What's the difference between Canon rf and ef lenses?

The difference between them lies in lens interface, lens structure, lens quality, scope of application, price and compatibility.

1, lens interface: the EF lens uses Canon's own EF interface, and the RF lens uses a brand-new RF interface, which are incompatible.

2. Lens structure: The design of RF lens is more modern and concise than that of EF lens, so it is more compact.

3. Lens quality: Because RF lens adopts more advanced optical technology, its optical quality is higher than that of EF lens, which can provide higher resolution and contrast.

4. Scope of use: EF lens is widely used in Canon Quan Huafu and APS-C cameras, while RF lens can only be used in Canon full-frame cameras.

5. Price: Because the design of RF lens is more advanced, its price is higher.

6. Compatibility: EF lens cannot be directly installed on RF lens, and vice versa.
