See my 135mm shootout thread for details on the methodology, but I'll summarize here:
These are 55 lp/mm charts, which make the black lines about 2 pixels wide on an R5. This target has detail that is totally invisible unless your final image is reduced less than 4:1, and really only if reduced less than 2:1. So even if a graphic here looks "bad", remember it's a level of bad only visible if your image is 4000-8000 pixels wide...
I shot each lens 10x at each of about ten shutter speeds. I had software score the sharpness and sort from sharpest to blurriest. Each line has a benchmark at the left and right to help you compare against "best."
CONCLUSIONS
The 100-500 actually has better IS at 1sec, but from 1/8 sec up, the sharper Macro optics pull ahead.
The 100-500 is so sharp (at least in the center) that there's really no need to switch to the 100 Macro at all, even if you suspect you'll be using the full 45MP.
And for either lens, shooting at 1/2 or even 1 sec is going to be fine for most purposes. Worry only about subject movement, not camera shake.
(I'll post the 24-105 results tomorrow.)
