Using Older Canon EF Lenses and 3rd-Party EF-Compatible Lenses with Canon R7: I have a question primarily for UHH'ers who own a Canon R-series camera. I'm again considering purchasing...

I have a question primarily for UHH'ers who own a Canon R-series camera. I'm again considering purchasing a Canon R7 with the 18-150 kit lens, planning to add some lenses in the future. However, I have been using a Canon 7d Mark II for some time, and have 7 EF-class lenses I use with it. All are about 10 years old. Here are the details on the lenses (plus a set of extension tubes):

Canon EF 50MM f/1.4 Ultrasonic
Canon 70-200mm EF f2.8 L IS II USM
Sigma 10-20mm DC HSM
Sigma 150-500 mm f5/6.3 APO DG OS HSM
Tamron 90mm Macro Di SP AF f/2.8
Tamron 18 - 270mm Di II f/3.5 - f/6.3
Tamron SP 24-70mm F/2.8 DI VC USD
Kenko Set of 3 extension tubes - 12mm, 20mm & 36mm

I know these will physically fit on the R7 if I purchase one of the adapters Canon sells. But will they actually work with the camera? That is, are there some functions of the R7 that won't work with the 2 Canon lenses? Will the R7 even recognize the 3rd-party lenses? If so, will there be function limits? Will the extension tubes work? I'd appreciate any experiences or advice you can share.

Mine work with the Canon adapter* just fine. A bunch of EF Canon lenses and a Tamron 150-600 G2. I also have a third party EF mount ultra-wide that works, but it is a fully manual lens to begin with so "if it mounts it works".

* I have the basic version of the adapter, not the one with the extra control ring or the filter slot.

...and I have the version with the control ring. I have tried the Sigma 18-300 and Tamron 150-600 G2 with it and all functions fine.

My wife asked me why I got the basic one when I could have the control ring and my EF lenses working just like the three RFs I have for my R7.

I kept quiet and just grinned when she added that I was a cheap skate and since we can afford it (as I often remind her when she buys the cheap cuts of meat) why don't I get the higher end photo gear?
She has seen my new RF 100-500L and knows it is new but not that it came to over $3000 with tax and shipping. And I am not mentioning it until she picks the SUV she wants to replace her Honda Civic and I pay for it.
After asking why I got an SUV since I am now retired, she takes my SUV to go shopping, so I have convinced her to pick out an SUV for herself, and we will get it. She was surprised when I told her we could pay cash. She never pays attention to the bank accounts except the one she uses for the household stuff.

To tell the truth, I rarely use the ring.

I knew I wouldn't since I am so used to the EF lenses. So I got the $99 basic adapter.

The Canon lenses absolutely will work 100% perfectly. No limits whatsoever.
The others most likely will work as well. If they are working on the 7D there should be no problem.
The tubes should be no problem as they just transfer information.
I have found the control ring to be very valuable with my EF/EFs mount lenses and totally recommend spending the extra for it if possible.

Below link has a list way down in the article showing tested Sigma and Tamron lenses on the R7.

Bottom line I would not worry, Canon is the most compatible overall brand there is it seems. Try putting old Tamron and Sigma lenses on any Z camera let alone actual old Nikon lenses and expect them to work.
That is why they are holding on letting third party lenses become RF mounts until they can be assured the performance is there.

So far I have had no problems with my Sigma and older EF lenses with my R7. Some older lenses do seem to hunt sometimes and can be slow to AF. As for exposure I have had no problems. I also use the Canon basic adapter.

My 2 non L lenses work about the same but the 2 L lenses AF quicker for me at least.

Me too. Bought the control ring adapter but never use the ring. Never use the ring on my RF lenses either. Just old habits, I guess.

That may be as much the lens as the adapter.

See, there you go again. You could have simply answered the question but it seems to be some sort of insecurity of yours that you need to bash Nikon every time you post. It says a lot about you.

March directly to the Canon refurb sale site, see if the simple adapter is in a stock, then buy one. Done. Else, pull out a $100 bill and find one else where.

I have an R7 and have used a variety of Canon EF lenses with it, including the 20/2.8, 40/2.8, 50/1.4, 100/2.0 and 24=105/4L, with the adapter, and they all work just as well, if not better, than on my Canon 6D Mark II body.
However, I had a Tamron 400mm lens that would work on the 6DII without a problem and absolutely would not work on either the R7 or an RP body.
Thus, with Canon lenses, no issue. Third party lenses, not so sure.

I adapted my old canon lenses, most noticeably the 100-400 to my Sony with the Sigma adapter and it worked well . AF was slightly slower in less than optimal light but it stiill functioned well, on a Canon I would think it would work perfectly fine if it worked on your dslr.
