- Sigma 35mm F1.2 DG DN | Art lens measures 87.8 mm in diameter and 138.2 mm long (3.46 × 5.44 in) per Sigma's specifications.
- Filter thread is 82 mm. Use these for lens-cap holders, hood adapters, padded case inserts and storage racks.
- Sigma makes this lens for Sony E-mount and L-Mount; the outer diameter is the same, the L-Mount version is 2 mm shorter, and the model above uses the Sony E-mount length.
- No CAD file: the maker publishes only overall sizes, and a plain box or cylinder is not useful design geometry. The table is the published data; parts with real geometry have their own pages.
