Posting this specification list actually kept up last night (silly right?), as I find some of it too good to be true, but as a few of you mentioned on Twitter, this is a rumors site, not a facts site.
I received this information from two unrelated people, one of which I have had interaction with in the past, and I actually trust neither of them is trolling me in any way. Some of their specifications are slightly different, but they’re still very close.
One of the sources did mention that the camera may be called the EOS R5, and not the EOS RS, as the model name “was hard to see”.
The video specifications only came from one source, and they are insane. These are what really caused me to pause, but hopefully, this post brings some clarification.
Canon EOS RS Specifications:
45mp (One source said 40mp)
5 stops with IBIS alone
7-8 stops of correction when used with in-lens stabilization
14fps / 20fps (One source said 12fps / 20fps)
Scroll wheel added to the back
