Great low light performance and striking depth of field
The lens features a very fast maximum aperture of f/2.8, this enables the lens to transfer up to 2 times more light to the sensor than a conventional zoom lens, and enables the camera to capture sharp and blur free images, even in low/dim light. The large f/2.8 aperture also enables you to capture a shallow depth of field, which will enable you to isolate your subject from the background for visually striking images.
Great optical performance
The Sigma 19mm f/2.8 DN lens features a optical construction that includes 3 glass moulded aspherical elements, and a Super Multi-Layer Coating. The elements and coating effectively reduces chromatic aberrations, flares, and ghosting to provide sharp and artefact free images.
Fast and near silent internal autofocus system with manual override
The Sigma 19mm lens features a linear autofocus motor which moves the lens elements directly to deliver quick, accurate, smooth, and near silent focusing.
