The difference between rf and rf-s

RF lens is more flexible and more suitable for novice photographers. Moreover, RF lens is a specialized micro-system with short flange distance, so it is more professional in shooting details. More importantly, it broke through 8 electronic nodes of EF lens and increased to 12 electronic contacts, which greatly accelerated the information transmission between camera and lens and significantly increased the transmission volume.

In film and television, the lens has two fingers, one refers to the optical components used by film cameras and projectors to produce images, the other refers to the continuous picture taken from power on to power off, or the fragment between two editing points, also known as the lens.
