I use the 24-105mm F4 L ISand the 16mm F2.8.
Very capable combination for traveling
I do not disagree but when traveling (walking) for birding I carry a D850 with 500 5.6PF in one hand and another in the other hand. This second camera used to be a 5DIV with 16-35 f/4L IS but it is a bulky combination as a concurrently second handheld camera. So I use 200D (=SL2) with EF-S10-18 and I also got a secondhand EF-S15-85. I would like to not have to also change lenses in that second camera....

Why not just use the RF 24-105 f/4 L? I own the RF 24-70 2.8 and didn't see much of a drop in quality each time I've used the RF 24-105, and the extra reach is really nice...
Yep, the RF 24-105 L is considerably better than the EF version, and as you say, not far off from the RF 24-70 L. Don't really see a need at all for an f/4 24-70. Just my opinion, though.

I have used the RF 100 for about a month and still have not found any issues with focus shift. Of cause I don't shoot test charts but flying bees. Maybe that's my mistake.:unsure:
Canon stated that the focus shift exhibited by the lens was a design trade-off with increasing the magnification to 1.4x. It’s definitely a real issue, not an Internet phenomenon.

Focus shift gets worse the closer your subject is to the MFD. It’s also aperture-dependent, and if you’re wide open or reasonably stopped down, it does not affect the image. I would guess that at typical flying bee working distances, you would not expect to have a problem with focus shift. It can be an issue in other used cases.

I would love to have a 20-70mm f2,8.
The 24-70 is fine for most situations, but often I find myself wanting a wider focal lense. It would be way more versatile in my opinion :)
For me the other way around, I would love to have a 35-105 f/2.8 more or less compact non-L non-IS as allways on lense, because the 70/75mm on full frame are often too short for me and 105 f/2.8 should also give better bokeh than 70 f/2.8.

Yep, I can totally attest to this.
