The Sony E-mount 24mm f/1.4 DG HSM Lens is a distinguished member of Sigma's esteemed Art line within the Global Vision Series. This lens is notable for its sophisticated optical design and sturdy construction. It incorporates three "F" Low Dispersion (FLD) elements alongside four Special Low Dispersion elements, significantly minimizing chromatic aberrations. Furthermore, the inclusion of two aspherical elements, one of which is located at the rear, effectively reduces various other distortions and aberrations. With a 15-element configuration arranged in 11 groups, this lens is engineered to maintain consistent peripheral brightness and sharpness, even at the maximum aperture of f/1.4. A Super Multi Coating has also been applied to the lens elements to mitigate flare and ghosting, thereby enhancing contrast and color accuracy.

In addition to its optical excellence, the lens features a highly efficient Hyper Sonic Motor that ensures rapid, smooth, and nearly silent autofocus operation. This motor allows for full-time manual focus override simply by rotating the focus ring, providing users with precise manual control. Moreover, the nine rounded diaphragm blades enhance the aesthetic quality of out-of-focus areas, making it ideal for shallow depth of field applications.

• Within the Art line of Sigma's Global Vision series, this lens is engineered to deliver exceptional optical performance, making it particularly suitable for creative and artistic endeavors.
  
  
• This prime wide-angle lens is tailored for full-frame Sony E-mount mirrorless cameras, but it is also compatible with APS-C models, providing a focal length equivalent to 36mm.
  
  
• The fast f/1.4 maximum aperture is advantageous for low-light photography and offers enhanced control over focus positioning when employing shallow depth of field techniques.
  
  
• Designed with a sophisticated optical configuration, this lens achieves high resolution and sharpness, ensuring consistent illumination from edge to edge. It features a pair of aspherical elements, including one positioned at the rear, which corrects for sagittal coma flare, distortion, and axial chromatic aberration, while allowing full utilization of the f/1.4 maximum aperture without compromising peripheral brightness and sharpness.
  
  
• Incorporating three FLD and four SLD glass elements, the lens effectively addresses chromatic aberrations across the entire focusing range, ensuring high image sharpness, clarity, and contrast, regardless of the focus point or aperture setting.
  
  
• A Super Multi-Layer Coating has been applied to the lens elements to reduce lens flare and ghosting, contributing to the production of contrast-rich and color-neutral images, even in challenging backlit situations.
  
  
• The integrated HSM (Hyper Sonic Motor) facilitates rapid and silent autofocusing, further enhanced by an optimized AF algorithm that ensures smooth focusing performance. Additionally, the HSM allows for full-time manual focus control by simply rotating the focus ring at any moment. A rounded nine-blade diaphragm contributes to creating a pleasing out-of-focus quality.
  
  
• A nine-blade diaphragm with a rounded design contributes to a pleasing bokeh effect.
  
  
• The lens is made from a Thermally Stable Composite (TSC) material combined with conventional metals, enhancing precision and performance across a wide range of temperatures. Additionally, the exterior of the lens barrel features an engraving indicating the year of manufacture.
  
  
• The bayonet mount is crafted from brass, ensuring both accuracy and longevity.
  
  
• The provided lens hood is equipped with a rubber connection, ensuring a secure attachment.
