Canon RF 800mm f/11 IS STM Review With Sample Photos

Canon released two unique lenses with the Canon RF 800mm f/11 IS STM and RF 600mm f/11 IS STM. Here is a RF 800mm f/11 IS STM review.

Christopher Frost Photography posted their Canon RF 800mm f/11 IS STM review.

At a glance:

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.
