Sigma 24mm f1.4 DG HSM Art for Canon EOS

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.

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, the 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.

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 colour 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 colour blur, it achieves high image quality throughout the entire focusing range, thus achieving sharp and high contrast image rendering.

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 centre. 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 - 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 backligh
