A constant f/4 aperture makes operation smooth and consistent throughout the zoom range. The lens further benefits from the use of one extra-low dispersion element and five aspherical elements to combat aberrations as well as a Zeiss anti-reflective coating to keep flare and ghosting to an absolute minimum.
