the big question is what's your goal. if you are familiar with the superb quality of hasselblad system and you want to achieve the nearest possible from canon to satisfy your own high demands as well as your clients, then we can say we are on the same boat, but if you think the higher megapixel camera is an exercise to find some poor quality lenses a bit better than on 20 megapixel camera then let's produce thousands of silly articles about it, hey!

The M6 II does 32.5 MP 14 FPS with tracking. Assuming the total throughput would remain the same, this puts a 75 MP Canon at 6 FPS. If they can go beyond the performance of their ~ 1k M camera with what will likely cost north of 3k, we can expect very competitive performance I think.

If you take the raw burst numbers (30fps, 18MP), you get to 7FPS.

At the risk of digging up a dead horse argument between Alan and myself if he's following this thread...I don't think a "big" difference exists. Pic related. If I recall correctly the three panels are 5Ds, 5DsR, and 5Ds with very light sharpening.

that's the wrong way around it. the 5dsr is actually a camera without the blurring filter (high pass or whatever it's called) that 5ds has. it was a terrible idea from canon and they will not repeat this mistake again.
the example picture can prove anything as it was done with a soft lens. try to put on your 5dsr for example sigma 50mm 1.4 art. step it down to F4 or 5.6 and photograph some sharp texture on iso 50. then try to do the same with 5ds and and any kind of sharpening. I guarantee you won't achieve the same result.

my good friend, a studio photographer, specialising in whisky bottles campaigns, bought back then 5ds. I told him to give it back to the shop and take 5dsr as this is the very essence of the high megapixel quality, he said he's very happy with 5ds so I proposed to do a studio tests and brought my camera for comparison. he had his 5dsr the next day.

Spoken like somebody who believes a half stop or less of DR difference will take your images from crap to fab....... Trust me it wont. If your images are crap on a canon they will be crap on a sony. So you may have wasted your money if that was the reason you changed

went from a 5D2 to a a7r2, and the image quality is pretty significant at an 1800$ price range. now it's just waiting to see if they replace the 5Dsr with something that can compete with the a7r series. i can hope they will and i can start investing in their new lens line. until then i'm happy with my sony and shooting with canon glass.

Obviously you haven't seen the quality of the 5d4 sensor . DR difference is insignificant. 90d and m62 have the best apsc sensor on the market. Canon are clearly caught up in the sensor game. And ahead in just about all other areas except for IBIS and eye af. Still way ahead on lenses and ergonomics. The only area where canon still lag way behind is in the youtoob 'influencer' telling popularity seeking enthusiasts how good the new tech, is in order to get sales from affiliate links. Although, having said all that I have to give credit to sony and the a7r4. It seems they have finally(after 10 years) learned that some photographers actually have human hands and want to hold on to their camera without the need for an on call doctor to fix the arthritis the camera gives them

It was done with a 50mm f/2.5 macro at f/8. You're kidding yourself if you think that lens at f/8 isn't sharp enough to illustrate any differences between AA and canceled AA sensors.

I guarantee you won't achieve the same result.
Exactly the same? No. Possible to tell apart at anything less than pixel peeping? I don't believe someone with 20/10 vision could pass that double blind test. I would complain that the 5DsR can show rough aliasing along edges when pixel peeping but in all honesty that's no more perceivable in print than any sharpness differences. There's very little to choose between them IMHO except that one is slightly less prone to full blown moire.

so I proposed to do a studio tests and brought my camera for comparison. he had his 5dsr the next day.
Good! Then you have RAW files to post so we can all see the difference and judge for ourselves if it's "big" or not. I hope I don't have to wait as long as I do for the DR examples I request from Sony fans ;)

Choose your weapons and we'll meet at noon.
If only we were YouTube influencers. I can see the opening scene now. A street in a dusty western ghost town. You at one end with a 5DsR, me at the other with a 5Ds, both with 100-400 mark II's. And the Northrups at either side, shooting drone footage and waiting to judge the results.

Forget it. I don't trust you to not whip out the 90D and win on pixel density :LOL:

You trust me too much - it would be at 100 yards with you a Colt 45 and me a Winchester.

This is the case on certain L brackets but when you buy a well designed model such as from RRS it will work.
I have the RRS L bracket on my R and it still limit the full tilt of the screen.

I would like to have a tilting screen. I hate articulated screens, very slow to handle and not so resistant.

When I'm shooting portrait view at low or high angles the articulated screen is amazing. A tilting screen would be useless.

There is a solution where you can have both; you could put the articulating part on top of the 'tilting flap', but this would be overkill. The articulating screen is the best solution to meet the demands of the many.

Regarding the IBIS story. I really like the Canon approach now. I have the RF 24 70 IS, stabilization is already amazing. Can't imagine how good it would be when they combine it in an IBIS system that is tested and proofed as Canon tend to do with their products.Of course it would be nice to stabilize a RF 50 1.2 already, but just have to be patience for a while.

Why should anybody else do that if you don't?

I don't take anybody seriously who doesn't post before and after images to illustrate their points when they make assertions about the differences they get with specific cameras, lenses, software etc.

You can choose to disable IBIS if you need.

Nobody will seriously buy Canon R and RF lenses if no IBIS.
I would buy it with or without ibis
2fps with tracking or can they at least get it to 5fps. If Sony can do 10fps at 61MP, surely you'd be targeting 6-7fps with 75MP. Three generations of digic later than 5Ds, should easily cope with 75MP.
Doesn't the a7Riv drop the bit rate in that burst mode? I'm pretty sure there are some considerable sacrifices to get up to 10fps. I guess it's still useful to get up to that speed when you really need it, but for most applications I'd probably stick with the lower speed and higher bit rate. To each their own though!

well... my advice was from one professional to others, take it or leave it. good luck with whatever you do

f/8 is above the diffraction limit of f/6.7 for the 5DS and 5DSR and both are being limited by diffraction. You lose a lot of resolution between say f/4 and f/8 - see for example measurements on good lenses like https://www.opticallimits.com/canon_eos_ff/964-canon35f14mk2?start=1 and https://www.opticallimits.com/canon_eos_ff/1000-sigma85f14art?start=1
You need to go down to f/4 or wider lenses to get the benefit of the R or see the difference. At f/8, there is indeed little benefit having the 5DSR over the 5DS. I am keeping my 400mm DO II f/4 for use with high resolution sensors.
