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. The Deep learning technology – first found in the current flagship EOS-1D X Mark III DSLR camera – will be embedded in the new EOS R1. Canon also mentions a new AF 'Action Priority' function, which " further recognises subject movement by rapidly analysing the subject's status ". This AI-based programming promises to predict the key activity in a match, there...

Canon announces EOS R1 and EOS R5 Mark II as next R system evolution

Canon has today launched two new cameras for the EOS R system – the EOS R1, a new flagship model to take over from the EOS-1D X Mark III, and the EOS R5 Mark II, the next iteration of the ever-popular 5-series. The two camera share much more than just a launch date. 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. Rolling shutter effect is reduced, significantly so on the EOS R1. In-camera there's also an up-scaling feature, giving users of both cameras the opportunity to increase res...
