I thought it would be nice if they brought out the RF 100-400mm in the M mount as it would pair well with it. On reflection, f/8 is a bit too narrow for the very high pixel density of the M6 II and probably hardly better in resolution than your 70-300mm f/5.6.
That’s a real good point. For what it’s worth, all three of the posted osprey pix were f/8!
In my hands, the adapted EF 70-200 f/4 IS as well as the 70-300 f/4-5.6 IS II lenses are about as large (diameter and weight) on the M6MkII as I feel comfortable with, in terms of retaining the ‘compact’ feel that the M format offers.
I much prefer using (and traveling with) the EF 100-400 II when paired with a full-sized Canon body. But those require a much larger solution as far as a travel bag, case, backpack etc. are concerned.
I’ve had pretty good luck with the 70-300 IS II. I particularly like its focus capabilities. (I’m certain that when I go ‘R’ I’ll be blown away focus-wise…)
Pre-COVID (at least in terms of awareness in the western world), we traveled to Cocoa Beach FL exactly two years ago and the images in the link below were obtained, handheld, with the same body+lens combo as the osprey pictures:

So I’ve sort of settled on (air) traveling with the gear listed in an earlier post…and leaving ‘the big guns’ at home.
Maybe the R will change things
