A body cap is a very common accessory that every camera owner has. But here is a new patent from canon that will make this common accessory, special.
Recently canon filed a patent for a new camera cap that will clear the contact marks on the lens mount. Since a long time camera caps were used for just protecting the camera sensors from unwanted touch but the new and innovative design developed by canon will surely benefit the user by reducing the extra labor of cleaning the contact marks. Every time the cap is removed or attached to the camera body it will clean the marks.
