This lens's rounded 13-blade diaphragm is a first for Sigma and maintains a circular shape, helping create smooth and round bokeh even when stopped down.
The dust- and splash-resistant lens structure combined with the front lens element's water and oil-repellent coating create a durable overall lens that's reliable in the field.
The aperture ring is lockable and can be set to click/de-click depending on your preference.
