Canon 2x Teleconverter
This TC works only with a select group of Canon lenses, including the Canon 70-200 f/4 L and 100-400 L. Works well with no noticeable degradation of image quality. However, the laws of optics dictate that an F/4 lens becomes an F/8, or the 100-400 becomes an f/11. The camera body’s autofocus will be affected. On a 7D mark 2 may only have the center AF point functional, or have to use Live View with the camera on a tripod. On an R mount camera, you should have pretty much full AF function.
