Canon's L-series FD fast wide — the New FD 24mm f/1.4L with an aspherical element.
The Canon New FD 24mm f/1.4L was introduced in 1979 as the New FD, L-series successor to Canon's fast 24mm wide-angle prime for the FD manual-focus system. As an L lens it used an aspherical element and sat at the top of the FD 24mm range as the professional fast wide of the New FD era.
This is a manual-focus Canon FD lens with a fixed 24mm focal length and a maximum aperture of f/1.4. It belongs to Canon's L series, incorporating an aspherical element to correct aberrations wide open, and carries the New FD black barrel with its redesigned bayonet. Focus and aperture are set manually on the lens.
The combination of a wide 24mm angle with an f/1.4 aperture provides strong low-light capability and control over depth of field for a wide focal length. It suits available-light reportage, interiors, environmental portraits and night photography where the photographer wants both breadth of view and speed.
On the used market the New FD 24mm f/1.4L is a sought-after L lens and commands a premium, so verify the aspherical optics carefully. Look for haze, fungus, coating marks and separation, confirm the aperture blades are oil-free and the rings move smoothly, and check the mount for wear. It is popular on mirrorless via an optics-free FD adapter.
