Lensrentals has a teardown of the Canon EOS R Mirrorless Camera. Nicely engineered camera, albeit nothing out of the ordinary.
It was rather a boring disassembly, really, about what we should expect for Canon doing a Canon 6D Mark II quality mirrorless camera. It’s neatly laid out and nicely engineered inside. One thing that struck me is that it’s not very crowded inside there, or as we like to say ‘they left a lot of air inside’.
