The 105mm f/1.4 DG HSM Art Lens with Sony E-mount from Sigma is a short telephoto portrait lens with high aperture and advanced optical design. The f/1.4 aperture design greatly benefits low-light work, and also allows extensive control over depth of field for subject isolation and selective focus work. As part of the Art lens range, this lens is also designed for high-resolution rendering and uses FLD and SLD glass to control chromatic aberration and colour fringing for maximum clarity. Image quality is also enhanced by Super Multi-Layer Coating, which suppresses flare and ghosting on the lens and improves contrast and color fidelity under strong lighting. In addition, the rounded nine-layer aperture contributes to pleasing background blur.
The lens features a hypersonic motor that provides fast, smooth and quiet autofocusing with full manual focus control. The physical construction uses a thermally stable composite material to ensure durability in a variety of environments, and the brass bayonet offers rigidity and maximum precision when mounted on the camera body. A detachable tripod mount with a compatible Arca foot is also included for tripod work.
- Part of the Art Series within Sigma's Global Vision lineup, this lens is designed to deliver truly remarkable optical performance and is ideal for creative and artistic applications.
- This short telephoto lens with a base focal length of 105mm f/1.4 is designed for full-frame cameras, but can also be used with APS-C models, where it will provide an equivalent focal length of 157.5mm.
- The extremely luminous f/1.4 maximum aperture is suitable for low-light work and also provides better control over the plane of focus when shooting with shallow depth of field.
- Three low dispersion (FLD) F elements and two special low dispersion (SLD) elements are part of an optical design that helps reduce color dispersion and chromatic aberration to improve clarity and color accuracy.
- A single aspherical element helps reduce distortion and spherical aberration, and also contributes to greater overall sharpness and accurate rendering.
- The large 105mm front end contributes to better peripheral illumination, which also reduces vignetting.
- A Super Multi-Layer Coating has been applied to the lens elements to minimize flare and ghosting on the lens, helping to produce contrasting and color-neutral images even in backlight.
- The nine-blade lens contributes to a smooth and pleasing background blur.
- The integrated HSM (Hyper Sonic Motor) ensures fast and silent autofocusing, which is further complemented by an optimized autofocusing algorithm that ensures smoother focusing. The HSM also allows full manual control of focusing by simply rotating the focus ring at any time.
- The lens is made of thermally stable composite material (TSC) along with traditional metals for greater precision and use in large temperature differences.
- The lens mount is made of brass to ensure accuracy and durability. In addition, a rubber gasket is built into the design of the mount to resist dust and splash water.
- A protective coating has been applied to the front element to repel water and oil and facilitate cleaning.
- The included swivel tripod ring features an Arca-compatible foot for seamless use on a tripod or monopod. This housing can also be removed from the lens and a protective cap can be fitted in its place for more comfortable handheld use.
- The lens body is made from carbon fibre reinforced plastic to keep it both lightweight and extremely durable.
