In general, fixed focal length (or prime) lenses are less susceptible to lens flare than zoom lenses. Other than having an inadequate lens hood at all focal lengths, more complicated zoom lenses often have to contain more lens elements. Zoom lenses therefore have more internal surfaces from which light can reflect.
