Aurora 85mm f / 1.4 sony e-mount

Lens for precise and light portraits
Combining an impressive optical design to a compact and light form factor, the Sony E-mount lens Aurora 85 mm f / 1.4 of Sirui promises sharp images for photographic and video applications. Its bright maximum opening of f / 1.4 works together with a 15-sided diaphragm to produce a uniform and beautiful bokeh that not only completes the subject, but helps to make him stand out with respect to the background. To ensure better image quality and prevent ghost images, aspheric lenses are incorporated in the lens design, and HRI. The frontal element of the lens is protected by an antifouling coating to fluorine, which minimizes the possibility of dust and oil compromise it.
