Sports photographer needs help deciding on a lens for EOS R

[Lkcphotos31]

I am a sports photographer who currently shoots on a Eos R and an ef to rf adapter that connects to my ef 70-200 f/ 2.8 L IS USM, the first generation of 70-200. My current lens has a foggy not sharp look to it during low light so I am looking for a different lens, I cannot send it in for repair because it is too old and they don't service them anymore. I cannot decide between the rf 70-200 and the ef 70-200. If anyone has any advice let me know! I am also looking at a 24-105 f/4 for the upcoming basketball season so if anyone has strong feelings about this lens please share.

If you're using Google Drive then you can add the link in the forum and give access to anyone with the link.

Lkcphotos31 the google drive works but I only see a jpg in the drive. Can you drop a couple of the RAW images full size on the drive. 

Also, the image that is loaded, it appears that you are shooting from a low angle up and there are stadium lights directly behind the shot. The camera appears to be fairly close to ground level. Is this an accurate assessment? The fogginess that you are talking about could be/appears to be flaring or bleeding from the stadium lights.

this should work let me know if not. Why does the flaring or bleeding from stadium lights not happen with my other lenses?

Not sure for a fact that is what it is but on that specific shot it looks like it to me. Just an observation that it may not be a equipment challenge and more of composition challenge.When you use the other lens are you shooting from a low position into the stadium lighting? There are variables I can't see with the other lenses you are using but the one example image it seems fairly apparent to me. I could be wrong.

If you look at the second image you posted, I added it below, it appears to be straight on shot with the stands in the background, camera shoulder high and level, no fogging or flare in the image.

I too am thinking your 70-200 may not be faulty.I have the first gen (non IS) version.It flares badly in certain light.

Try looking through the lens towards strong light - if it's fungus or lens separation those should be quite obvious.Fungus looks like tiny branching filaments and can vary greatly in extent.Lens separation looks like transparent bubbles and usually covers the whole lens that's affected.
