Canon Patent Application: Another IBIS related patent application shows up
Another IBIS patent showed up for Canon this week, and Keith from northlight spotted it pretty quickly. This patent, filed back in December 2017 shows an IBIS unit and deals with exposure variations that can occur if IBIS is actively doing pitch and yaw movements of the sensor and electronic front curtain shutter is also active.
As with other IBIS patents we've seen, the IBIS unit described is the same as prior patent applications. This can mean one of two things, they are just using a stock image and a couple of description paragraphs to save effort (altogether possible) or we do see exactly what the IBIS unit for the Canon EOS R will look like.
Interestingly, if you believe patent diagrams, it certainly appears like the camera in the above diagram is an EF mount mirrorless camera. If I had a guess, this is a pretty good indication that as of late 2017, Canon had no idea which way they were going to go .. EF mount or a new RF mount.
Also interestingly, the actual patent IBIS mechanism seems to be the same as the Panasonic IBIS unit described in this patent 2015-188199.
Only time will tell, but it's certainly looking like Canon a few years ago started in ernest the R&D on IBIS (which dispells Sony fans from stating that Canon (and possibly Nikon) didn't start a thing until the A7 III came out in early 2018)
