Comparison of primes on M6II and R, and general comparison of M6II with R

I don't have any numbers, but to me the difference is significant.

The M6II focuses faster, but for the sticking-with-the-subject-part of AF the R is better. The R will still leave you wanting the R6 though.

For speed: no. The R focuses slower. For sticky tracking the R is better, but worth it is something else.

Damn.. so i guess im skipping the R and go for the R6 then.. but hopefully IF a RP mk ii or R mk ii comes out before i achieve my R6 fundings and carries the dual pixel 2.0 like the r10,r7,r6,r5 and price is cheaper than the R6. That would be a great option for me (fingers cross) till then eyes on R6 i guess.. ( target mid of 2023)

Well, I wouldn't recommend the RF 85mm f/2.0 IS stm + R for events work. The body could AF a bit better, but with this lens combined I think the M6II + 56mm f/1.4 using the right technique (single point AF doing the tracking yourself with the touch screen) will give better results for AF.

If you want best AF the R6 would still leave you with the problem which affordable fast and accurate focusing prime you should get. If you're going with a different mount anyway the Sony FE platform might give you better options, especially when budget is a factor. A used A7III + Samyang FE 85mm f/1.4 or Sony 85mm f/1.8 might be the better option. The RF 85mm f/2.0 IS stm is a very nice lens with some strong points, but it's AF is not suitable for event work. I'd even prefer the M6II + 56mm f/1.4 over the R + RF 85mm f/2.0 IS stm for AF performance..

Tempted for sony since im upgrading from the dead eos M system anyway, basically is like starting new with all the fancy RF lens. But where im from, a7iii price is just a tad higher if not the same as the eos R and the a7iv is about 10-15% higher than the R6. Not to mention the sony ecosystem and outdated a7iii interface. So i think canon will be my main pick here (i do love and respect the capabilities for the sony system, not to mention the 3rd party accessibility unlike canon RF)

But since the 85mm f2 is not suitable for fast phase environment, any other recommendations? Like the sigma non art ef 85mm 1.4(a used art version is 50-60% more expensive than a brand new 85mm f2 LoL)

My used EF 85mm Art was 600 euro, whereas my RF 85mm f/2.0 IS stm was 680 euro new.

The Art focuses definitely better than the RF 85mm f/2.0 for events, but if you want to rely on eye/face tracking it's not always dead on.  My 105mm f/1.4 Art is close to perfect, but that's another price category and a less flexible focal length.

or the rf samyang 85mm 1.4

The 85mm Art is better.

or viltrox 85mm 1.4

I don't know this lens.

or better yet, just adapt the vietnam war tech ef 85mm 1.8 haha.

Probably not

I've heard that with the latest body(r6 r5) 3rd party lenses are buggy and not accurate although its fast in the focusing department.

My advice is steering you towards Sony for a reason.  Canon wants to sell you a 70-200mm f/2.8  to get all the AF goodness of the R6, or the RF 85mm f/1.2.  The 85mm f/2.0 has cr*ppled AF, and Canon is actively discouraging third party manufacturers to produce fast focusing affordable RF 85mm primes.

So if you are planning to shoot events with affordable primes the RF mount is the wrong platform for you.

I've tried the Tamron EF f/1.8 VC SP, the EF Sigma Art, the Samyang RF f/1.4, but so far there is no 85mm focusing as good as my EF 105&40mm f/1.4  Art and EF 24-70mm f/2.8 L USM mkII.

All in all it's the R6 + Sigma 85mm f/1.4 Art as kind of sufficient solution for AF without paying L prices against the A7IV + ... well, a lot of good light weight affordable fast focusing options there.  If your events are about shooting in the lowest light possible Canon is a bit better.  If it's more about accuracy and not the lowest light ever for a reasonable price the A7IV + affordable FE 85mm option is your probably the way to go.

Personally I'm saving up for the RF 50mm f/1.2 L  as the gap between the Sigma 40mm Art and 105mm Art is too big to make it work.  I'm giving up on the 85mm focal length. It will be 50 or 105mm for me.  The RF 85mm f/1.2 L is too expensive, and the 105mm Art is good enough, and sometimes a bit longer is a good thing.
