Canon 300mm F2.8 L is II USM EF Lens

The Canon EF 300mm f/2.8 IS II USM is a professional-grade super telephoto lens that builds upon its predecessor with enhanced performance and portability, now weighing approximately 13% less. Designed for speed and precision, it features improved image stabilization—including a third mode that activates only upon full shutter press—offering up to four stops of shake correction for optimal panning and action shots. Its advanced optical construction includes Fluorite elements to reduce chromatic aberration and a suite of coatings that minimize flare and ghosting. A newly developed Fluorine coating helps resist smudges, dirt, and fingerprints, ensuring reliable performance in demanding conditions. With an inner focusing system driven by a ring-type USM motor, a close focusing distance of 2.0 meters, and a compact form factor, this lens is engineered for professional use. It also includes a drop-in 52mm rear filter slot and a new security lock slot for added protection in the field.
