Canon - 800 mmf/11 - Super Telephoto Fixed Lens for Canon RF

Experience the power of distance with the Canon RF 800mm F11 IS STM, the first compact and lightweight 800mm super-telephoto lens in the RF lineup. Designed for Canon RF-mount cameras, this fixed focal-length lens delivers extraordinary reach without the bulk of traditional super-telephotos, making it an ideal companion for wildlife, bird, outdoor sports, and aviation photographers. Its combination of portability, fast autofocus, and integrated image stabilization opens up new creative possibilities, letting you frame distant subjects with precision while keeping your rig manageable for long shoots in the field.

• Ultra-long reach in a compact, lightweight body. The RF 800mm F11 IS STM packs an 800mm focal length into a remarkably compact footprint for an 800mm prime. This enables you to capture distant wildlife, birds in flight, or aircraft with dramatic compression and subject isolation—without the burden or bulk of heavier telephotos. Its balance-and-portability make it a practical choice for hikers, birders, and travel shooters who crave reach without sacrificing mobility.
• Built-in Image Stabilization (IS) that helps you shoot sharp, at-a-distance images. With up to 4 stops of IS performance, you can shoot handheld in daylight or moderate lighting with confidence. The stabilization system is designed to counter camera shake common to long focal lengths, helping you maintain sharpness during panning or when shooting in challenging outdoor conditions. When paired with newer Canon bodies, you can maximize stabilization to preserve detail in fleeting moments and distant subjects.
• Fast, quiet STM autofocus for wildlife and video-friendly performance. The STM autofocus motor delivers smooth, near-silent focusing suitable for wildlife subjects that may be sensitive to noise, as well as video capture where continuous, unobtrusive AF is an asset. The combination of a fixed f/11 aperture with a dependable AF drive helps you lock onto moving subjects efficiently, while maintaining subject tracking even when subjects are partly obscured by foliage or variable lighting.
• Fixed f/11 aperture tuned for field versatility and weight efficiency. As a fixed aperture lens, the RF 800mm F11 keeps size and weight down compared with brighter 800mm options. The f/11 design provides enough light for daylight sessions and is well-suited for sunny conditions, while the lens’ optical layout is optimized to deliver sharpness, contrast, and edge-to-edge performance across the frame. This makes it a practical choice for enthusiasts who want long reach without trading away portability.
• Designed for Canon RF systems with practical handling for on-the-go shooting. Built specifically for RF-mount cameras, this lens integrates smoothly with RF bodies, offering intuitive balance, reliable focus performance, and a compact aesthetic that suits field use. The ergonomic design supports quick composition in dynamic environments—whether you’re crouched in a field watching birds or tracking fast-moving aircraft at a runway—while maintaining a compact profile in your setup bag.

how to install Canon RF 800mm F/11 IS STM

• Prepare your camera: Turn off the camera and remove any caps from the camera body and lens. Ensure your hands are clean to avoid transferring dust to the lens mount.
• Remove lens caps and align marks: Align the lens’ mounting index on the lens with the corresponding mark on the camera body. This alignment helps ensure a smooth, secure attachment.
• Mount the lens: Gently insert and rotate the lens onto the camera mount until you hear or feel a click indicating a secure connection. Ensure the lens is attached firmly before use.
• Check IS and focus settings: If you plan to shoot handheld, enable Image Stabilization on the camera or lens as appropriate. Select an AF mode suitable for your subject—servo/continuous for moving subjects or single-shot for still subjects—and verify proper focus on your subject before composing.
• Attach a support system if needed: For long-distance shots, especially with a heavy setup, consider using a sturdy tripod or monopod and a suitable collar to balance the rig. This helps reduce fatigue and improves stability for extended shoots.
• Power and test: Turn on the camera, set your exposure parameters, and perform a quick test frame to confirm focus and exposure. Fine-tune as needed to suit lighting and subject distance.
