The Canon R5 Mark II launches in just a few days on July 17 - and Tony Northrup (via CanonRumors.com) has the leaked specs! Well, hopefully they're accurate specs.
Here's what we think the R5 Mark II will look like. CanonRumors expects the price to be $3,999 (sdp.io/R52):
45 Megapixels
12 FPS stills with the mechanical shutter or 30 FPS stills with the electronic shutter
up to 8K at 60 FPS video (probably raw internal)
Eye-controlled autofocus point selection, like the Canon R3
No EVF blackout
Improved PixelShift for high-megapixel images
Some illuminated buttons
Autofocus to -8 EV
Better battery life
Shutter speed faster than 1/8000" with the electronic shutter
up to 16 stops of dynamic range... WHAT?? I talk about this a lot in the video
New IBIS modes.
