There are ultra-fast prime lenses, and there are ultra wide wide-angle prime lenses. However, the Sigma 16mm f/1.4 DC DN Contemporary is an ultra-fast AND ultra wide-angle lens – and it's down to a bargain price of just £349 for the Sony E-mount.
The cool £100 saving makes an already appealing lens even more irresistible, with its ultra-wide f/1.4 aperture that's perfect for working in low light or adding some elusive background blur to your environmental images.
The Sigma 16mm f/1.4 DC DN Contemporary is an APS-C lens for Sony E-mount cameras that offers an equivalent wide-angle 24mm field in 35mm terms.
This compact optic is designed to accommodate fast and accurate autofocus, both during stills and video shooting – the latter benefitting from a stepping motor for smooth focusing.
The lens' optical construction minimizes aberrations and ensures outstanding resolution both wide open and throughout the aperture range, with a pair of high-precision aspherical elements to reduce the onion ring bokeh effect that some aspherical elements produce.
