Maybe you haven't bothered to learn to use the touchpad focus effectively.
I agree there 100%... I was reluctant to move from a Button like feel of the joy stick and went straight to the Dpad and that ring adapter convinced me it was a good idea. I have now moved to EVF and on screen for ISO and AF point movement. ISO is so slick using the function button right beside your main wheel and back to shooting very fast. It's all right there on your EVF you never have to look away from your subject. I think the R is about change... Some are very reluctant to change. Others embrace a chance to learn and have fun while doing so. I for one I'm glad its not a Sony look-a-like... I've used then and was more a tune to the EOS R.. In my opinion it works beautifully in its own right.
I have not found any problems with the Sandisk extreme Pro SDXC I or II cards I don't think while shooting I've hit the buffer while shooting for real. And I'm not shy with the shutter button. And if you think hitting Pine Marten running through the snow is a walk in the park... !! think again.
The two card thing is going to haunt those who care forever, Don't know what they did before the dual slots. Personally in the last 4 years I've had my 7DII set to only fill one then move to the other. Never has it written to both at the same time.. There's 5 4T drives plugged into my mac that say cards are quite stable if you take care and don't pull them without ejecting them properly... even by accident.
This camera gets easier and faster the longer you use it. Stay in yesterday.... move on to tomorrow... It's up to all of us to decide.
I've not had a over exposed Image out in the snow using this EOS R........ figure that... Its always exactly what I was intending.
Thought I would add a shot of the EVF showing ISO and how clearly one can see what it is you wish to change.
