I cannot understand why they made such drastic physical changes to the R bodies? Through decades of evolution from customer feedback, we have almost perfect camera bodies. Everything we need is under our fingertips! The changes are minimal at best between the old and the new because it has been perfected. The operation of EOS cameras has become standard throughout most of the lines. Pick up an EOS Camera that you are not familiar with and you have a pretty much seamless transition to it with all operations. The similarity inherent in each camera line with button placement for instant changes of the critical settings is ingrained in all of us. Buy a brand new Rebel and it operates almost exactly like all Rebels from the past, The same goes for the XXD line and the XD line. Just look at the new 1DX MKIII compared to its predecessor(s). Again the differences are minimal. Why? Again, its because it has been perfected. Photographers simply can just go to work. They brought out the R System and most of the buttons are gone. Why start from scratch? Why destroy what you have worked so hard perfecting over the years because you removed a mirror? I can only hope they go back to the layouts of the EOS System we all have come to know and love. Critical settings buried in Menus are for smartphones! Then you have the size. Why do so many people want tiny cameras? Sure if you want to go light then have a camera or two designed for that purpose. I would much rather have a little larger camera that I have familiar access to a full set of controls at my fingertips than a dinky little piece of crap that I have to take my eye away from the viewfinder and start searching menus! I mean the XXD camera line is certainly small but you do not give up anything when it comes to operation or comfort. None at all. What say you?
