Among the current Canon RF mount lenses, there is already an RF24-240mmF4-6.3ISUSM, which has covered most of the commonly used focal lengths. But what if you think the telephoto end is not enough? Foreign media recently exposed the patent of Canon’s RF24-300mmF4-5.6 lens. Generally speaking, Canon’s patents will be transformed into official products within one to two years, and foreign media claim that this lens may arrive in 2022.
