RF 24-105 f4-7.1 vs RF 24-70 f2.8 in daylight

[Salamander]

I currently have the R6ii with the RF 24-105 f4-7.1 lens. I’m considering getting the RF 24-70 f2.8. I know the 2.8 will be better in low light. I’m curious if there is much difference in the quality of pictures taken outside in daylight, particularly as you zoom towards 70mm.

Daylight, so maybe say, "F/8 and be there." I presume you mean the RF 24-70/2.8L IS USM. In the center of the frame at 70mm f/8, the L-series lens is a little sharper, away from the center of the frame the L lens is noticeably better.

If by some chance you mean the non-L 28-70/2.8 IS STM, you can compare that lens using the above tool as well, and run through more focal lengths and apertures if you like.
