Canon RF 135mm f1.8 L IS USM Lens

• Ultra-Bright f/1.8 Aperture: Offers incredible light-gathering capability and an extremely shallow depth of field, rendering busy backgrounds into smooth blur while keeping subjects perfectly sharp.
• Up to 5.5 Stops of Optical Image Stabilization: Features built-in optical IS that counteracts camera shake by up to 5.5 stops, expanding to a massive 8 stops of coordinated stabilization when paired with EOS R bodies that feature In-Body Image Stabilization (IBIS).
• High-Speed Nano USM Autofocus: Driven by a fast, near-silent, and incredibly precise Nano USM motor that excels at tracking fast-moving subjects like athletes, dancers, and wedding guests.
• Elite L-Series Optical Formula: Utilizes 17 elements in 12 groups, including three Ultra-Low Dispersion (UD) elements to completely eliminate chromatic aberrations and color fringing.
• Air Sphere Coating (ASC) & Super Spectra Coating: Combines advanced multi-layered anti-reflective coatings to minimize lens flare and ghosting, maintaining rich color and deep contrast under harsh lighting conditions.
• 9-Blade Circular Aperture: Delivers incredibly smooth, creamy background bokeh and perfectly rounded out-of-focus highlights for high-end fashion and portrait work.
• Integrated Customizable Control Ring: Features a dedicated physical lens ring on the barrel for tactile adjustment of core exposure settings such as aperture, ISO, shutter speed, or exposure compensation.
• Two Lens Function (L-Fn) Buttons: Equipped with dual programmable shortcut buttons on the top and side of the barrel, allowing quick access to focus hold, depth-of-field preview, or AF tracking presets.
• 0.7m Minimum Focusing Distance: Offers a short close-up focus capability with a maximum magnification of 0.26x, expanding creative framing options for tight headshots and close detail captures.
• Professional Weather-Sealed Chassis: Built to endure the rigors of field assignments with extensive dust- and moisture-resistant sealing throughout the outer lens barrel.
• Fluorine Protective Coating: Applied to the front and rear outer lens elements to repel water, oil, and fingerprints, making the heavy glass elements incredibly easy to clean.
