Description — Canon 50-300mm f/4.5 L
The Canon FD 50-300mm f/4.5 L is a manual focus, full-frame telephoto zoom lens built around the Canon FD mount. Its focal length range runs from 50mm to 300mm, giving shooters the flexibility to move between standard and long telephoto perspectives without changing lenses. A standout characteristic is its constant f/4.5 maximum aperture, which holds steady across the entire zoom range and simplifies exposure management in the field.
The lens weighs 1500g, reflecting its robust, professional-grade construction consistent with Canon's L-series lineup. A 72mm filter thread allows for the use of a wide variety of photographic filters. With no image stabilization and strictly manual focus operation, this lens rewards patient, deliberate shooters — particularly those using it on a tripod for wildlife, sports, or other telephoto applications.
It is a compelling option for photographers looking to work with vintage FD glass on adapted camera systems.
