With a no-holds-barred approach to design, the Sigma 105mm f1.4 DG HSM Art Sony E Fit Lens 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 utilises FLD and SLD glass to control chromatic aberrations and colour fringing for notable clarity. A Super Multi-Layer Coating also enhances image quality by suppressing lens flare and ghosting for improved contrast and colour fidelity in strong lighting conditions. Additionally, a rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
