Core Concepts: Aperture, Focal Length, and USM

Understanding aperture, focal length, and USM is crucial for appreciating the Canon EF 50mm f/1.2L USM lens. Aperture, measured in f-stops, controls the amount of light entering the lens. A wider aperture (smaller f-number) allows more light, enabling faster shutter speeds and shallower depth of field. Focal length determines the angle of view; a 50mm lens offers a natural perspective. USM, or Ultrasonic Motor, provides fast, silent, and precise autofocus, essential for capturing sharp images of moving subjects.

Why the 50mm f/1.2L Matters Today

Despite advancements in lens technology, the Canon EF 50mm f/1.2L USM lens remains highly relevant.
