EOS-1D X and the f8 issue

Auto-focusing may not function at f8 on some EOS-1D X cameras with firmware version 1.1.1. This version enabled the centre AF point to autofocus when the camera is used with lens/extender combinations, whose combined maximum aperture is f8.

On some of the cameras with firmware version 1.1.1, auto-focusing does not function at f8. This is not an issue with the firmware itself, but with its installation at the factory. The problem can be overcome by overwriting the firmware. This phenomenon does not occur with a camera whose firmware has been updated by a user, or by a Canon service center.

Cameras with 4 or 5 as the sixth digit from the left in the serial number are affected.

Even when the sixth digit from the left in theserial number is 4 or 5, cameras with a white dot in the battery compartment are not affected.

To overwrite the installed firmware and activate the auto-focusing at f8, simply re-install firmware version 1.1.1. There is no change to the firmware version, as this is not an issue with the firmware itself.

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...
