This Canon Patent Describes Canon’s Prototype 100-400mm Miniature Concept Camera

Back in February Canon showcased various concept cameras at CP+ 2019.

One of these cameras, the IVY REC, can now be funded on Indiegogo. Another of those concept cameras is a miniature camera with a 100-400mm telephoto soon (image on top).

Canon patent application 2019-0208134 describes optical formulas and technology of the 100-400mm concept camera. Interesting fact: the lens itself appears to be removable. This could mean Canon will make more focal lengths to fit on this diminutive camera.

The patent application also describes ways and methods to make those lenses smaller and lighter. For sure a welcome feature.

Canon Working On Triple Image Stabilisation System, Canon Patent Suggests

We already know that most likely Canon will feature IBIS (In Body Image Stabilisation) on future Canon mirrorless cameras (and maybe on DSLRs too). Canon execs confirmed it.

It seems Canon wants to do things right, as we are used to. Canon patent application 2019-0199930 (US) describes technology and methods to make three image stabilisation systems work together. The patent discusses how to combine lens image stabilisation, IBIS, and digital image stabilisation.

Another Canon patent application discusses how to make IBIS and lens IS work together smoothly.

Canon patent application 2019-087397 (Japan) discusses how to make IBIS (In Body Image Stabilisation) work with lens-based image stabilisation. Not an easy task, I guess.

This is not the first IBIS-related patent filed by Canon. It’s now safe to assume that Canon will indeed implement IBIS in a future mirrorless camera (both EOS M and EOS R?).

Given the quantity of Canon lenses with IS it was to expect that Canon is interested to make IBIS wok with image-stabilised lenses.
