The lightest in its class and the brightest in Sigma's 50mm prime lineup, the 50mm f/1.2 DG DN Art Lens for Leica L-mount cameras is a well-designed lens for everyday use. Driven by Sigma's dual HLA (High-response Linear Actuator) motors, this lens delivers quiet and high-speed performance. Simultaneously, this focusing system allows for a more compact design, helping make this lens lighter than its counterparts. This classic focal length paired with an extremely wide f/1.2 maximum aperture allows users to effortlessly capture a variety of subject matter. Also, there are physical function buttons and switches that improve the lens's overall ease of use as well as its reliability in the field. To reduce ghosting and improve contrast, a super multilayer coating is used on the glass elements.
Sporting a f/1.2 maximum aperture, this 50mm prime lens provides rich and beautiful bokeh. Not only is this a massive benefit for creating more artistic and flattering imagery, but it allows you the ability to capture detailed images in harsh lighting conditions.
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.
Constructed with convenience in mind, the 50mm f/1.2 is equipped with multiple functions to assist you while shooting. An AFL button is available for maintaining focus on a single distance. Certain camera models allow for customizing the AFL's function.
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.
