Sigma 24mm f/1.4 DG HSM Art Lens for L-Mount

Sigma 24mm f/1.4 DG HSM Art Lens for L-Mount

The wide and fast Sigma 24mm f/1.4 DG HSM Art Lens for L-Mount is a highly regarded member of the ART line of Sigma's Global Vision Series and is characterized by its advanced optical construction and robust physical design.

The combination of three "F" Low Dispersion (FLD) elements and four Special Low Dispersion elements help to achieve a marked reduction in chromatic aberrations, while a pair of aspherical elements, with one positioned in the rear of the lens, minimize a variety of additional distortions and aberrations. The 15-element-in-11-group optical design is poised to deliver consistent peripheral brightness and sharpness, even when working at the bright f/1.4 maximum aperture. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and colour fidelity.

Offering best-in-class optical performance, this lens is designed to minimize sagittal coma flare, chromatic aberration, distortion, and vignetting to achieve exceptional levels of optical performance for images virtually free of streaking and warping. This lens provides the best possible performance when photographing a variety of subjects from cityscapes, mountain ranges, and the star-filled night sky to indoor photography with low illumination or scenes that require a smooth bokeh effect.

Complementing the optical performance is an equally adept Hyper Sonic Motor, which provides fast, smooth, and near-silent autofocus performance. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control. Additionally, nine rounded diaphragm blades contribute to pleasing out-of-focus quality when working with shallow depth of field techniques.

SIGMA expertise and leading-edge manufacturing technologies deliver breathtaking optical performance.

This lens features minimized aberration achieved through the latest design technology and know-how that has been accumulated by SIGMA in its lens development over many years and offers astonishing rendering performance, even at the edges, with ultra-high resolution.

Whilst featuring higher resolution around the focus point, this lens offers a smooth and natural bokeh effect. Both high definition rendering without chromatic aberration and natural bokeh expression are possible, even at maximum aperture.

Flare and ghosting reduction

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

Rounded diaphragm

When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect even at large-aperture settings.

Minimized sagittal coma flare for optimal capture of starry nightscapes.

Sagittal coma flare is the aberration in which a point light source appears as a streak instead of a point, and it affects large-diameter lenses in particular.

Sigma have adjusted the angle of incidence of light for optimal power distribution by positioning aspherical lens elements toward the rear of the lens

Even at wide-open aperture, you will enjoy outstanding image quality. Since streaking of point light sources toward the edges of the image is minimized, this lens is a powerful ally in photographing celestial bodies, nighttime illumination, and more.

Minimized chromatic aberrations - thanks to FLD and SLD glass lenses.

The 24mm F1.4 DG HSM | Art incorporates FLD ("F" Low Dispersion)* glass and SLD (Special Low Dispersion) glass elements to minimize chromatic aberration of magnification, which is mainly visible around the edge of the image. Moreover, the power distribution ensures the correction of axial chromatic aberration. The result is high image quality throughout the entire focusing range sharp and high-contrast image rendering without colour blur.

*FLD glass is ultra-low-dispersion glass that offers the performance of the highest level. Highly transparent, its refractive index and dispersion are extremely low as compared to conventional types of glass. It offers characteristics very similar to those of fluorite, which is valued for its anomalous dispersion. These characteristics minimize residual chromatic aberration (secondary spectrum), which cannot be corrected by the ordinary optical glass while helping to produce sharp, high-contrast images.

The finest in materials, usability and functionality.

All lenses in SIGMA's new Art line come with a hood with a high-quality rubberized connector and feature a newly designed lens cap and AF/MF switch. Inside, HSM (hypersonic motor) delivers high AF speed and extremely quiet performance. Full-time manual focus override is another key feature that leaves the artistic touches in the photographer's hands.

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

In both the external and internal parts, the optimized use of TSC (Thermally Stable Composite), further contributes to the high-precision construction of the lens.

HSM (Hyper Sonic Motor)

HSM (Hyper Sonic Motor) delivers high AF speed and extremely quiet performance. SIGMA's latest AF algorithm makes possible even smoother automatic focusing.

High-precision, rugged brass bayonet mount

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

TSC (Thermally Stable Composite)

The lens barrel of the new series of SIGMA lenses features a new TSC (Thermally Stable Composite)* that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens. *TSC (Thermally Stable Composite) offers thermal expansion characteristics similar to those of aluminium. Parts made with TSC deform less, making possible lens construction of extremely high precision.
