Canon FD 17mm f/4 - Canon FD Mount

The Canon FD 17mm f/4 is a vintage ultra-wide-angle prime lens designed for Canon’s manual focus SLR system. It provides a dramatic 104-degree diagonal angle of view with relatively low distortion for its era. The lens features a floating element system to maintain sharpness at close focusing distances. It is a popular choice for landscape photography and for adapting to modern mirrorless cameras due to its mechanical aperture control. Inspect the front element carefully for scratches, as the bulbous glass is prone to contact. The breech-lock or New FD mount should engage securely without play. Internal haze and fungus are common in lenses of this age, so a clear optic is essential. SDS checks the aperture blades for oil and ensures the manual focus ring operates smoothly across the entire range without dry spots in the lubrication.
