Canon RF 800mm F11 is STM Lens - Super telephoto Lens Ideal for Wildlife and Travel. This is a great lens.
The Canon RF 800mm F11 IS STM Lens is a marvel of modern optical engineering, designed for photographers who need extreme telephoto reach in a compact and lightweight package. This lens is part of Canon's RF series, which is specifically designed for their mirrorless camera systems, ensuring seamless integration and optimal performance.
Design and Build
The lens features a sleek, matte black finish with a robust build quality that feels solid in hand. Despite its impressive focal length, the lens is surprisingly lightweight, weighing in at approximately 1260 grams (2.78 pounds). This is achieved through the use of advanced materials and a fixed aperture design, which eliminates the need for heavy glass elements. The lens measures about 281.8mm (11.1 inches) in length when retracted, making it relatively portable for an 800mm lens.
Optical Performance
The Canon RF 800mm F11 IS STM Lens boasts a fixed aperture of F11, which might seem unconventional, but it allows for a more compact and lightweight design. The lens construction includes 11 elements in 8 groups, featuring a combination of Super Spectra Coating (SSC) and Air Sphere Coating (ASC) to minimize ghosting and flare, ensuring high-contrast and sharp images even in challenging lighting conditions.
Image Stabilization
One of the standout features of this lens is its built-in Optical Image Stabilization (IS), which provides up to 4 stops of shake correction. This is particularly beneficial for handheld shooting at such extreme focal lengths, helping to produce sharp images even in low light or when using slower shutter speeds.
Autofocus System
The lens is equipped with a Stepping Motor (STM) for smooth and quiet autofocus performance. This makes it an excellent choice for both still photography and video recording, as the STM motor ensures minimal noise and precise focusing. The autofocus system is also compatible with Canon's Dual Pixel CMOS AF, providing fast and accurate focusing across the frame.
Handling and Features
The Canon RF 800mm F11 IS STM Lens includes a customizable control ring near the front of the lens barrel, allowing photographers to adjust settings such as aperture, ISO, or exposure compensation without taking their eyes off the subject. The lens also features a retractable design, which helps to reduce its size for easier storage and transport.
Compatibility
This lens is designed for use with Canon's RF-mount mirrorless cameras, such as the EOS R, EOS RP, EOS R5, and EOS R6. It can also be used with Canon's RF extenders, such as the RF 1.4x and RF 2x, to achieve even greater focal lengths, making it a versatile tool for wildlife, sports, and astrophotography.
Conclusion
In summary, the Canon RF 800mm F11 IS STM Lens is a unique and innovative telephoto lens that offers exceptional reach in a compact and lightweight form factor. Its fixed F11 aperture, advanced optical coatings, built-in image stabilization, and quiet autofocus system make it a practical choice for photographers who need to capture distant subjects with clarity and precision. Whether you're shooting wildlife, sports, or distant landscapes, this lens provides the performance and versatility needed to get the shot.
