A lot of Canon’s DSLR lineup is becoming a bit long-in-the-tooth. Canon hasn’t announced a professional DSLR body since the EOS 5D Mark IV in August of 2016.
We’re told that Canon will “likely” address the EOS-1D X line sometime in 2019. If we had to guess, we’d say the 4th quarter of 2019 would be the earliest we’d see an EOS-1D X Mark III.
While the EOS R is obviously the future of full frame ILC cameras, there will be at least one more iteration of the EOS-1D X we’re told. The source mentions that “Full frame mirrorless isn’t yet advanced enough to take over the duties of the EOS-1D line in Canon’s eyes”. I think in a lot of professional photographers would agree with that way of thinking.
We also expect to see a follow-up to the EOS 5D Mark IV before that line goes mirrorless. Though as previously mentioned, we think the EOS 5DS line is going to move to EOS R instead of a Mark II EF mount version.
Obviously, there weren’t really any specifications given for an EOS-1D X Mark III, but the source did claim that the new camera would have a new version of DPAF and other sensor technology. Though things like megapixels, framerates and video features are likely a long way from being finalized.
