RF 24-70mm F/2.8 L IS USM Question

[HDNitehawk]

When we swapped lenses for a while at Laguna Seca the images I took with his EF 100-400 II were perfectly sharp and I would not say there is enough difference in sharpness between it and the RF 100-500 to entice anyone to switch.

It sounds like my debate to buy it is the same as I had with the EF 100-400 II. I gave the 100-400 I version to my brother when I bought my first 500mm. My thinking now is to upgrade to the 600mm f/4 and possibly buy the RF 100-500mm as a filler for the other ranges.

That is my current super tele set up. A few years ago I found a really good price on a used EF version II 600 f/4 and then added the RF 100-500 when I bought the R5. I still own all my other EF lenses too and I am very happy with their performance using an adapter.
