Sigma Art 35mm f/1.4 DG Lens for Sony is a high-quality lens with a maximum aperture of f/1.4. It is compatible with Sony E-mount cameras and offers auto and manual focus options. This lens is part of Sigma's Art series and has a focal length of 35mm. It also has a compatible filter size of 67mm and uses a 67mm lens front. This lens is used and therefore has some signs of wear, I have tried to photograph this as best I can. Front glass does have some small marks that I can’t get off but these don’t seem to impact the photos. Lens is in full working order and comes with both front and rear lens caps as well as the lens hood.
