The rumors about a high-megapixel EOS R5 have been around since the release of the camera. Most of us have reported a Canon camera with an 80mp image sensor, but by the sounds of it, Canon will take the resolution much higher.
A solid source has told me that Canon hasn't yet internally decided on which image sensor will come in the new high-megapixel RF mount camera. This camera will replace the equally loved and hated EOS 5DS and EOS 5DS R.
Apparently, the goal now is to be north of 100mp, to provide even more separation between the EOS R5's 45mp and the new high-megapixel sensor. The same source also mentions that it's not simply going to be an EOS R5 body with a higher resolution sensor, but a camera geared towards landscape and studio photographers. What that means ergonomically, I'm not sure.
More to come…
