Description

Compact and lightweight, the Canon RF 45mm f/1.2 STM is an affordable prime lens with an extremely fast f/1.2 maximum aperture and a versatile 45mm focal length. Perfect for a walk around the park or a day in the studio, the lens offers exceptionally shallow depth of field and beautiful, expressive bokeh. Thanks to its wide-aperture capabilities and medium focal length, this lens is perfect for portraits, lifestyle content, and low-light work, creating soft images with dramatic focus falloff. An STM motor affords quiet and smooth autofocus performance and full-time manual focus override. The optical design incorporates one aspherical element, which reduces spherical aberrations and distortion.

Additional Details

  • Normal-length prime is designed for use with full-frame Canon RF-mount mirrorless digital cameras.
  • Bright f/1.2 maximum aperture suits working in difficult lighting conditions and also offers increased control over depth of field.
  • STM stepping motor offers fast, quiet, smooth, and accurate autofocus performance that is ideal for video recording as well as still shooting.
  • One precision-molded (PMo) aspherical element suppresses spherical aberrations and distortion for high sharpness and accurate subject rendering.
