Canon announces development of flagship EOS R1

Canon Inc. has announced today that it is currently developing the EOS R1, a full-frame mirrorless camera, as the first flagship model for the EOS R system. Whilst there is no timeline given for launch as yet, Canon has released hints of what's to come in terms of technology. It will use a newly developed processor, called DIGIC Accelerator, alongside the existing DIGIC X found in other R-series cameras plus a newly developed image sensor, which will enable a large volume of data to be processed at high speeds, and which will also deliver advances in autofocus (AF) and other functions as yet unspecified.

They herald the arrival of the next generation of Canon's sensor-based focusing system – Dual Pixel Intelligent AF – as well as offering a raft of improvements over previous R-series cameras. The new features and the improvements alike are powered by a duo of DIGIC processors, one DIGIC X and one DIGIC Accelerator – and by Deep Learning, with the introduction of Action Priority AF for team-based sports. Both cameras sport brand new, purpose-made back illuminated stacked (BSI) sensors; the EOS R1 offers 24.2MP and the EOS R5 Mark II offers 45MP.
