USED Canon RF10-20mm F4 L IS STM

Product Features

• Achieves ultra-wide-angle shooting with a focal length of 10mm, enabling expansive shots in confined spaces or buildings, and dynamic perspective expression for vast landscapes and celestial objects.
• Covers up to a focal length of 20mm, allowing for high-freedom photographic and video expression utilizing zoom not only for still images but also for video.
• Achieves high-quality depiction with minimal color bleeding by effectively arranging 16 elements in 12 groups, including one "Super UD Lens" and three "UD Lenses," correcting chromatic aberration across the entire zoom range.
• Employs special coatings "SWC (Subwavelength Structure Coating)" and "ASC (Air Sphere Coating)" to reduce the occurrence of flare and ghosting caused by internal lens reflections.
• Features an in-lens optical image stabilization mechanism providing a 5.0-stop image stabilization effect. When attached to an "EOS R3," it delivers a 6.0-stop image stabilization effect.
• Incorporates a dust- and moisture-resistant structure in the mount, control ring, focus ring, zoom ring, switch parts, and button parts.
• The front element is treated with a fluorine coating that repels oil and water droplets, ensuring ease of maintenance.
• Equipped with a "Lens Function Button" easily operated by the left thumb, allowing for switching to arbitrarily assigned functions such as AF or exposure while holding the camera.
• Achieves a constant maximum aperture of F4 across the entire 10mm to 20mm zoom range, enabling stable shooting with minimal exposure variation even during video zoom.
• For cameras equipped with in-body image stabilization, coordinated control with cameras featuring Movie Electronic IS suppresses camera shake even during handheld walking shots.
• Equipped with a lead-screw type stepping motor (STM) for smooth AF drive.
