The 20mm f/2 is part of a new generation of lenses that prioritize both portability and "rendering." While it is small enough for travel and gimbal work, it does not compromise on resolution. It is particularly noted for its ability to capture pinpoint stars in astrophotography and its creamy bokeh when used for close-up wide-angle shots. For Sony users, it offers a distinct, premium alternative to larger G-Master or standard plastic-housed lenses. --- ### Listing Information for Catawiki * **Manufacturer:** Sigma * **Lens Mount:** Sony E-mount * **Focal Length:** 20mm * **Maximum Aperture:** f/2 * **Lens Series:** Contemporary (I Series) * **Condition:** Excellent / Near Mint * **Country of Manufacture:** Japan ---
