NO articulating screen is a great feature

They have made nice refinements, love the touch screen, love the multiple user menu windows, love that the chip is much better than previous versions and these cameras are pretty bomb proof

Fixed Screen - Many are screaming for the great new touch display to be articulated, but I'll take having the camera built like a tank over that feature any day

I really don't think it's that hard to make a robust flip/tilt screen that's suitable for a professional camera

The 5D IV does have a pretty cool new screen that only shows what you really need when you are shooting which is Shutter Speed, ISO, Aperture and focus point

I also feel like the buttons and dials are less responsive and the screens aren't nearly as good

Touch screen very helpful, especially touch to focus for video.

Improved focusing system- Touch screen

The touch sensitive screen is a great enhancement

The screen is excellent

The screen is nice and bright with an incredible resolution and a beautiful color space that makes reviewing images on-the-fly easy to do

I found I do more focus and re-compose with the 5D Mark IV.- Lack of articulating screen

The screen is much sharper and you can see what's in focus on the Mark IV.

Love the touch screen, it makes it so much easier

Information Screen - I haven't seen anyone mention yet the cool new information screen

Seems to me that Canon wanted to protect the 5DS/R from being cannibalized from a too potent 5DIV

Already the 5DS/R got improved
