The lens incorporates a manual aperture ring for enhanced tactility, and also featured is a stepping motor for quick and quiet AF performance. A rounded nine-blade diaphragm lets you achieve a pleasingly smooth bokeh, and the lens's all-metal body is weather-sealed to suit working in inclement conditions.
The SIGMA 90mm F2.8 DG DN | Contemporary for Sony E-Mount boasts exceptional optical performance with ultra-high resolving power to match the latest high-resolution mirrorless cameras.

Photographers can enjoy shooting with soft, large bokeh without coloration and this is something that only a full-frame lens is able to deliver. With a minimum focusing distance of 50cm and a maximum magnification ratio of 1:5, close-up macro-style photography is possible. The lens highlights the subject, allowing photographers to focus in on fine details or create more abstract compositions.
