Description — Sigma 10-18mm f/2.8 DC DN
The Sigma 10-18mm f/2.8 DC DN Contemporary in L-Mount is an ultra-wide-angle zoom designed specifically for APS-C mirrorless camera systems. Its focal length range of 10mm to 18mm makes it well-suited for wide environmental shots, architecture, and any scenario where breadth of view is essential. The constant f/2.8 maximum aperture is maintained across the entire zoom range, providing consistent exposure control without needing to adjust settings as you zoom.
At just 260g, this lens is one of the more portable wide-angle zoom options available for mirrorless shooters, and the 67mm filter thread ensures compatibility with a broad selection of standard filter accessories. Both autofocus and manual focus are supported, offering adaptability across different shooting conditions. Note that the lens has no image stabilization, so handheld shooting in challenging light will depend on technique or in-body stabilization from the camera body itself.
