I agree with Brant. Just got my EF 24-10/ tuned up an ef 70-200 ii fixed. Very much enjoyed the cpl in the drop in.
I am going to be testing the 100-500 against the tamzooka. I know the tamzooka is weak at 600, but at 400 it is quite good.

What convinced me to go with the 24-70mm instead of waiting for the 28-70 f/2 came down to just a few things.
The 28-70 would be like having several primes, but the only prime in that range that I really use is the 35mm F/1.4L II and I like using it at F/1.6-1.8. The 28-70mm would be like a slower prime all across the range.
In older versions of the 24-70 the lens wasn't as sharp as it is stopped down, but the 24-70 II was sharp at f/2.8 and I believed the RF version would be to. So at all the other lengths the f/2.8 will be fast enough.
The final tipping straw to order it over keeping my the EF 24-70 II is the fact it has IS. Without flash shooting family pics at night the IS might be nice, and the holidays are coming and the lighting will be by X-mas tree.
How about the 100-500mm, is it worthy?
Would it be similar to owning the 100-400mm, or substantially better?
I have only used the RF 100-500 (borrowed Joel's for awhile at Laguna Seca). So most of this is based on a review of specs, and reviews. Just to get this out there, but a common reason that will apply to all of these the fact that I still have the 5DIV as my second body and my wife shoots an 80D, and while she has a EFs 15-85 and a EFs telephotos but still borrows my EF glass, especially the telephotos, when she shoots. So I am not ready to exchange EF for RF. At this point, it would be in addition too in many instances.
The RF 100-500 is slightly sharper, gives you that extra reach, but the big selling point is that it is lighter in relatively the same size. I'll almost certainly upgrade to the 100-500 at some point, unless something faster/more reach but still versatile gets released. Was it "substantially" better? It was substantially lighter, that was noticeable the second I swapped lenses. Bryan's "in-use" weight is only 90 g different, that doesn't include the converter, so ~220 g w/ converter. I do wonder if the weight of the 100-500 is better balanced as it felt like more than 1/2 lb. The bit more reach was noticeable. In terms of IQ, I've seen comparisons, I can see it, the RF is sharper but on that day, both lenses generated great images.
Swapping the 24-70 f/2.8 (EF Mk II vs RF). The biggest things that have caught my eye are sharpness at 50-70 mm (win for the RF), IS and weight. Again, I've seen real world comparisons, I believe the RF is just a hair shaper at those focal lengths. That would be nice. Regarding IS, looking at Bryan's IS tests with the RF and they are only a little (~1 stop) better than I get with my EF lens (IBIS). Avalanche Falls (1.3 sec) in the monthly was not shot with a full tripod. Those shots were either using a tripod as a monopod or resting on the guard rail. From Banff, I already posted a 0.5 sec handheld image. I took 3-4, all were sharp. Weight, the RF is ~100 g heavier. With converter, they are essentially the same weight.
So, from above, you mention that IS was a primary reason for switching. I do think IS+IBIS is better, but maybe only ~1 stop. If you still have your EF 24-70 II, you might want to try IBIS only (making sure it is on, Picture/camera tab 7, mine was off when I received it). Or maybe the sharpness at 50-70 mm is noticeable? I'd be interested if it is.
If you have both 100-500 and RF 24-70, then, so, you can start leaving the converter at home, which saves 130 g.
Initially the difference I see are so subtle that it might not be worthwhile for most people. The 24-70 II is going for about $1300 used, and it is an extra $1100 plus tax to switch.
The RF version actually feels a bit larger on the camera than the EF version with adapter even thought it is not. Size is a wash.
Looking at Bryans image charts I am not seeing much difference in IQ. Keeping in mind all the comparisons are either higher resolution or lower.
From what I have seen so far they are about equal as far as sharpness all the way through. I would have to set up some home made tests to compare.
Honestly it is a questionable upgrade for most people.
I consider both the RF 24-105/4 IS and 24-70/2.8 IS to be viable choices for an R-series standard zoom. In the EF-DSLR world, the 24-70/2.8 II offered overall better IQ and better AF performance (on bodies with f/2.8 AF points) than the 24-105/4, at the cost of IS, zoom range and a stop of light. For RF, the lenses are fairly similar in IQ (Bryan indicates they trade off through the ranges), there’s no special AF performance advantage at f/2.8 on a MILC, and both have IS. So it really comes down to one stop of light vs. a broader zoom range. Even subject isolation is similar at 70/2.8 and 105/4, if you have room to back up (although perspective will be a bit different).
Now throw the 28-70/2 into the mix. On a body with IBIS, the lens delivers the same (specified) 8 stops as the two IS zooms. I agree that the 28-70 is more like a ‘collection of primes’ than a zoom lens, and with my f/1.2-1.4 primes, I generally shoot them between f/1.8-2.2, so the 28-70/2 would actually serve that purpose for me.
If I had to choose just one of the three, the 24-70/2.8 would be an easy choice. However, I already have the 24-105/4, and that doesn’t combine very well with the 24-70/2.8 because there’s lots of overlap. The 28-70/2 would make a better ‘partner’ for the 24-105, so at this point I’m leaning that way.
The 100-500 is an excellent lens. I think Brant nicely summed up the comparison to the EF 100-400. In my case, I sold the 100-400 soon after getting the 600/4 II, because I used that when I needed reach and used the 70-300L as a compact option. Swapping the 70-300L for the native 100-500 was an easy decision for me since I’ve been using the adapted 70-300 on family walks and feel the need for more reach while not wanting to carry the 600/4 and manage kids.

I agree with Brant's summary too.
When we swapped lenses for a while at Laguna Seca the images I took with his EF 100-400 II were perfectly sharp and I would not say there is enough difference in sharpness between it and the RF 100-500 to entice anyone to switch.
The primary advantage is the extra 100mm of reach and secondarily the weight and balance.
Ok, so I've decided to get the RF 28-70/2. Now I just have to find one in stock...
I am sure there is a RF 28-70/2 floating off the coast in a cargo ship just waiting to come your way.
