Canon RF 50mm f/1.8 STM Lens (Canon RF)

The Canon RF 50mm f/1.8 STM is a compact, lightweight normal-length prime lens designed for full-frame Canon RF-mount mirrorless cameras. A modern evolution of Canon’s classic “nifty fifty,” it provides a versatile, natural perspective that is ideal for everyday walkaround photography, portraits, street shooting, and low-light scenes. Featuring a bright f/1.8 maximum aperture for shallow depth-of-field control, a precision-molded aspherical element for sharpness, an STM stepping motor for smooth AF, and a customizable Control Ring, it combines portability with high optical performance.
