Canon RF800/11 is STM(N) (International Version) — Compact 800mm f/11 Super-Telephoto

The Canon RF800/11 is STM(N) (International Version) delivers an 800mm super-telephoto reach in a remarkably compact, lightweight design—Canon’s first 800mm RF lens engineered for better portability. It features an Extending / Retracting Locking Lens Barrel Design that reduces its transport length and locks securely for use. Optical performance is boosted by Gapless double-layer Diffractive Optics (DO) to minimize chromatic aberration and preserve image quality. The lens is optimized around a fixed f/11 Aperture to maintain high resolution and contrast across the frame. For steadier handheld and telephoto shooting, it incorporates Optical Image Stabilization with up to 4 Stops* of Shake Correction.
