Poised to be the new workhorse
zoom, the Canon RF 24-70mm f/2.8L IS USM is a versatile
wide-angle to portrait-length lens characterized by its bright, advanced, and
intuitive design. The constant f/2.8 maximum aperture suits working in
difficult lighting conditions and also enables greater control over depth of
field. The optical design incorporates a series of aspherical and Ultra-Low
Dispersion elements, which greatly reduce a variety of aberrations throughout
the zoom range in order to produce sharp and clear 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 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 24-70mm
is weather-sealed and has a fluorine coating to protect the front and rear
elements.
Standard wide-angle to 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.
Three UD (Ultra-Low Dispersion)
elements help to minimize chromatic aberrations and color fringing in order to
provide greater clarity and color accuracy.
Three 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.
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.
