Vario-Sonnar T* 24–70mm F2.8 ZA SSM SAL2470Z
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
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.

Distagon T* 24mm F2 ZA SSM SAL24F20Z
Representing the wide end of the A-mount Carl Zeiss prime lens range, the
24mm focal length of this model provides a wide perspective on 35mm
full-frame format cameras, and a closer-to-normal equivalent focal length

prime approach to general shooting will love this lens, as will those who
appreciate the subtle but tangible quality advantage that a first-class
prime provides. Use it indoors, on the street, or in the wild for images that
can bring your artistic vision to life. In addition to unimpeachable optical
