The Canon RF 800mm F11 IS STM lens is a specialized super telephoto lens designed for Canon’s RF mount, offering exceptional reach and versatility for wildlife, sports, and distant subject photography.

Overview

The RF 800mm F11 IS STM combines a long focal length with a compact and lightweight design, making it highly portable compared to traditional super telephoto lenses. It’s well-suited for photographers looking to capture distant subjects without the bulk typically associated with such focal lengths.

Optical Features

Super Telephoto Reach:
With an equivalent focal length of 800mm on full-frame cameras, this lens provides an angle of view of approximately 2°35′ horizontally, 1°40′ vertically, and 3°05′ diagonally. This focal length is ideal for bringing far-away subjects close to the camera.

Image Stabilization (IS):
Equipped with Canon’s Optical Image Stabilizer (OIS) technology, the lens compensates for up to 4 stops of camera shake, allowing for sharper images handheld. This feature is invaluable in low-light conditions or when shooting at slow shutter speeds.

Autofocus and Motor

STM Motor:
The STM (Stepping Motor) autofocus system ensures fast and quiet focusing performance, making it suitable for both still photography and video recording. The smooth focusing operation is particularly beneficial for maintaining focus on moving subjects without disturbing nearby wildlife.

Compact and Portable Design

Measuring 101.6mm in diameter and 281.8mm in length when fully extended, and weighing just 1260g, the RF 800mm F11 IS STM is remarkably compact for its focal length. This design factor enhances mobility and ease of handling during prolonged shooting sessions in the field.

Lens Control Ring

Direct Control:
The lens features a customizable Control Ring that allows direct adjustments to key camera settings such as Tv (Shutter Speed), Exposure Compensation, and ISO sensitivity. This intuitive control enhances operational efficiency and flexibility while shooting.

Expandable Focal Length:
The RF 800mm F11 IS STM lens is compatible with Canon RF extenders, which extend its focal length to 1120mm with a 1.4x extender and up to 1600mm with a 2x extender. This versatility allows photographers to adapt to different shooting scenarios without compromising autofocus performance or image quality.
