Canon RF 800mm f11 IS STM Lens

Key Features

• Unparalleled 800mm Reach: Delivers extreme telephoto magnification, enabling photographers to capture tight, frame-filling images of distant wildlife, birds, and aircraft without disturbing the subject.
• Retractable and Compact Construction: Features a mechanical locking barrel that collapses down to just 281.8mm in length when stowed, allowing it to easily slide into standard camera bags.
• Ultralight Hand-Held Profile: Weighing only 1,260 grams, it stands as one of the lightest autofocus 800mm lenses ever built, eliminating the necessity of heavy tripods or monopods for field assignments.
• Gapless Dual-Layer Diffractive Optics (DO): Integrates advanced DO glass technology to effectively combat chromatic aberrations and color fringing while aggressively reducing the physical weight and size of the lens barrel.
• Up to 4 Stops of Optical Image Stabilization:

  Built-in optical IS counteracts camera shake by up to 4 stops, ensuring sharp stills and stable handheld video capture at massive focal distances.

• Fixed f/11 Architecture: Operates at a constant, non-adjustable f/11 aperture, optimizing the inner optical pathway for a highly streamlined body and daytime tracking.
• Lead Screw-Type Stepping Motor (STM): Employs a rapid, quiet, and smooth STM autofocus drive that links natively with on-sensor phase detection for dependable continuous subject and animal eye tracking.
• Tactile Configurable Control Ring: Features a physical control ring near the front element for intuitive, direct adjustments over exposure settings like ISO, shutter speed, or exposure compensation.
• Extender Compatibility: Natively supports the Canon RF 1.4x and RF 2x Extenders, expanding the optic into a staggering 1120mm f/16 or a massive 1600mm f/22 super-telephoto system while retaining autofocus functionality.
• Integrated Rigid Tripod Mount: Equipped with a built-in, low-profile tripod socket along the base of the lens barrel to provide robust stability when balancing the system on monopods or heads.
