A wide and fast Canon EF-mount prime, the 24mm f/1.4 DG HSM Lens is a member of the highly regarded Art line of Sigma's Global Vision Series and is characterized by its advanced optical construction and robust physical design. The combination of three "F" Low Dispersion (FLD) elements and four Special Low Dispersion elements help to achieve a marked reduction in chromatic aberrations, while a pair of aspherical elements, with one positioned in the rear of the lens, minimize a variety of additional distortions and aberrations. The 15-element-in-11-group optical design is poised to deliver consistent peripheral brightness and sharpness, even when working at the bright f/1.4 maximum aperture. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.

An optically advanced wide-angle prime, the Canon EF 35mm f/1.4 DG HSM Art Lens from Sigma mixes a comfortable focal length with an especially fast design. The bright f/1.4 maximum aperture helps to achieve shallow depth of field and selective focus effects, and also suits working in difficult lighting conditions. The optical layout incorporates both low dispersion and aspherical elements, which help to improve sharpness and clarity by controlling both spherical and chromatic aberrations. A floating elements system is also used to maintain performance throughout the focusing range. A Super Multi-Layer Coating is also featured, and helps to minimize flare and ghosting for greater contrast and color accuracy when working in strong lighting conditions.

The Canon EF mount Sigma 50mm f/1.4 DG HSM Lens is a fast standard-length prime designed to achieve high optical performance through the incorporation of both three Special Low Dispersion glass elements and one molded glass aspherical element. These elements, coupled with an advanced optical design, work to minimize sagittal coma flare and chromatic aberrations in order to provide high image sharpness and clarity. The lens' large diameter and floating system also help to correct for vignetting to ensure maintained peripheral brightness. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.

Sigma looked to create a peak portrait prime with the 85mm f/1.4 DG HSM Art Lens, and they delivered an optic with high performance, a large f/1.4 aperture, and a variety of technologies. Available here with a Canon EF mount, this lens offers a super-fast f/1.4 aperture that is great for getting images with an exceptionally shallow depth of field and smooth bokeh. It also uses two SLD elements, one anomalous partial dispersion/high-refractive index element, and one aspherical element that minimize aberrations and ensures a crisp, clear image. A Super Multi-Layer coating helps by suppressing flare and ghosting.

A fast telephoto prime, the Canon EF-mount 135mm f/1.8 DG HSM from Sigma pairs bright and sophisticated optics with intuitive handling and design. As part of the Art line of lenses, this 135mm f/1.8 is designed for high-resolution rendering, and utilizes FLD and SLD glass to control chromatic aberrations and color fringing for notable clarity. A Super Multi-Layer Coating also enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions. Additionally, making it an ideal lens for portraiture, the bright f/1.8 maximum aperture pairs with a rounded nine-blade diaphragm to benefit selective focus and shallow depth of field imaging with smooth bokeh.
