Inhouse product
Poised to be the new workhorse zoom, the Canon RF 24-70mm f/2.8 L 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.
