Offering versatility and long
reach in a notably sleek form factor, the Canon RF 70-200mm f/2.8L IS
USM is a flexible telephoto zoom characterized by its bright design
and advanced optics. The constant f/2.8 maximum aperture suits working in
difficult lighting conditions and also enables greater control over depth of
field. A sophisticated optical design comprises a series of specialized
elements, which help to suppress a variety of aberrations throughout the zoom
range for well-controlled imagery. An Air Sphere Coating has also been applied
to suppress flare and ghosting when working in strong lighting conditions.
Balancing the distinguished optical assets is the Dual
Nano USM focus system, which delivers fast, nearly silent autofocus performance
with full-time manual focus override. An Image Stabilizer also compensates for
up to five stops of camera shake to help produce sharper handheld shots in
difficult lighting conditions. A unique Control Ring is also integrated into
the lens design for intuitive control over exposure settings from the lens
itself. Additionally, this 70-200mm is weather-sealed and has a fluorine
coating to protect the front and rear elements.
Versatile telephoto zoom lens is
designed for use with full-frame Canon RF-mount mirrorless cameras.
Bright f/2.8 constant maximum
aperture maintains consistent illumination throughout the zoom range and suits
working in low-light conditions as well as affords increased control over depth
of field for working with selective focus techniques.
One UD (Ultra-Low Dispersion)
element and one Super UD element help to minimize chromatic aberrations and
color fringing in order to provide greater clarity and color accuracy.
Two aspherical elements are used
to correct spherical aberrations and distortion for improved sharpness and
accurate rendering.
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.
An Optical Image Stabilizer helps
to minimize the appearance of camera shake by five stops to better enable
working in low-light conditions and with slower shutter speeds. Three distinct
IS modes are available: standard single-shot mode, a panning-optimized mode,
and a mode that only activates the Image Stabilizer during the exposure.
Dual Nano USM system utilizes both
a ring type USM and an STM mechanism to realize quick and accurate focusing
that is also smooth and nearly silent to suit both photography and video
applications. This focusing system also affords full-time manual focus control
when working in the one-shot AF mode.
Configurable Control Ring can be
used to adjust a variety of exposure settings, including aperture, ISO, and
exposure compensation.
Protective fluorine coating has
been applied to the front and rear element to resist fingerprints and smudges
and to make cleaning these elements significantly easier.
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 nine-blade diaphragm
contributes to a pleasing bokeh quality.
Removable rotating tripod collar
is included and benefits working with the lens atop a tripod or monopod.
