If you insist on prime-lens image quality but envy the convenience of
variable focal length, here's a lens that brings the best of both worlds
together. For many discriminating photographers it is a lens that will
stay on the camera most of the time. Its versatile 24mm to 70mm zoom
range covers a wide gamut of shooting situations, and its extraordinary
sharpness and contrast are fully retained at all focal lengths and
20
apertures. Whether you're shooting a tight indoor scene at 24mm, a
portrait at 70mm, or anything in between, you'll feel and see legendary
Carl Zeiss quality in every shot.
