Well, this is kinda strange. For a long time, there have been rumours and whispers of an impending mirrorless flagship from Canon to replace the EOS 1DX Mark III. Everybody naturally assumed that it would be called the Canon EOS R1. It turns out, though, that it might actually be the strangely named EOS R3 instead.
Nokishita, who is often right about these sorts of things, has posted an image to Twitter of an EOS R3 mirrorless camera that features a built-in vertical grip. Yes, the kind of grip we’d associate with a flagship body like the 1DX Mark III. They also say that it will be announced soon – at least a development announcement, if not a release.
