Sigma 24mm F1.4 DG DN | A Lens - L Mount

The full-frame SIGMA 24mm F1.4 DG DN | Art is a high-performance, wide-angle prime for mirrorless systems.

It boasts a very wide F1.4 aperture, making it particularly well-suited to astrophotography as well as a wide range of photo or video applications where a wide angle-of-view and a fast aperture are beneficial.

The lens weighs in at 520g, making it about 30% lighter than Sigma’s existing 24mm F1.4, but it stills gains a range of important new features, including a manual aperture ring with de-click and lock functionality, a front filter thread and rear filter holder, and an all-new ManualFocus Lock (MFL) switch to fully deactivate the focus ring.

Optically the lens produces very sharp results at all apertures with well-suppressed optical aberrations such as sagittal coma flare.

This combination of superb image quality, excellent portability and an advanced feature-set, all built into a beautifully constructed body, make this versatile optic well-suited to both professional imaging and casual everyday shooting.

The superb optical performance of the SIGMA 24mm F1.4 DG DN | Art is powered by the optimal arrangement of its 17 elements, including two FLD, one SLD and four aspherical elements.

The suppression of a range of optical aberrations such as sagittal coma flare, which cannot be corrected in post, contribute to the lens’s ability to accurately reproduce bright points of light even in the extreme periphery of the frame.

At 520g it is 30% lighter than Sigma’s existing 24mm F1.4, and about 16% shorter.

This reduction in size and weight is thanks to design changes that have allowed more efficient positioning of internal parts, the development of more complex aspherical elements, and the freedom afforded by the short flange back distance.

Considering the wide angle-of-view, bright maximum aperture and high optical performance offered by the 24mm F1.4 DG DN, it is a remarkably portable option that is easily small enough for everyday use.

The robust body is built from a combination of aluminium and Thermally Stable Composite (TSC), giving it a sleek finish, and the focus ring has a smooth, well damped action.

A petal-shaped lens hood is included, and equipped with a lock mechanism to keep it securely fastened to the lens. A rubber grip makes it easier to attach and remove the hood.

The SIGMA 24mm F1.4 DG DN | Art is equipped with a range of features that make it easier to achieve professional-looking results.

The lens boasts both a front filter thread and a rear filter holder, which ensures plenty of attachment options.

Astrophotographers, for example, may want to attach a light pollution filter at the front and a soft filter at the rear.
