You need to upgrade your R5 II to an R1, where the diopter dial must be pulled out to unlock it. Unfortunately, that’s a somewhat costly firmware upgrade.
The cost is not the issue, but my carrying mode. Peakdesign clips on each backpack strap. Each with a camera, right hand: RF 100-500, left hand: Leica M +35mm or EOS (to be defined + 15-35)
Otherwise, I would "long ago" have been an R3

owner, and have bought an R1

, despite its unusable horrible only 24MP.
I'm quite happy with 45MP, but I wouldn't say I need them.
But I miss the R3/R1 ergonomics, to me, they matter much more than a few MP more...
And presently, good old 3M have excellent adhesives...also for this stupid stills/video switch.
Yet, the R5 II is a great camera!
Edit: I forgot! The R1's world best EVF! This is a feature that really matters!
