All of them are part of the DN series
As you know, Sigma is going to present new lenses on December 1. The manufacturer himself did not name specific models or at least the total number of new products, limiting himself to information that they will be included in the DN series, which unites interchangeable lenses for mirrorless cameras. However, the source corrected the situation: it has already published images of three lenses, which, it is said, will be presented on the first day of December. These are Sigma 24mm f / 3.5 DG DN Contemporary, Sigma 35mm f / 2 DG DN Contemporary, and Sigma 65mm f / 2 DG DN Contemporary. They are said to come with Sony E and Leica L mounts.
