Just to add on: Aspherical or not aspherical? [Archive] - BirdForum

"As far as I know & remember, the Zeiss range does not feature aspherical lenses. What they do have is an objective lens system utilizing a special glass which helps bring different wawelengths (read: colours) of light closer to the same focus"
