Distinguished by its speed,
the RF 50mm f/1.2L USM from Canon is a
desirable normal-length prime due to its versatile focal length and bright
f/1.2 maximum aperture. This fast design excels in difficult lighting
conditions and also benefits working with shallow depth of field and selective
focus techniques. The optical layout incorporates one UD element and one
aspherical element, which help to reduce both chromatic and spherical
aberrations in order to produce greater clarity and sharpness. A rounded
10-blade diaphragm also benefits bokeh quality to suit isolating subjects with
depth of field. Complementing the imaging capabilities is an apt ring-type
Ultrasonic Motor, which delivers fast, near-silent autofocus and full-time
manual focus override. Additionally, a unique Control Ring is integrated into
the lens design for intuitive control over exposure settings from the lens
itself.
Normal-length prime is designed
for full-frame Canon RF-mount mirrorless digital cameras.
Exceptionally bright f/1.2 maximum
aperture affords extensive control over depth of field for selective focus
applications and also benefits working in low-light situations.
One UD (Ultra-Low Dispersion)
element is featured, and helps to minimize chromatic aberrations and color
fringing in order to provide greater clarity and color accuracy.
An aspherical element is used to
correct spherical aberrations and distortion for improved sharpness and
accurate rendering.
Ring-type Ultrasonic Motor (USM),
along with optimized focusing algorithms and a high-speed CPU, is employed to
deliver fast, precise, and quiet autofocus performance as well as full-time
manual focus override.
Configurable Control Ring can be
used to adjust a variety of exposure settings, including aperture, ISO, and
exposure compensation.
As a member of the esteemed
L-series, this lens has a weather-resistant design that protects against dust
and moisture to enable its use in inclement conditions.
Rounded 10-blade diaphragm
contributes to a pleasing bokeh quality.
