Just my opinion because of how I use my equipment but I "sort of" wish I had my 200-500 back or spent the money for the Z 100-400 and Z TC-2.0 on a 500 PF and TC-1.4 III. One of my biggest complaints is the Fly By Wire manual focus. I shoot wildlife, landscape, and astrophotography. It is extremely hard to manual focus on stars and get it right and if I have to replace the battery during the night my focus resets to infinity which is not always where it needs to be so then I have to try and readjust. I will say though when I get keepers in all forms of my photography this lens like most of the S series lens kicks butt. I do find myself using higher ISO's and Shutter speeds for day time photos than what I do with my F lens. My hits and misses for day time photos are about the same as the 200-500 and with the 200-500 you have that extra 100mm, but that said my full on shots with the Z TC-2.0 (800mm @ F/11) have all been beyond my expectations. So I'm still torn between keeping or selling. The other day Nikon had refurbished 500 PF for $2499 I had one in the cart but didn't pull the trigger and when I went back a few hours later they were all gone. Maybe that's a sign haha. If I can get some clear nights I will be out and try to come up with some kind of resolve on star focus, I have some ideas that might help, if not I'll just FTZ my F mount 300 and see where I'm at later. HaHa, one idea I have thought about is buying a 12"
Schmidt-Cassegrain scope, but then I get that look from my wife LOL.
Here's my old 200-500 on my EQ mount.
