Sigma 14mm f/1.8 Art DG HSM Lens for Sony E Mount

The Sigma 14mm f/1.8 DG HSM for Sony E-mount is a remarkable wide-angle prime lens that combines speed and breadth, specifically engineered to deliver high-resolution and well-corrected images. As a member of the Art series, this lens prioritizes image quality and rendering excellence, incorporating both FLD and SLD glass elements to effectively manage chromatic aberrations and color fringing, resulting in exceptional clarity. The inclusion of four aspherical elements, notably the large-diameter precision-molded glass element at the front, further minimizes distortion and spherical aberrations, enhancing sharpness and accuracy. Moreover, a Super Multi-Layer Coating has been applied to each element to reduce lens flare and ghosting, thereby improving contrast in challenging lighting conditions. This lens is particularly advantageous for astrophotography and low-light outdoor photography, offering a distinctive combination of a wide perspective and rapid, adaptable performance.

In addition to its optical capabilities, the lens features a highly efficient Hyper Sonic Motor that ensures fast, smooth, and nearly silent autofocus operation. This motor also allows for full-time manual focus override simply by rotating the focus ring, enabling precise manual control and the ability to focus as closely as 10.6 inches. The lens barrel is made from a Thermally Stable Composite material, which facilitates operation across a broad range of temperatures and conditions, while the brass lens mount ensures durability and precise mounting accuracy.

• As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
  
  
• Prime wide-angle lens is designed for full-frame Sony E-mount mirrorless cameras, however it can also be used with APS-C models where it will provide a 21mm equivalent focal length.
  
  
• Bright f/1.8 maximum aperture is well-suited for working in low and difficult lighting conditions.
  
  
• Three F Low Dispersion (FLD) and four Special Low Dispersion (SLD) elements are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.
  
  
• Four aspherical elements, including one large, 80mm-diameter precision-molded glass aspherical element, help to minimize distortion and spherical aberrations for improved sharpness.
  
  
• A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
  
  
• The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
  
  
• The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
  
  
• The bayonet mount is constructed from brass for ensured accuracy and durability.
