Key Features

• Ultra-Wide 10-20mm Focal Length

  • Expansive Field of View: The 10-20mm focal range provides an ultra-wide perspective, making it ideal for capturing vast landscapes, large architectural structures, and dynamic interior spaces. The lens allows photographers to fit more into the frame, creating a sense of space and depth in the images.
  • Creative Composition: The wide-angle nature of this lens offers opportunities for creative compositions, emphasizing foreground elements while maintaining sharpness across the frame.

• Constant f/4 Maximum Aperture

  • Consistent Exposure: The constant f/4 aperture ensures consistent exposure settings throughout the zoom range, making it easier to shoot in variable lighting conditions without adjusting the aperture.
  • Balanced Light Gathering: The f/4 aperture strikes a balance between light gathering and maintaining a compact, lightweight design, making it a versatile choice for a wide range of shooting scenarios.

• Advanced Optical Image Stabilization

  • Up to 4 Stops of Stabilization: The built-in Image Stabilization system compensates for camera shake, allowing for sharper handheld shots, especially in low light conditions or when shooting at slower shutter speeds.
  • Enhanced Stability for Video: The IS system also provides smoother footage for videographers, minimizing the effects of camera movement when recording handheld.

• High-Quality Optics

  • L-Series Construction: The lens features a sophisticated optical design with multiple aspherical elements and Ultra-Low Dispersion (UD) glass elements to minimize distortions, chromatic aberrations, and ghosting, ensuring sharp, high-contrast images with accurate color reproduction.
  • Air Sphere Coating (ASC): Canon's ASC technology further reduces flare and ghosting, particularly in backlit situations, providing greater clarity and contrast in challenging lighting conditions.

• Stepping Motor (STM) for Smooth Autofocus

  • Quiet and Fast AF: The lens is equipped with an STM, which delivers fast, smooth, and quiet autofocus performance. This is particularly beneficial for videography, where noise from the autofocus motor can be distracting.
  • Full-Time Manual Focus: The lens offers full-time manual focus override, allowing for precise adjustments even in autofocus mode, giving photographers and videographers greater control over their compositions.

Additional Benefits

• Professional-Grade Build Quality

  • Weather-Sealed Design: As part of the L-series, this lens is built to withstand the elements, featuring robust weather sealing that protects against dust and moisture, ensuring reliable performance in challenging outdoor environments.
  • Fluorine Coating: The front and rear elements are treated with a fluorine coating, making them resistant to smudges and easier to clean, maintaining the lens's optical clarity over time.

• Versatile Applications

  • Ideal for Landscapes and Architecture: The ultra-wide focal length is perfect for capturing breathtaking landscapes, dramatic architectural scenes, and expansive interiors, making this lens an essential tool for photographers who specialize in these genres.
  • Compact and Portable: Despite its advanced features and robust build, the lens remains relatively compact and lightweight, making it a convenient option for travel and on-location shoots.
