I've kept my 600mm f/4 AFS G for exactly that reason. I get $2500 worth of use out of the lens - and it's a great lens - but I also have the 800mm PF when I need something lighter and more portable. I have the 400mm f/4.5, F mount 600mm f/4, and 8000mm PF which covers the range of options quite well. But if I had an interest in a 600mm f/4, it's quite good. You could get the 600mm PF and the 600mm f/4 G for just over half the price of a Z 600mm f/4 TC - providing a lighter and heavier option.Yeah, your not wrong. I guess for me "worth it" is quality of lens vs price point."worth it" is consistently one of my most hated phrases.
It really depends on too many individual things to say yes/no to. What you shoot, how often, how much you're willing to carry, budget, etc etc etc.
There's a lot of good f mount stuff, especially on the used market now, but most of the z lenses are just better in most ways by a large margin
The Z 600/4 TC VR S is $14k vs the F 600/4 used is less than $2k.
Now I imagine the Z is better across the board, but is it $10k better?
The 60mm f/2.8 AF-S Micro is another good option - especially for a short macro lens - and as good or better than the Z 50mm MC. The 105mm micro lenses for F-mount are all very good - but the Z 105mm MC is better. So needing a short macro for slide/negative duplication or general use, you could get the 60mm lens.
There are also lenses like the 19mm PC that are not available in Z-mount and are optically fantastic. Again - the price of used copies of that lens has dropped a lot. It's manual focus only and a specialty lens, and works well on the Z cameras.
