but the capital outlay isn't there for me and not entirely Pentax.
