50-frame focus bracketing speed for EOS R5 or EOS R5 Mark II

[jabo]

I am looking for a camera system for outdoor macro photography and I think focus stacking (not too interested in-camera but using Zerene or Helicon) is essential nowadays. For a high success rate  especially handheld  but also on tripod a high frame rate is essential as it reduces the chance of movement (including wind). The best system in this respect is the OM-1 with its 90mm macro with almost 30 fps in bracketing mode but I don't like the colors and DR of the m4/3 cameras. All the FF cameras I tried were around 5fps so too slow for larger stacks. So I am looking for info about the bracketing speed (for instance how long for 50 frames in the bracketing mode). That will be likely also dependent on the lens used. I guess the main choice would be the RF100mm/2.8 except I am not excited about its weight and bulk.

That is quite difficult to have so many flowers behaving. If that sub sec means millisecond, 15 sec for each frame would be very impressive!

My guess is that it is 1/100 second for sub sec time original. About 150 milliseconds per frame, That was 8 frames in less than a second using EF16-35mm f/4L IS USM. I do not own a macro lens nor any RF lens. My point is that the time is recorded in meta data. The camera estimated focus distance of 0.43 meter for first frame and 0.7 meter for last frame. So far as I can remember, I used Canon DPP software to do the stacking for this one. I did not think that the other frames contributed anything useful, probably because at 24mm that lens changes composition as distance changes but i do not remember. For my camera, F/6.3 is the largest FNumber without small aperture diffraction blur.
