Re: 600PF??

Read nothing besides what was posted early last year on NR wrt to the Nikon patents: for 400, 500 and 600.

https://nikonrumors.com/2018/02/01/the-latest-nikon-patents-400mm-500mm-and-600mm-f-5-6-phase-fresnel-pf-lenses.aspx/

The 500 PF is all and more that's being written about it in the reviews. I still argue, however, that a 400 f4E PF of about 220mm by 110mm will be far more versatile in haptics and TCF (Teleconverter Factor: ie T3C0.5 versus TC1C -0.75 for a 5.6 telephoto] as it will work with all 3 Nikon TCs out a 800 f8, and a useful reach of 560 f5.6 with TC14. These stats apply to the triumvirate of Nikon DSLRs best suited to wildlife and action genres. Note my testing the Z7 with the 500 PF + TC2 does gives AF at f11 - but this rig struggles.

The 400 f4 PF should weigh less than a 600 f5.6, and be easier to handhold with similar proportions to a 200 f2G but it should weigh 2kg at most (guesstimate!)
