Super long reach, super compact
design, the Canon RF 800mm f/11 IS STM is a unique telephoto
prime featuring a distinct mixture of focal length and form factor.
Characterized by its retractable design and a fixed f/11 aperture, this lens's
sleek profile makes handheld super-tele shooting a very real possibility, and
four stop-effective optical image stabilization further helps to achieve sharp
imagery when working in difficult lighting conditions. Also contributing to the
reduced size is a distinct optical layout, which uses gapless dual-layer
diffractive optics instead of multiple heavier individual elements, which also
effectively controls color fringing and chromatic aberrations for high clarity.
Complementing this design is an STM stepping motor that delivers quick and
quiet autofocus performance that is suitable for both stills and video needs.
Additionally, a Control Ring is also integrated into the lens design for
intuitive control over exposure settings from the lens itself. If you decide
you need more than 800mm, this lens is compatible with the 1.4x and 2x RF
Extenders for an equivalent focal length of 1120mm or 1600mm, respectively.
Super-telephoto prime is designed
for use with full-frame Canon RF-mount mirrorless digital cameras.
Fixed f/11 aperture contributes to
the sleek and portable form factor as well as a balanced mixture of depth of
field and sharpness.
Gapless dual-layer diffractive
optics contribute to a marked reduction in chromatic and spherical aberrations
as well as benefit the design of a relatively compact and lightweight lens.
Retractable/extendable design,
with a locking lens barrel, offers an impressively compact form factor
considering the super-telephoto design.
An Optical Image Stabilizer helps
to minimize the appearance of camera shake by up to four stops to better enable
working in low-light conditions and with slower shutter speeds.
STM stepping motor offers fast,
quiet, smooth, and accurate autofocus performance that is ideal for video
recording as well as still shooting.
Configurable Control Ring can be
used to adjust a variety of exposure settings, including aperture, ISO, and
exposure compensation.
Compatible with optional Extender
RF 1.4x and Extender RF 2x teleconverters to further increase the effective
focal length.
