It is designed for Canon RF mount APS-C format mirrorless cameras, where it provides an equivalent focal length of 45mm.
The f/1.4 aperture has maximum benefits in low-light conditions and provides extensive focus control for using selective focus techniques.
It has a high refractive index and is characterized by minimizing chromatic aberrations, and a Super Multi-Layer coating has also been applied to control lens flare in strong lighting conditions.
