A new patent by camera maker Canon has revealed that the company could be working on a camera attachment for smartphones. A new patent application discovered by Canon News suggests that the company may be working on a camera attachment with a high-powered zoom lens.

As per the patent, Canon is looking to offer telephoto lens attachment that can improve the optical performance of the camera. The 3D render of the patent reveals a Canon PowerShot Zoom-like product along with an attachment that could fit in a smartphone.

The patent further reveals that the external zoom lens rotates around a hinge that allows it to fold away. It has a bracket to hold a smartphone. A report by TechRadar reveals more about how the telephoto lens might work in tandem with the smartphone. The phone and lens can be connected via Wi-Fi while the phone would work as a viewfinder and a remote control for the camera via the Canon app.

The focal length of the lens is not specified in the patent, but it is speculated that you can set the focal length to 400 using the Zoom switch. The mobile lens accessory features a power switch. As Canon’s new patented camera attachment for smartphones looks similar to the Canon PowerShot Zoom device, it might also be possible to shoot videos with the external lens.

Similar camera attachments for smartphones were seen before as Sony had launched QX10 and QX100 in 2013. If Canon’s patented device is launched, it will be interesting to see how it performs and adds value to modern smartphones which feature premium quality camera sensors.
