Sigma's compact I-Series 35mm f/2 for mirrorless — premium build with metal barrel and de-click aperture.
The Sigma 35mm f/2 DG DN I Series Contemporary launched in 2020 as part of Sigma's premium I-Series — compact metal-barreled primes that prioritise build quality and handling alongside Contemporary-line optics. For Sony FE and L-Mount.
Optically good — sharp from f/2.8 with pleasant rendering at f/2. The I-Series build is premium — full metal barrel with machined finish, aperture ring with click/de-click, and focus ring. Good close focus at 27cm. Stepping motor AF.
Available for Sony FE and L-Mount. 58mm filter thread. Approximately 325g — compact with premium feel. Dust and splash resistant. De-clickable aperture ring. Metal barrel and mount. Minimum focus distance 27cm.
Available used at mid-range prices. The I-Series build quality sets this apart from regular Contemporary lenses. The Sigma 35mm f/1.4 DG DN Art is faster and sharper but larger. For photographers who value build quality and handling in a compact 35mm.
