There's an article on Luminous Landsdscape about the Canon R, and this caught my eye say...
"Michael and I have a conversation about his use of the Canon R for an extended time. While many of us were critical of the camera when we first saw it, it seems that the Canon R is a camera that needs to grow on you. Michael likes it and made some really good use of it."
I'd say that any new thing needs time before an informed judgement can be made unless there's some obvious issue such as a serious limitation or missing feature or ability. Looking at some of the repeated criticisms of the Sony A7x series including the menu, the colours and the ergonomics maybe these things are things that need time to grow on you too.
And before I get accused yet again of being a Sony fanboy (in a Sony thread) by Swiss Tony or some other forum semi troll I'll add that I agree with the comment on LL and the reason I'm bringing Sony into it is I've never really understood some of the criticisms as IMO they're often issues which could will melt away over a fairly short familiarisation period, same for other brands and models too I'm sure.
