CR notes from the leaked images:
There is a normal 3-axis flippy screen
There is a new M-Fn3 button on the top left (below the menu button)
There are four playback buttons below the display: playback, magnifying glass, dustbin, rating button
There is a LAN indicator light
There is also this interesting window beside the LAN light. We can’ speculate as to what it might.
The INFO button now is built into the vertical grip as well.
The Viewfinder is a lot bigger than the EOS R3. The EOS R3 EVF is 5,760,000, the EVF on the EOS R1 looks like it could get has high as 10,000,000 dots.
The Joysticks and AF Smart Control are included, as we already know.
The multi-shoe has a locking cap.
The memory card door has a lock.
The EOS R1 is far bigger than the EOS R3.
A mounting lug on the bottom of the camera for a wrist strap.
Battery Percentage on the top LCD, not just the bars we have seen on other Canon cameras.
The top button layout is the same as on the R3, with an added White Balance Button
On the top are also two new symbols near the M-Fn button and the LCD-light button in a blueish colour: according to Tony Northrup the gas-station-like Symbol is the FTP-Symbol which indicates a dedicated button for wireless transmission. The other one shows a crop-symbol which might be a sign for a integrated teleconverter
The ON-OFF switch on the side, is for controlling the vertical grip functions and was used on previous 1D-series Cameras, but is not built into the EOS R3.
The card slot seems just a little bigger than on the R3 to fit Dual CFexpress Type B cards.
The bottom shows us an HDMI logo, so it features full HDMI.
A diopter control is also built into the viewfinder.
The mode-switch is the same as on the EOS R3 and EOS R5.
Overall is the camera bigger, but especially thicker than the EOS R3, that also improves the ergonomics.
The battery voltage is something over 10V. While the EOS-1D Mark III and EOS R3’s LP-E19 battery runs with 10.8V. The EOS R1 appears to show 15v on the identifying sticker on the bottom of the camera.
