Canon RF 800mm f/11 IS STM Lens

The Canon RF 800mm f/11 IS STM is a unique super-telephoto prime lens designed for full-frame Canon RF-mount mirrorless digital cameras. Here are its key features:

Sleek and Portable Design:

The lens features a fixed f/11 aperture, contributing to its sleek and portable form factor. This design makes handheld super-telephoto shooting practical, allowing photographers to capture distant subjects with ease. Despite its powerful telephoto reach, the lens maintains a compact and lightweight profile, making it highly portable and suitable for various shooting situations.

Optical Design:

The lens employs gapless dual-layer diffractive optics, a specialized optical layout that effectively controls chromatic aberrations and spherical aberrations. This technology enables the lens to achieve high clarity and sharpness, ensuring excellent image quality even at extreme focal lengths.

Retractable/Extendable Design:

The lens features a retractable/extendable design with a locking lens barrel. This mechanism allows the lens to retract, reducing its size for easy storage and transportation. When extended, the lens is ready for shooting, providing an impressive super-telephoto reach.

Optical Image Stabilization:

The lens is equipped with an Optical Image Stabilizer (IS) that minimizes the appearance of camera shake by up to four stops. This feature enhances stability, especially in low-light conditions, allowing for sharper images at slower shutter speeds.

STM Stepping Motor:

The lens incorporates an STM (Stepping Motor) for autofocus. This motor delivers fast, quiet, smooth, and accurate autofocus performance, making it ideal for both still photography and video recording. The quiet operation is particularly advantageous for video shooters, ensuring minimal noise during focus adjustments.

Control Ring:

The lens features a configurable Control Ring that allows users to adjust various exposure settings, including aperture, ISO, and exposure compensation, directly from the lens. This intuitive control enhances the overall shooting experience, enabling quick adjustments without having to navigate camera menus.

Compatibility with Teleconverters:

The lens is compatible with optional Extender RF 1.4x and Extender RF 2x teleconverters. When used with these teleconverters, the lens’s effective focal length can be further increased, providing photographers with even greater reach. With the Extender RF 1.4x, the equivalent focal length becomes 1120mm, and with the Extender RF 2x, it reaches 1600mm.
