Pairing a cherished
short-telephoto focal length with an exceptionally bright maximum aperture,
the Canon RF 85mm f/1.2L USM is also characterized by its
advanced optical design to produce well-corrected imagery. The fast f/1.2
design excels in difficult lighting conditions and also benefits working with
shallow depth of field and selective focus techniques. The optical layout
incorporates a Blue Spectrum Refractive Optics element; a specially developed
element that helps to nearly eliminate chromatic aberrations and color fringing
for notable clarity and color accuracy. In addition to this, an ultra-low
dispersion element and one aspherical element are also featured to further
control various aberrations and distortion for great sharpness and resolution.
Individual elements also feature an Air Sphere Coating to suppress flare and
ghosting for high contrast and color fidelity when working in bright and
backlit conditions.
Complementing the imaging capabilities is an apt
ring-type Ultrasonic Motor, which delivers fast, near-silent autofocus and
full-time manual focus override. A unique Control Ring is also integrated into
the lens design for intuitive control over exposure settings from the lens
itself.
Portrait-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.
Blue Spectrum Refractive Optics
element virtually eliminates color fringing and chromatic aberrations by
refracting shorter wavelengths of the visible spectrum (blue light).
One aspherical element and one UD
element also help to control aberrations and distortions for sharper, clearer
image quality.
An Air Sphere Coating (ASC) has
been applied to lens elements to reduce backlit flaring and ghosting for
maintained light transmission and high contrast in strong lighting conditions.
Ring-type Ultrasonic Motor (USM),
along with optimized focusing algorithms, a high-speed CPU, and an internal
focusing design, 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 9-blade diaphragm
