Sigma 24mm F1.4 DG HSM Art Lens

Sigma 24mm F1.4 DG HSM Art

The much anticipated 24mm F1.4 Art wide angle lens is designed for full-frame DSLRs, and when used on digital cameras with an APS-C size image sensor, it effectively becomes a 38mm. The lens is ideal for capturing a variety of photography subjects, including cityscapes, mountain ranges, astrophotography and weddings and is great for videography work as well.

SIGMA is organizing all its interchangeable lenses into three product lines; Contemporary, Art, and Sports, where each line has a distinctive concept. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression. With the astonishing rendering performance that meets the high standard, along with landscapes, portraits still-life, close-up, and casual snaps, they are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture and starry skies and many other scenes.

By minimizing aberration using the latest design technology and know-how that has been accumulated from lens development over many years, this lens achieves astonishing rendering performance, even in the corners, with ultra-high resolution. Whilst featuring higher resolution around the focus point, the lens ensures a smooth and natural bokeh effect. Both high definition rendering without color aberration and natural bokeh expression are possible, even from the maximum aperture.

Flare and ghosting were thoroughly measured and monitored from the lens development stage to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.

This lens incorporates a brass made bayonet mount which has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term use.

The 24mm also excels at indoor photography in low illumination thanks to the combination of exceptional focal plane sharpness, and gorgeous bokeh rendered by nine rounded aperture blades. The lens achieves a maximum magnification of 1:5.3 with a minimum focusing distance of 9.8 inches.

The 24mm incorporates both “F” Low Dispersion (FLD) glass and Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups to minimize chromatic aberration of magnification especially in the edge of the image field. Moreover, the optimized power layout includes aspherical elements that are positioned in the rear of the lens for improved wide open performance.

It is not possible to compensate for distortion that is often observed with wide-angle lenses just by changing the aperture value. Therefore, the lens development stage was vital in ensuring minimized distortion. The SIGMA 24mm F1.4 DG HSM | Art adjusted the incidence angle of the light source from the surface of the first lens and positioned each aspherical glass element to optimize the power layout at respective positions. This has helped it succeed in minimizing distortion throughout the entire image. This helps to ensure minimal distortion through the correction of axial chromatic aberration and sagittal coma flare. The new lens element design also delivers excellent peripheral brightness.

“The Sigma Art lenses are recognized by photographers for world-class performance, and the new 24mm F1.4 DG HSM will be a significant contribution to our selection of fast aperture prime lenses which is quickly becoming a strong force in the industry” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Sigma is redefining the expectations of fast-aperture full-frame prime lens performance, especially wide-open, and the results the 24mm F1.4 will deliver will be up to the exacting standards set by the 35mm F1.4 DG HSM and 50mm F1.4 DG HSM .”

The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function.

By optimizing the AF algorithm, smoother AF is achieved. It incorporates a new full-time manual focusing mechanism that switches to manual focusing, simply by rotating the focus ring, even when AF is being used. This allows the photographer to make focus adjustments quickly and easily.

With the optional SIGMA USB DOCK, you can also set it to conventional full-time manual focus override.

Other updates to this lens include a new full-time manual focusing mechanism that switches to manual focusing, simply by rotating the focus ring, even when AF is being used, first introduced on the 50mm Art. This allows the photographer to make focus adjustments quickly and easily. As with all new lenses under the Global Vision categories, every 24mm will be tested using Sigma’s own MTF measuring system, “A1,” in the company’s factory in Japan.
