Forced indoors by steady rain the entire afternoon, I had a chance to poke through some archived photos in an effort to reassure myself that my current gear choices are ones I can stick with for some time to come.
Nikon’s 500mm f/5.6 PF could be considered an alternative to the RF 100-500mm, if only they made either a DSLR or mirrorless that can AF consistently with critical accuracy. Sony’s under-designed glass and reliance on software “corrections” puts them out of the picture, no pun intended.
Looking at some shots from a few years ago taken with the Canon 80D and 100-400mm II (two posted below) reassured me that I’m on the right track brand-wise. If the RF 100-500mm turns out to be only at least as good as its EF counterpart, that’ll be enough for me.
