What does rf in lens mean?

The RF in the lens usually refers to the interface of the camera lens, which is a new interface in the camera lens industry in recent years. RF stands for Ring-type Filter Mount and is mainly designed to fit high-end full-frame professional cameras, such as Canon EOS R, Canon EOS RP and other models. The design feature of the RF interface is to integrate the advantages of large aperture, high resolution and long focal length. At the same time, since the RF interface is compatible with EF mount lenses, many Canon camera users can choose to make more convenient lens conversion between EF and RF to improve the user experience.

Compared with the EF interface, the advantage of the RF interface mainly lies in the design upgrade. The design of the RF interface focuses more on providing professional photographers with better shooting quality and better imaging performance. The advantages of the RF interface include higher clarity, better color reproduction, more aperture control and faster autofocus. In addition, the RF interface also improves the camera’s continuous shooting speed and shutter response time, which provides photographers with more flexible shooting space.

Since the RF interface is relatively new, it will take more time to gain market acceptance. But considering the advantages of the RF interface, it is suitable for a wider range of shooting fields and occasions. For example, the large aperture advantage of the RF interface makes it better used in low-light environments; the RF interface has more accurate and excellent picture performance in documentary photography and landscape photography. In addition, the RF interface also has higher color saturation and better detail performance. For portrait photography that wins with color and details, the RF interface is also a good choice.
