Sigma 40mm F1.4 DG HSM A Lens - Sony E-Mount

The Sigma 40mm F1.4 DG HSM Art for Sony Full-frame E-mount cameras is Sigma's first lens developed originally to provide the angle of view and performance standard for a cine lens and an interchangeable photographic lens. Sigma's Art line lenses deliver high-level artistic expression. They are designed to meet the expectations of users who value a creative, dramatic outcome above compactness and multifunction. Along with landscapes, portraits, still-life, close-up and casual snaps, they are perfect for the kind of photography that unleashes the inner artist. Ideal for studio photography, they offer just as much expressive scope when capturing architecture, starry skies, underwater shots and many other scenes. This is the ultimate large diameter standard lens that has both 8K compatible resolution and beautiful bokeh.

Optical performance
This lens effectively arranges three FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements to correct axial chromatic aberration and magnification chromatic aberration to the limit. A sharp image is formed on the focal plane with the maximum aperture and contrast with the soft bokeh in the out of focus area highlights the solidity of a subject. With a distortion of 1% or below and a sagittal coma flare corrected to the limit, it demonstrates a consistent optical characteristic over the entire sensor.

High speed AF
The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement.

Rugged design
This lens features a highly effective dust and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing you to work in all types of weather. The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Water and oil repellent coating
The coating on the front and rear lenses incorporate a water and oil repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions.

Compatible with full-frame Sony E-mount cameras
The version of this lens compatible with Sony E-mount mirrorless cameras contains the same optical system as for SLRs. Including in-camera image stabilisation and in-camera lens aberration correction. In addition, the lens is compatible with Sony’s Continuous AF.

Designed to minimize flare and ghosting
Sigma’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
