This is another "catalog" lens from Sears, appearing very similar to the previous Sears 135mm but with a key difference: this version is built for the Canon FD system. It is a fast telephoto prime lens with a maximum aperture of f/2.8, making it excellent for low-light photography and achieving a soft, blurred background. It features "Multi Coated" optics (Image DSC_0000-1770) and a dedicated Macro range for closer focusing than a standard telephoto lens typically allows.
