CANON RF 28-70MM F/2L USM OVERVIEW
Combining the versatility of a zoom with the speed typically
reserved for a prime, the Canon RF 28-70mm f/2 L USM is a wide-angle to
portrait-length lens distinguished by its impressively unique f/2 constant
maximum aperture. This bright design yields excellent low-light performance
along with enhanced control over depth of field for isolating subject matter.
Ultra-Low Dispersion glass is employed in the optical design, and greatly
reduces color fringing and chromatic aberrations in order to realize high
clarity and color accuracy. Complementing the advanced optical properties is
Canon's proven ring-type Ultrasonic Motor, which delivers fast and quiet
autofocus performance along with full-time manual focus control. Additionally,
unique to RF lenses, this 28-70mm incorporates a configurable Control Ring for
intuitively adjusting exposure settings, including ISO, aperture, and exposure
compensation, from the lens itself. - Standard wide-angle to short-telephoto zoom lens is designed
for use with full-frame Canon RF-mount mirrorless cameras.
- Impressively bright f/2 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.
- Ultra-Low Dispersion (UD) elements are featured in the
optical design, and help to suppress color fringing and chromatic aberrations
in order to achieve greater clarity and color accuracy throughout the zoom
range.
- A ring-type Ultrasonic Motor (USM), along with an internal
focusing design, 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 nine-blade diaphragm contributes to a pleasing bokeh
quality.
