Canon EF 24mm F1.4 L II USM

The Canon EF 24mm F1.4 L II USM was designed for demanding owners of Canon DSLR cameras. Its low weight ensures comfortable operation and manipulation. It features a large-diameter aspherical lens and UD lens elements to minimize chromatic aberrations. The floating system with floating lens elements provides high image quality at focusing distances starting at 25 cm. Internal focusing featuring a ring type USM and new AF algorithms allows for fast and quiet autofocusing. The USM uses a piezoelectric principle, consisting of two rings —  a stator and a rotor.
