Sigma 24mm f/1.4 DG HSM Art Lens Canon EF
The flagship wide angle Sigma 24mm Art lens in Canon EF-mount delivers exceptional images for a wide range of subjects thanks to FLD & SLD glass elements to reduce distortion and chromatic aberration.
Sigma 24mm F1.4 DG HSM Lens - Canon Fit
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.
Leveraging optical expertise, Sigma has minimised sagittal coma flare for optimal capture of starry night scapes.
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. By positioning aspherical lens elements toward the rear of the 24mm f/1.4 DG HSM Art, we have adjusted the angle of incidence of light for optimal power distribution. Even at wide-open aperture, you will enjoy outstanding image quality. Since streaking of point light sources toward the edges of the image is minimised, this lens is a powerful ally in photographing celestial bodies, night time
Minimised chromatic aberrations—thanks to FLD and SLD glass lenses.

One of the requirements of high rendering performance is the correction of chromatic aberration. Particularly, for axial chromatic aberration, which is challenging to correct even during image processing, the lens development stage is vital in ensuring minimised distortion. The 24mm f/1.4 DG HSM Art incorporates FLD (“F” Low Dispersion)* glass and SLD (Special Low Dispersion) glass elements to minimise 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 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 minimise residual chromatic aberration (secondary spectrum), which cannot be corrected by ordinary optical glass, while helping to produce sharp, high-contrast images.
High-contrast images with bright edges—even at wide-open aperture.
Improving efficiency at large apertures and minimising vignetting, we have designed the lens to secure very good brightness. Even at open aperture, it ensures high-contrast images for indoor photography, astronomical photography, and when photographing blue sky.
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.
Exclusive low-dispersion glass
The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colours of light to focus at slightly different points. The result is chromatic aberration, the colour fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimise this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimisation of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.
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 is vital in ensuring minimised distortion. The SIGMA 24mm f/1.4 DG HSM Art features an adjusted incidence angle of the light source from the surface of the first lens and aspherical glass elements to optimise the power layout at respective positions. This has helped minimise distortion throughout the entire image.
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.
High-precision, rugged brass bayonet mount
