Of course, the design has its peculiarities. One is that the camera’s shoe (the component labeled “P” in the top diagram) would become unusable in the gadget’s selfie orientation. For a camera built around vlogging, this would not be ideal; most external microphones connect to a camera via their shoe. There is also no mention of gimbal support in Canon’s documentation, which means that any stabilization would have to be provided by a potential mechanism in the body and through the lens. Using Canon’s full frame glass would also pay off. RF lenses are not the lightest (or most affordable) lenses you can buy and the resulting camera would probably not fit in your pocket.
As with all patents, this may not lead to a product that you can buy. However, as Canon News points out, the company has filed five separate patents related to this design, which indicates that the idea is at least serious.
