A high-performance lens with a fast aperture and versatile focal range, the Sigma Art series lens is designed to deliver exceptional optical quality for creative and artistic applications. With a constant f/2.8 maximum aperture, it excels in low-light conditions and provides precise depth-of-field control for shallow depth-of-field techniques.
This autofocus lens is compatible with full-frame Sony E-mount mirrorless cameras, while also offering compatibility with APS-C models, providing a focal length range equivalent to 36-105mm. The integrated stepping motor ensures quick and silent autofocus, enhanced by an optimized AF algorithm for smoother focusing performance.
The lens incorporates a sophisticated optical design, including six F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements that effectively reduce chromatic aberrations and color fringing throughout the zoom range. Three aspherical elements control spherical aberrations and distortion, resulting in increased sharpness and accurate rendering. The application of Super Multi-Layer and Nano Porous Coatings to the lens elements minimizes lens flare, ghosting, and contributes to producing contrast-rich and color-neutral images, even in challenging backlit conditions.
When shooting at the wide-angle end, the lens allows for a minimum focusing distance of 7.1″ with a maximum magnification of 1:2.9, making it suitable for close-up subjects. At the telephoto end, the minimum focusing distance is 1.25′ with a maximum magnification of 1:4.5. The rounded 11-blade diaphragm contributes to a pleasing bokeh quality, adding to the aesthetic appeal of the out-of-focus areas.
The lens is equipped with several useful features, including an integrated AF-L button that can be customized for adjusting shooting settings. It also includes a dedicated AF/MF switch and a zoom lock switch to prevent accidental barrel extension.
Constructed with durability in mind, the lens features a chrome-plated brass bayonet lens mount for improved mounting accuracy and rigidity. Rubber seals are incorporated in the mount design, making it dust- and splash-resistant, allowing for shooting in harsh environments.
In summary, the Sigma lens combines exceptional optical performance, a fast aperture, versatile focal range, and durable construction, making it an excellent choice for photographers seeking high-quality results in various shooting conditions.
