Here are Canon’s MTF charts for your lens, with and without the EX 1.4 MKIII. As you can see, there should be a very small difference. So you’re using a lens, an extender and and EF to RF adapter. The stack up shouldn’t make any difference to the AF on a MILC camera, but I wonder. Have you tried manual focus with this combination yet?
Thanks for the charts. I haven’t tried manual focusing with this combo. I dropped my L to RF adapter and damaged the lock ring so I won’t be using the 100-499 anymore on this trip. I’ll be shooting the rest of my vacation with my RF 24-105 f4.

Didn’t realize you had an R, so we’ll have to look for another solution.

I'd take the free option first of posting unedited JPEG examples, being sure to store the files. There's also the idea of specifically testing a subject, with and without the extender installed, to assure you can consistently recreate the issue when testing specifically for the extender installed.
Once back home I intend to do some research and create testing as you mentioned. No intention to spend money till I’m sure of the problem. Making sure it’s not something I’m doing causing the problem.

Again. I’m away on vacation and won’t have the images for post till I get home. The EOS R does not have micro adjustments. I have Focal but since updating my os it no longer works with dlsr because I have to repurchase new version. They do not support due to upgrading my os. I refuse to reinvest especially since it’s useless for mirrorless camera’s.

I have the same lens and teleconverter and I've used them on my 7D mk II many times. I currently have that lens combo on my 90D and have used it on my 5DSr and 5D mk IV and 6D and M50 and a few others and have not noticed any significant degradation to the images. My friend has used the combo on his T5i and T7i without issues also. I'd have the teleconverter checked by someone who knows what they're doing, like say, a Canon service tech.
Will do that as soon as I return home. I’ll have B&H check it for me. Thanks for your reply.

Look at the firmware status of both cameras too. Update as needed.
Yes, I always update my firmware. I wish they would do more with the R like a few more features. I find the R lags a bit compared to a dslr. They say the R5 & 6 are noticeably faster.

I’ll check the manual when I return home in a few days. Although I do use center spot focus on the 7D ii. With the R I see no noticeable difference in acquiring focus and I always use servo mode with back button focus. Thanks for your informative input CHG_CANON. If I can’t get this to work to my satisfaction I’m contemplating getting the canon 600mm but also want to upgrade to the canon R6 or R5 if I can talk my wife into it lol.

For what it’s worth… I read somewhere once where it is important to connect the converter to the lens first and then connect everything to the camera. Don’t know if that could make a difference.
I’m currently shooting with the canon R so the converter needs to be on the lens first then the L to R adapter than all connected to the camera. I don’t think that is the problem but thanks for your input.

All guesses without samples. Could be several things, but since you are getting good photos with out the converter, it is more than likely the converter. Or movement. Longer lens more chance for movement, but that should show as Morton, not soft focus.

Don’t think it’s motion blur as I’m using a high shutter speed and the birds are stationary. I’d hate to think how bad it would be with bif

Teleconverters generally work best with fixed focal length lenses, not zoom lenses.
Canon claims it’s compatible with this lens.

Yes, buy the new Canon 100-400L Mk II lens and you will see a huge improvement on sharpness and focusing speed.
I have the version II lens. It’s been a great lens and I’ve had it for a couple of years so since I’ve gotten into bird photography I wanted to get closer and picked up the converter. It focuses just about as quickly with the converter but the images are not sharp with it.
