***This lens is fitted with a seamless lens gear for use with follow focus applications***Standard wide-angle lens is designed for full-frame Sony E-mount mirrorless cameras, however it can also be used with APS-C models where it will provide a 52.5mm equivalent focal length.Pairing an immensely versatile focal length with a bright maximum aperture, the Sony E-mount 35mm f/1.4 DG HSM Art Lens from Sigma is a wide-angle prime characterized by its advanced optical design. The combination of one F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) 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. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity. Additionally, the f/1.4 maximum aperture benefits working in low-light conditions and offers increased control over depth of field for isolating subject matter.
