Canon May Release a New Telephoto Lens To Rival Sigma Every other month, we come across patents that could result in the development of a new lens. Some are created for research purposes, while others tend to result in real lenses much later. However, there are other instances when you hear reports of launch dates, but they never truly materials. An example is Canon RF 200-500mm f4L IS USM, which we have reporting on since 2023, but there has been no official launch. But now, there are other articles which hint at the launch of another focal range, which could rival Sigma.
