3. SIGMA 28MM F1.4 DG HSM ART

The Canon EF-mount Sigma 28mm f/1.4 DG HSM Art Lens is a versatile lens with a classic broad field of view that suits everything from street shooting to astrophotography. Impressively bright, the fast f/1.4 maximum aperture is ideal for working in low-light conditions and also offers greater control over the depth of field for isolating subject matter. An advanced optical design is employed, which uses both lowdispersion glass and aspherical elements to reduce chromatic and spherical aberrations for greater clarity and sharpness. The physical design features a brass bayonet mount, which offers rigidity and mounting precision along with a seal to guard against dust and moisture. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality. Wide-angle prime is designed for full-frame Canon EF-mount cameras, however, is also suitable for use with APS-C models where it provides a 44.8mm equivalent focal length. Two F Low Dispersion (FLD) and three 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. 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.

4. SIGMA 40MM F/1.4 DG HSM ART LENS

The Canon EF-mount Sigma 40mm f/1.4 DG HSM Art Lens is a wide normal-length lens characterized by a bright design and sophisticated optical layout. The fast 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 design incorporates a series of low dispersion and aspherical elements, which help to improve sharpness and clarity by controlling both spherical and chromatic aberrations. Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with a full-time manual focus override. The physical design features a brass bayonet mount, which offers rigidity and mounting precision along with a seal to guard against dust and moisture. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality. Short-normal prime is designed for full-frame Canon EF-mount cameras, however, is also suitable for APS-C models where it provides a 64mm equivalent focal length. Three F Low Dispersion (FLD) and three 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. 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.
