New "F1.4" joins SIGMA's Art line.
The highest optical performance in its class, perfect for a variety of subjects from cityscapes to the star-filled night sky.

SIGMA has a proven reputation for wide-angle lens design and manufacturing. Drawing on this experience and design know-how, refined through development of the SIGMA 35mm F1.4 DG HSM | Art and SIGMA 50mm F1.4 DG HSM | Art, we have successfully minimized sagittal coma flare, chromatic aberration, distortion and vignetting to achieve exceptional levels of optical performance with almost no aberration or distortion. This lens provides the best possible performance when photographing a variety of subjects from cityscapes, mountain ranges and the star-filled night sky that demands great rendering, to indoor photography with low illumination or scenes with a smooth bokeh effect. Enjoy the astonishing optical performance from the new "F1.4" series that has just joined the SIGMA's iconic Art line.

1. Art line delivers high-level artistic expression.

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.

2. Highest optical performance in its class.

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.

Excellent correction of sagittal coma flare

Generally it is ideal for a lens to have a high rendering performance from the maximum aperture throughout the entire image. For instance, sagittal coma flare, where the point light sources do not gather at one point and leaves a tail, is a typical flare that occurs especially with wide-angle lenses. The SIGMA 24mm F1.4 DG HSM | Art has an optimized power layout, positioning aspherical lens elements at the rear and adjusting the incidence angle of the light source, enabling high rendering performance even from the widest aperture. It is perfect for astronomical photography and shooting illuminations because of the reduced blur on the point light sources near the edge of the image.

Excellent correction of chromatic aberration

One of the elements required to achieve high rendering performance is the correction of chromatic aberration. Particularly, for axial chromatic aberration that is hard to correct even during image processing, the lens development stage was vital in ensuring minimized distortion. The SIGMA 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 layout ensures the correction of axial chromatic aberration. Without any color blur, it achieves high image quality throughout the entire focusing range, thus achieving sharp and high contrast image rendering.

* FLD glass is the highest level low dispersion glass available with extremely high light transmission. This optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. These characteristics give excellent correction for residual chromatic aberration (secondary spectrum) which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images.

Minimized distortion

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.

High peripheral brightness

For a lens with a large diameter, brightness in the peripheral areas tends to be consequently lower compared to the center. By improving the efficiency at large apertures and minimizing vignetting, it secures very good brightness. Without considering the lack of light even at the open aperture, it ensures high contrast images for indoor photography, astronomical photography and when photographing blue sky.

Designed to minimize flare and ghosting

3. Customization and flexible adjustment for convenience or a specific purpose is possible.

4. New product lines from SGV concepts that are setting new benchmarks for image quality.

Design Concept

With the new product lines, supplied hoods incorporate rubber for the connected part. Lens caps and AF/MF switches are also newly designed in order to improve usability. For the parts inside, metals and a new material called TSC (Thermally Stable Composite)*, which works well with metals, are located to achieve products with high accuracy. The lens barrel includes the year of release, engraved for users to recognize when the lens was released.

* TSC (Thermally Stable Composite) offers thermal expansion characteristics similar to those of aluminum. Parts made with TSC deform less, making possible lens construction of extremely high precision. As compared to polycarbonate containing 20% glass, a commonly used material, TSC offers approximately 70% higher elasticity. As compared to polycarbonate containing 30% glass, it offers 25% higher elasticity. (Comparison is between SIGMA-produced components.)

"Made in Japan"

All SIGMA's manufacturing - right down to molds and parts - with a few exceptions, are carried out under a single integrated production system, entirely in Japan. We are now one of the very few manufacturers whose products are solely "made in Japan". We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of SIGMA products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world, because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.
