You all are touching on the same subject I continue mulling over in my head: I know I could get along with just the 600PF (and 1.4TC) from here on out, is the 800PF still worth keeping? Armchair QB'ing the question is easy when I'm stuck inside during the winter, but I 100% know that when Spring Migration rolls around and Warblers are plentiful, the 800 will be indispensable, and I'd regret selling it. Part of me wants to sell, yet my rational side disagrees and tells me to wait until after I've shot both during the best/busiest time of year coming up here in April/May. The 1-stop advantage of the 800PF vs. the 600PF + TC is huge once forest canopies return and there's a lot of shadows.
Last May, I did a 4-day solo camping trip and did nothing but shoot birds (mostly Warblers) from sunrise to sunset. It was heaven. Birding uninterrupted for days on end really let me dig into my gear and see how it performed from constant use, side-by-side, in a myriad of conditions. At the time I had the Z9, 800PF and 400 4.5, and the three main take-aways from that trip were that I always too short with the 400, the MFD and tight FOV of the 800PF was an hindrance in the leafy forest environment, and constantly switching lenses is a huge distraction/disadvantage/liability. I also came back with some major tennis elbow that still aches to this day.
I've booked the same trip again this year, and this time around it'll be a shootout to see if the 600PF can strike the Goldilocks role b/w the 400 and 800. However, that trip had me crying out for a versatile zoom in order to cut down on the lens swaps, so my 180-600 may absolutely steal the show from any primes I choose to take. That, or getting a second camera body may be beneficial, so I'm presently debating another Z8.
