Sigma 135mm f1.4 DG Art Lens for Sony E Mount

This lens is equipped with an assignable AFL button for personalized controls, along with a focus mode switch and an aperture ring lock. The aperture ring can be adjusted between clicked and de-clicked positions, allowing smooth transitions for video recording. A protective water- and oil-repellent coating on the front element enhances durability when working in difficult outdoor conditions, while a dust- and splash-resistant build safeguards the internal optics. For additional stability, a removable tripod socket compatible with Arca-type clamps is included, which can be swapped with a supplied protective cover when not in use.

The optical design incorporates two aspherical elements and four FLD elements to maintain sharpness and clarity across the aperture range, even when shooting wide open at f/1.4. With 17 elements arranged in 13 groups and a 13-blade rounded diaphragm, the lens produces soft, circular bokeh while reducing vignetting and suppressing color fringing at the edges of the frame. To further improve image quality, Sigma's Super Multi-Layer Coating minimizes flare and ghosting, even when shooting against strong backlight.

Optimized for both photography and video, the lens effectively reduces focus breathing, making it a reliable option for professional cinematography as well as stills. Autofocus performance is driven by Sigma's dual High-response Linear Actuator system, which ensures precise, quiet, and rapid focusing throughout the telephoto range, allowing photographers and videographers to track fast-moving subjects with confidence.
