Sigma's mirrorless 135mm Art — reference-class portrait optics redesigned for Sony E-mount.
The Sigma 135mm f/1.8 DG DN Art was released in 2023 as a native mirrorless redesign of Sigma's acclaimed 135mm f/1.8 Art. Designed from the ground up for Sony E-mount, it delivers the stunning optical performance of the original in a package optimised for mirrorless AF systems, with a linear motor for faster, quieter autofocus than the DSLR version.
Optical performance is reference-class. Sharpness is extraordinary from f/1.8 — among the sharpest fast telephoto primes ever tested. The combination of 135mm and f/1.8 produces beautifully smooth, creamy bokeh with outstanding subject separation. Chromatic aberration is virtually absent. This is one of the finest portrait lenses available at any price.
Sony E mount with full electronic communication. Filter thread is 82mm. Weight is approximately 1,035 grams — significant but reasonable for the optical performance. Build quality is excellent with TSC construction and a brass bayonet mount. No weather sealing. The aperture ring has a de-click switch for smooth video operation.
Limited availability on the used market as a newer lens. Prices remain strong reflecting the outstanding reputation. Check AF operation — the linear motor should be fast and silent. An extraordinary portrait and creative lens — the combination of 135mm focal length and f/1.8 aperture at this level of sharpness is virtually unmatched.
