The Sigma 85mm f/1.4 DG DN Art Lens for Sony E is a flagship portrait prime purpose-built for full-frame Sony E-mount mirrorless cameras, delivering the razor-sharp optical performance that Sigma’s Art series is celebrated for. With a blazing f/1.4 maximum aperture, an 11-blade rounded diaphragm, and advanced glass elements including five SLD and one aspherical element, this lens produces stunning subject separation and creamy bokeh that elevates portrait, wedding, and fine-art photography to a professional level.
Engineered for both speed and silence, the integrated stepping motor autofocus system ensures swift, whisper-quiet focusing — ideal for stills and video alike — while the physical aperture ring with de-click switch gives videographers smooth, cinematic aperture transitions. Finished with a weather-sealed body and precision brass bayonet mount, the Sigma 85mm Art DN is built to perform reliably in demanding shooting conditions.
Key features
- Brilliant f/1.4 Aperture: Shoot confidently in low light and achieve dramatic background separation with razor-thin depth of field for compelling portrait imagery.
- Advanced Optical Formula: Five SLD elements eliminate chromatic aberration and color fringing, while one aspherical and four high-refractive-index elements ensure edge-to-edge sharpness and minimal distortion.
- Super Multi-Layer Coating: Effectively suppresses lens flare and ghosting even in harsh backlit conditions, delivering contrast-rich, color-accurate images.
- Fast, Silent Stepping Motor AF: An optimized AF algorithm paired with a stepping motor produces smooth, near-silent autofocus — perfect for video recording and fast-moving portrait sessions.
- Cinematic Aperture Ring: The physical aperture ring with de-click switch allows seamless, silent aperture changes during video, while an aperture lock prevents accidental adjustments.
- Weather-Sealed Build with Brass Bayonet: Robust weather-resistant construction and a precision brass mount deliver professional durability and improved mounting accuracy for long-term reliability.

Frequently asked questions
Is the Sigma 85mm f/1.4 DG DN Art compatible with APS-C Sony E-mount cameras?
Yes. While designed primarily for full-frame Sony E-mount mirrorless cameras, this lens is fully compatible with APS-C models, where it provides an equivalent focal length of approximately 127.5mm.
Does the Sigma 85mm f/1.4 DG DN Art support video shooting with smooth aperture control?
Absolutely. The lens features a physical aperture ring with a de-click switch for smooth, silent aperture transitions during video recording, and its stepping motor autofocus system ensures quiet, seamless focus pulls.
How does the optical design of this lens reduce chromatic aberration and improve image quality?
The lens incorporates five Special Low Dispersion (SLD) elements to markedly reduce chromatic aberrations and color fringing, one aspherical element and four high-refractive-index (HR) elements to control spherical aberrations and distortion, and a Super Multi-Layer Coating to minimize flare and ghosting for sharp, color-accurate results.
