You seem to have sound logic in your presumptions.'R' for the EF-R lenses, with a Rear-projecting design that allows a more compact-appearing mounted lens with the standard EF mount, since part of the lens protrudes into the camera body.
Looking forward to native EF mount and small EF-R lenses with Dixie-cup rear caps.
No company is going to give it to you, you have to pay.I wonder which company would give us high resolution fast EVF first. Hopefully Canon would do it right.
I have spent years using a variety of different cameras, from film SLRs, film P&S to DSLRs including the 350D, 7D, , 700D, and 80D as well as mirrorless M10 and M5. This has given me clearly understood matrix of ergonomic parameters and experiences.
The 80D is the ideal size for me. The only ergonomic improvement, would be to add a thumb joystick (like the 7D), and shave off about 200-300gr of weight. The more I have used my M5, the more I appreciate its ergonomics in a small package (muscle memory being improved, etc). Though when I return to my 80D, I appreciate the more tactile and less cramped layout.
There is a place for both - the current 'DSLR shape/size' and the smaller EOS M size, in my humble opinion, particularly when one factors in the smaller EF-M lenses. E.g. when I want something small to have in my bag, my M5 or even M10 with my 15-45mm zoom or the the 22mm f/2 prime makes a great compact portable package, with very good image quality. However for longer term shooting, my 80D / 7D combination with a one of my EF/EF-S lenses does provide a more ergonomic (& responsive) package overall (e.g. the full day outdoor photo outings, or events I photograph).
I also really like the idea of Canon's new ("rumoured") mirrorless having a LP-E6N battery... I have a stack of LP-E6(N) batteries, most of them still going strong. Looking forward to Canon's offering coming up. I am sure they will provide a sensible, and well performing option / set of options.
After that the NEXT Canon camera is where the BIG GUNS from Canon are coming out because THAT ONE is Medium Format ............
REMEMBER! YOU HEARD IT HERE FIRST !!!
...because it could allow for new possibilities such as smaller light lenses, while still retain full EF compatibility thru an adapter. I'm not saying it would be the way to go, but it seems some people would not mind a new mount at all. I personally don't care much.And they think Canon would use a completely new mount because...?
I'd suggest the Leica SL, whose EVF is really excellent, even though I'd still prefer an optical (EOS) viewfinder.No company is going to give it to you, you have to pay.
Beyond that, define the terms (high resolution and fast). Then you can observe which company sells them soonest.
yes....I bought a Canon M5 and sold it soon afterwards for two reasons.
1. The EVF was terrible : small, laggy and very low resolution. I couldn't bear using it.
2. I was frequently accidentally pressing the menu button whilst trying to take a picture. Almost always.
The menu button is situated at the very bottom right of the camera.
With such a small camera there are very few ways of actually holding it and supporting it with a decent (i.e. heavy) lens.
And it turns out that when gripping the camera tightly you are quite likely to accidentally press the menu button whilst taking a shot.
This drove me totally nuts.
I am really quite astounded that Canon have continued to put such an important button in such a place .... pressing it whilst trying to compose a shot causes mayhem.
I honestly believe that this alone will be enough to sink the camera.
No doubt there are countless people who have adapted (consciously or otherwise) to this problem but I find it very, very difficult to believe that I will be in such a tiny minority that hardly anyone will hear about the problem.
Whilst I love the whole tilty-flippy thing it does seem to imply there are no buttons on the left hand side of the camera and this is a great loss I think. If they could find some way of combining the flippy screen with a column of buttons on the left that would be great ... but maybe its an either/or situation.
The resulting high density of buttons on the right comes with its own set of problems ...
