Sigma 12-24mm f/4.5-5.6 DG HSM II Lens is an ultra-wide-angle zoom lens for full-frame sensors. Although the zoom magnification is calculated to be only 2 times, the screen configuration is greatly changed even if the focal length is 1mm in the ultra-wide angle range.

In the maximum wide angle area of 12mm, the angle of view of 122° can cover a very wide area in one picture. The photo taken at this focal distance is advantageous in expressing sense of space because perspective is strong.
At the maximum telephoto side of the lens at 24mm focal length, the shortest shooting distance is 28cm, which is very close to the subject. If a close-up shot is taken at this angle, not only the subjects but also the environment can be contained inside the screen. A wide-angle lens is more likely to generate aberrations than a telephoto lens. Therefore, Sigma 12-24mm f/4.5-5.6 DG HSM II Lens
has 9 low dispersion lenses such as FLD and SLD.
