The SIGMA 50mm F1.2 DG DN | Art is a dream lens for every photographer or filmmaker who loves creamy bokeh and shallow depth of field. It offers very high image quality and doesn’t suffer from chromatic aberrations or a lack of contrast, even when used wide open at that large f/1.2 aperture. As far as image and build quality are concerned, it goes head-to-head with the best fast lenses from other brands. But it does so with a smaller size, a lighter weight and at a cost-effective price, making the lens more accessible. Autofocus is also quite snappy, focus breathing is low, and the aperture can be de-clicked, making it suitable for filming as well as photography.
