The Sigma 30mm f1.4 DC HSM Art Lens is a fast aperture f1.4 lens with an angle of view similar to that of human vision. From 40cm (15.7”) minimum focusing distance to infinity, this prime lens creates very sharp, vivid and detailed images and is suitable for cameras with an APS-C sensor. From an early stage, flare and ghosting are thoroughly measured to establish the design which is resistant to strong incident light such as backlight.

Our Art line delivers high-level artistic quality
Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Designed with a focus on sophisticated optical performance and abundant expressive power, our Art line delivers high-level artistic expression. Developed with the maximum emphasis on artistic touch, 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.
A large aperture F1.4 standard lens
Sigma pioneered the large-aperture APS-C format standard lens category with its 30mm F1.4 lens in 2005. Now that we have reorganized all our lenses into three product lines, we are proud to introduce the fully updated Sigma 30mm f1.4 DC HSM Art Lens. Offering the shallow depth of field of F1.4 and an angle of view extremely close to that of human vision, this lens stimulates the desire to create and is ideal for many different types of photographic expression. The bright viewfinder also aids focusing and composition of images.
Outstanding image quality for enhanced photographic expression
Convenient angle of view of a standard lens challenges photographers’ expression. The Sigma 30mm f1.4 DC HSM Art Lens has outstanding optical performance in order to fully perform its best expressive quality at all shooting distances. Optimized power distribution minimizes field curvature thereby preventing a loss of image quality at the edges of photographs. The use of a double aspheric lens minimizes spherical distortion, astigmatism and coma. Coma of point light sources is minimized near the edge of the image, and an attractive round bokeh effect is produced at large-aperture settings.
Incorporating a Rear Focus system
The Sigma 30mm f1.4 DC HSM Art Lens incorporates a rear focus system that prevents focus-dependent variation in aberration, making high-level image quality possible throughout the entire image. With their unchanging barrel length, these lenses also enhance balance and stability for the photographer. Furthermore, since the front of the lens does not rotate, polarizing filters can be used with extra convenience.
