To be clear, the EF lenses perform the same or better on the RF cameras. It's just that the RF lenses are that much better.

My last EF camera was the 6D2. And using the same 85 mm 1.4 on the 6D2 produced sharper results and better focusing on my RP or R5 than on my 6D2. It actually surprised me as I thought they should produce equivalent sharpness.
True that RF lenses perform better than EF ones but RF L lenses just cost way too much currently for my taste - main reason for my hesitation to switch out my EF lenses. And my EF lenses have been performing flawlessly on my R with the converter. YMMV.

So we have a baseline, I have the EOS R5 and the RP.

The biggest benefit is the sharpness. I have the EF 85 mm 1.4 and I bought that over the EF 85 mm 1.2 because the 1.2 was just so hard to use. The 1.2 was very slow to focus and was so hard to get consistent sharp results. The 1.4 was cheaper, faster to focus, and had IS. But the RF 85 1.2 is better in every way than the EF 85 1.4. In a high speed burst with the EF 85 1.4, I could miss focus for maybe 1 out of 4 shots such as a person walking down a runway. Sometimes as bad as 1 out of 3 or even 1 out of 2 if the lighting conditions were particularly bad. Even with the RF 85 1.2 at 1.2, I would have tack sharp images under the same conditions. It's pretty amazing. And the bokeh is just gorgeous. the 1.4 was no slouch but it's not comparable.

I could say the same with the 35 mm 1.8. corner to corner, it's sharper.

You can say that about the amazing 15-35 mm 2.8.

The RF 100 2.8 I would say it's not worth upgrading to. It's a good lens but not a noticeable upgrade.

The RF 70-200 is a practical upgrade. For one thing, it's super compact and can pack into a bag easily. Plus, you can get it into a sports stadium. For example, Dodgers Stadium has a 6" lens limit. the RF 70-200 is only 5.7 inches long. Once you pass the security, you can extend it to your heart's content.
Thanks for your comment. I have a related question: recently moved from EF (5D Mark ii) to RF (R6 ii). I own the EF 85mm L 1.2. When used right, it produces some of the best portrait pics, BUT as you said, it very slow. Would I see a marked improvement if I move to RF 85mm 1.2?

I have several EF lenses that I use with my current eos T2i.

Looking to go mirrorless.

Is the eos R with this adapter good to get me started?

Thank you

I switched to the EOS R when I decided to drop my D-SLRs and I think it is still decent.

I had a 5DSR and a 6D, and I found the R's AF performance notably more reliable for my uses, especially for shooting people. The DR and resolution were also adequate for my uses. Depending on price ofc, I still consider the R a great camera - if you don't care for the absolute best that is.

Used to have a lot of EF glass, but I use mostly RFs now, with the RF 24-105 f/4L being notably better than the EF 24-105s, and good enough for me to sell my EF 24-70L 2.8.

Still use the adapter (this specific one) for the EF lenses I did not drop (EF-L 100-400 II, EF-L 16-35 4 IS, Sigma 85A 1.4, Sigma 150 2.8 Macro).

If you are on a tight budget, Canon offers another (cheaper) adapter that doesn't have the control ring. The cheaper version can be bought for $100. And that's all you need to adapt your EF lenses on any R cameras.

I'm thinking about selling my EF 24-70 II for the RF 24-105 f4... just because the RF 24-70 is so damn expensive. I'm glad to hear its at least better than the old 24-105 - which I had and disliked.

Yes, IMHO the RF-L 24-105 4 IS is pretty decent, and I am comparing it to my decent 24-70 ΙΙ copy.

It is notably lighter, the extra reach & compression @ 105mm are also notable, the AF works faster (i think): it is a better walk-around/all around lens and I think it fits the profile of a grip-less R better.

The new RF glass seems to be better all-around, but the prices are just too high for my use. I know I would enjoy the RF 24-70 being a stop faster and having IS "and-and-and", but the 24-105 is "good nough".

I admire that you enjoyed the EF 85 1.2. I thought I would love it but it was just so hard to shoot with because I was just never used to such a slow lens. I couldn't justify spending more when it was so taxing to get great shots out of it. If I was more skilled, maybe it'd be a different situation.

However, the RF 85 1.2 is just so easy to use. You can run and gun at 1.2 and still get tack sharp images. It's really one of Canon's best lenses ever.

One negative thing about the RF 70-200 is that it cannot be used with a teleconverter. All EF 70-200 lenses worked great with both the 1.4x and 2.0x teleconverters.
I've never liked teleconverters so it wasn't an issue with me but yeah, that's a great point.

Thanks. Given I have now moved to mirrorless & the benefits of RF 85, it makes sense to sell the EF 85 ( & buy the RF version)- but man, they go for such a low price on the used market (given how much I paid when I bought new)

100% agree, I have both the EF and RF version of lenses and they are equally good except when I am shooting people, animal, or anything moving.

When you need to use the max burst, 12fps mechanical, or 20/30/40 fps electronics, only the RF lenses can keep up with AI object detection, focus, capture, and repeat. RF lenses give me 90-100% sharp focused results. EF adapted lenses give me roughly 50-75% sharp focused results (moving objects and people).

I was from 6D2, 5D4 etc and I only got 6-7fps or so (and not live view). So, 50+% out of 12/20/30/40 fps is at least as good as DSLR and that is the worst case.

So, adapted EF lenses will function better on R series cameras than they were on DSLRs, all the way to stretch their limits (you will hear the motor whining a lot). And when you need to up the game, you should make enough $$ to paid for the RF lenses.

I think it'd be a great start. I'm trying to be careful and not make it seem like EF glass is bad. EF glass is great but it's not as good as RF glass. However, people should upgrade at the speed (and budget) that they're comfortable with. RF glass doesn't make EF glass suddenly bad.

How much is the EOS R? Because the new EOS R8 is $1500 and might be better for you. In most ways, the EOS R8 is a better camera. the only advantages at this point for the EOS R is battery life, weather proofing, and a mechanical shutter.
