Description — Canon FD 20mm f/2.8
The Canon FD 20mm f/2.8 is a prime, manual focus wide-angle lens built around the Canon FD mount for full-frame SLR cameras. Its 20mm focal length places it firmly in wide-angle territory, making it a natural choice for photographers working in expansive environments. The f/2.8 maximum aperture provides a useful light-gathering advantage for a wide-angle prime, offering flexibility across different lighting scenarios.
At 320g, the lens is easy to carry without adding excessive weight to your kit. The 72mm filter thread ensures compatibility with a broad range of standard filter systems, which is particularly practical for landscape and architectural photographers who frequently use ND or polarizing filters. Focus is entirely manual, requiring the photographer to set focus by hand — a workflow favored by many who want full control over their focus plane.
The lens carries no image stabilization, so steady technique or support is recommended at longer exposures.
