R7 for wildlife/action; USM or STM?

My R7 arrives in a couple of days, and I am debating the 600mm f.11 (STM) vs. RF100-400mm (USM). Forgetting all other considerations (reach, f stop, weight, versatility, etc.), WHICH LENS TYPE would work best. Informed opinions welcome, actual experience invaluable.

I have the R7 and R10 with both of those lenses.  Each has it's own use.  The RF 100-400's AF is faster, but not by much.  But you also need to keep in mind that the other is a 600mm lens and the focus will be a tad slower.

The good point on both lenses is that the AF on both, so far, has been very accurate and fast.  The AF on the 600 f11 is faster than some earlier STM lenses and it's super quiet.  Either way, you will be happy with either lens on the R7.

The reason I have both is for versatility.  The RF 100-400 gets more use, but the 600 f11 comes in so handy when I'm shooting farther away wildlife.

I have the 800mm F11 STM. Works great on R6. On r7 it works well as far as AF speed and accuracy is concerned. The bigger challenge is the diffraction issue.

For me rf800 is for R6, rf100-500 for both R6 as well as r7.

My experience is on the RP, but I rented the 600 for a vacation and now own the 100-400. For me, there wasn’t enough difference in AF to worry about. The 100-400 is definitely snappier. It goes goes from out of focus to in focus in a snap.

As far as owning, I value the versatility of the zoom range. If I want close to the same reach and keep the versatility, someday I can add the 1.4x and end up with 560mm at f/11 at the long end. With the ability to step down (not that I’d ever do it).

600 f/11

400 f/8

Thanks for a great reply. Now another question: do you use either/both teleconverters with either setup? If so, how are they working and which setup do you prefer?

I had the RF 1.4x TC and used it on the 100-400.  It delivered great results on the R6, but I no longer have it.  It should product very good results on the R7.  I wouldn't use it on the 600 f11 as now you're looking at f16 or so.  I like having both lenses, as the 100-400 is very versatile while the 600 prime also has it's uses.  I doubt I'll be getting the TC again anytime soon.
