The Canon RF 50mm f/1.8 STM is a compact and lightweight prime lens that offers a classic and versatile field of view, making it an excellent choice for everyday photography. Its sleek design is particularly suited for walkaround shooting, and it excels in available light conditions due to its bright aperture and effective depth of field control. The lens features an optical design that includes one aspherical element, which helps to minimize spherical aberrations and distortion.
