58mm · f/1.2
The Canon FL 58mm f/1.2 (II) is a vintage lens with a thorium element that can cause yellowing (trogdon). Optically, it shows more aberrations and is less sharp than the 55mm version (justruss), but offers more interesting bokeh (LightShow). Build quality is typical of the era, and sample variation may be significant (justruss). It suits users seeking a cheap, characterful fast lens for wide-open use, especially if they value bokeh over peak sharpness.
