I have my eye on one of these lenses since my RF100-500 is hit and miss in low light wildlife shots. In your experience will a f2.8 have an extreme difference in performance than the f4. Price difference is sure extreme.

Is 200mm long enough for wildlife, regardless of aperture? These 70-200 zooms can't be extended, so you only have the pixel resolution for cropping.

I take photos at an area where 200mm will just cut it. Granted, I'll miss some opportunities but in low light I usually don't bother with long shots. As soon as the light unproven I'll switch lenses.

I have the 2.8 on the R5 and for me the main advantage over the 4.0 is the Bokeh effects shooting wide open. When shooting out at 200mm both lenses are equivalent. Also, i find that for distance i always switch to the 100 - 500 and sometimes even with the RF 1.4 extender.

I have the RF 70-200 f:/2.8 and the RF 100-500. Both work with my RF 1.4 extender. I don't know about the 70-200 f:/4.

Although I don't physically have these equipment, the reviews from Day-1 of the RF 70-200 zooms have always indicated:
No teleconverters work with this lens. The RF 1.4× and RF 2× extenders both need to extend into the mount of the lens, and this lens has glass there so they interfere and won't mount.
So, we're all stuck wondering what you think you're doing.

Does f/2.8 actually work for wildlife?
I made the mistake of letting go a 70-200 f/4 and replaced it with the 70-200 f/2.8 II and I am not sure if the f/4 did not deliver better image quality. If you are already shooting with an R body chances are that you can push your ISO well beyond what you were used to shooting with your DSLR. Between the higher ISO capabilities of your mirrorless body and if needed the incredible ability of Topaz software to clean noise and sharpen your images.... I am not so sure that you really need a 2.8 lens, DOF I would think would be an issue while shooting wide open as well.

I don't know about wildlife, but I have the f/4 and love it. So small and light. great images.

What about an adapted used EF 300 f4 or 2.8 ??

Your 70-200 works with your extender? I've read the extender dies not work with that lens.

Canon says the same thing.

The RF 100-500 max aperture at 200 is 5.0 so you would only gain 2/3 stop with the f/4. I own the RF 70-200 f/4 myself. Its size and weight make it a joy to use and the IQ ain't too shabby either, but I can't say if it would serve your needs.

I waffled for days whether to buy an EF f/2.8 or f/4 70-200. In the end, I went with the lighter and less expensive f/4 II with IS, which never fails to come through. I still use it with an EF to RF adapter on my R5. Even though, I still occasionally wonder if….. but it soon passes.
