The extremely precise Bokeh makes it possible, for example, to focus on the pupil of the model and to blur the eyelashes at the same time. In addition to this impressive bokeh, the focus range is extremely high-resolution. The Sigma 85mm F1.4 DG HSM type features 14 lens elements in 12 groups - a remarkable structure that provides the ultra-high resolution of the lens. Therefore, this lens is an excellent choice for full-frame DSLRs with a resolution of 50 megapixels and more. To create an 85mm F1.4 lens that delivers such excellence, Sigma used its latest innovations in design and materials. The result is the ultimate lens for portraits. This lens reduces chromatic aberrations to an absolute minimum, providing performance beyond anything known, including amazing resolution and a gorgeous bokeh. There are now full-frame DSLRs in the ultra-high megapixel range with a resolution of 50 or more megapixels, and nothing better reveals the performance potential of these cameras than the performance of the lens. The Sigma 85mm F1.4 DG HSM Art contains two elements made of SLD glass (Special Low Dispersion) and one element with anomalous partial dispersion and high refractive index. These properties contribute to a clear image across the entire image plane. In addition, the optical design minimizes sagittal coma, enabling superior image quality without any streaking - even with the aperture wide open.
