Only if it's under 500g not bigger than the 24-105I see!

Even the RF 70-200 Z is 40% lighter than the EF variants and you don't need the adapter. Actually compared to the Z version and the new Nikon 70-200, the weight of the original RF 70-200 with the external zoom is not that impressive.The RF L is a great lens, optically comparable to my EF mkII, but a lot lighter and easier to carry in a camera bag. Loosing teleconverter usage is a bit naff though.
I’m with you there, I’ve also been rocking a mkII for a long time. Mine has a few battle scars, but still works great. I don’t think the new RF L lenses are as robust as the later EF lenses. Most of my lenses are over 15 years old and look pretty descent. Most RF casings look a bit shabby after 5 years of heavy pro use.I can certainly say that aside from some chipping paint, my EF 70-200 f/2.8L IS USM II is still going strong and certainly has some new life on my R5 ii. Hard to justify replacing that with a newer model to be honest.

Canon does not make it
I have this one too and I agree, I really struggle to justify getting the new one, no of my clients will be able to tell the difference in sharpness. The Mark II sells for just over $1K while the new one brand new is $4K.... The math doesn't add up... AUD btw.I can certainly say that aside from some chipping paint, my EF 70-200 f/2.8L IS USM II is still going strong and certainly has some new life on my R5 ii.

Protein science (at the interface of molecular biology, chemistry, biophysics and structural biology).Well done. What is your field of study?
Well done. What is your field of study?Please forgive a fellow experimental scientist for using your image to test those theories - after all as Max Planck wrote: "Experiments are the only means of knowledge at our disposal, the rest is poetry, imagination." (especially what's on Facebook).

Actually (and this is almost always missed), analysis of observational data precedes the generation of a hypothesis. The hypothesis then generates a testable prediction which can be verified or falsified by further experiment.It illustrates that it's the ambient light and the exposure that are doing the difference, no surprise...
But: "Experiments are the only means of knowledge at our disposal, the rest is poetry, imagination." I would say that the experiments start with "poetry, imagination.", usually called hypothesis.
And only the results from the experiments are the thing that will kill or uplift your hypothesis! In this particular case the hypothesis didn't survive the experiment. For the "experimental scientist" it means (most of the time but not always) your chances to get money for your next experiment are diminishing...
