Sigma's fastest Art prime — the 135mm f/1.4 DG DN for L-Mount with extraordinary speed.
The Sigma 135mm f/1.4 DG DN Art was released in 2024 as the fastest 135mm AF lens ever produced. At f/1.4 at 135mm, it creates the shallowest autofocus depth of field available at this focal length — exceeding even the legendary 105mm f/1.4 Art 'Bokeh Master' in sheer DOF separation. An extraordinary achievement in optical engineering.
Optical performance is outstanding despite the extreme specification. Sharpness is excellent from f/1.4. The 135mm at f/1.4 produces bokeh of unmatched quality — the subject isolation is in a class of its own. The Art line optical design with multiple special elements controls aberrations remarkably well given the extreme speed. Linear motor AF is fast and precise.
L-Mount, full-frame. Filter thread is 82mm. Weight is approximately 1,635 grams — very heavy but inevitable for f/1.4 at 135mm. Build quality is excellent Art line standard. The aperture ring has a de-click switch. No weather sealing. Also available in Sony FE mount. The rear filter holder adds filtration flexibility.
Very limited availability as a brand new lens. Check AF accuracy — critical at f/1.4 on 135mm. An extraordinary achievement — the fastest 135mm AF lens ever made. For portrait photographers who want the absolute maximum in background separation and bokeh quality, nothing else compares. The weight is the price of optical extremity.
