Sigma 90mm f/2.8 DG DN Contemporary Lens for Sony E

The Sigma 90mm f/2.8 DG DN Contemporary Lens designed for the Sony E-mount is a short-telephoto prime lens that delivers exceptional optical quality. It is particularly effective for portrait photography and selective everyday use, featuring a fast f/2.8 aperture that allows for precise depth of field control and performance in challenging lighting situations. This lens is equipped with an aspherical element along with five specialized low dispersion elements to minimize various aberrations, resulting in remarkable sharpness and clarity. Additionally, it includes a manual aperture ring for improved tactile feedback, and a stepping motor is integrated for swift and silent autofocus operation. The nine-blade rounded diaphragm contributes to aesthetically pleasing bokeh, while the all-metal construction of the lens is weather-sealed, making it suitable for use in adverse weather conditions.
