1. Sigma APO 300mm F2.8 EX DG HSM (Canon)
The Canon EF-mount Sigma APO 300mm f/2.8 EX DG HSM is a super-telephoto prime also characterized by its advanced optical and physical design. Its fast f/2.8 maximum aperture aids in isolating subjects using depth of field and also supports working in low-light conditions. A multi-layer coating has also been applied to lens elements to control flare and ghosting for improved contrast and clarity. The physical design also incorporates a removable, rotating tripod collar for easy attachment to a tripod or monopod, and a drop-in filter slot permits working with rear 46mm filters, such as the included circular polarizer filter. Super telephoto prime is designed for full-frame Canon EF-mount cameras, however can also be used with APS-C models where it provides a 480mm equivalent focal length. The multi-layer coating has been applied to individual elements to minimize flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions. A removable, rotating tripod collar offers well-balanced support for photographing atop a tripod or monopod with either vertical or horizontal shooting orientations.
2. Sigma 105mm F/1.4 DG HSM Art (Canon)
The Canon EF-mount 105mm f/1.4 DG HSM Art Lens from Sigma is a short-telephoto, portrait-length prime distinguished by its bright maximum aperture and advanced optical layout. The fast f/1.4 design greatly benefits working in low-light conditions and also affords extensive control over depth of field for isolating subjects and working with selective focus. As part of the Art line of lenses, this lens is also 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, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision. For working atop a tripod, a removable tripod collar is also included and features an Arca-type compatible foot for wide mounting compatibility. Short-telephoto prime, this 105mm f/1.4 lens is designed for full-frame Canon EF-mount DSLRs, however, can also be used with APS-C models where it provides a 168mm equivalent focal length. Three F Low Dispersion (FLD) and two 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. 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. Included rotating tripod collar features an Arca-type compatible foot for seamless use atop a tripod or monopod. This collar can also be removed from the lens, and a protective cover takes its place, for more comfortable handheld use. This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
3. Sigma 28mm F/1.4 DG HSM Art (Nikon)
The Nikon F-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 landscape photography. Impressively bright, the fast f/1.4 maximum aperture is ideal for working in low-light conditions and also offers greater control over depth of field for isolating subject matter. The advanced optical design is employed, which uses both low dispersion glass and aspherical elements to reduce chromatic and spherical aberrations for greater clarity and sharpness. A Super Multi-Layer Coating is also featured and suppresses ghosting and flare for improved contrast and color accuracy. 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 FX-format Nikon F-mount cameras, however, is also suitable for use with DX models where it provides a 42mm equivalent focal length. 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 bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant. This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
