Offering the highest level of image quality, this large-aperture F1.4 standard lens stimulates the desire to create.
Sigma pioneered the large-aperture APS-C format standard lens category with its famous 30mm F1.4 lens. 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, which offers an angle of view equivalent to 45mm on a 35mm camera. Offering an angle of view and sense of perspective extremely close to that of human vision, this lens stimulates the desire to create and is ideal for many different types of photographic expression. It is a superb go-to lens for artistic photography. Featuring an advanced design and the latest manufacturing technologies, this lens delivers the highest level of image quality.
The full realization of the Art product concept for you to hold in your own hands and appreciate with your own eyes.
Designed with a focus on sophisticated optical performance and tremendous expressive power, our new Art line of lenses delivers top-level image quality. With unsurpassed expressive performance, these lenses reach the high standards demanded by photographers with an artistic, creative inclination. Along with landscapes, portraits, still-life, close-up and casual snaps, they're 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 f1.4 aperture to please any photographer
In 2005, Sigma introduced the SIGMA 30mm F1.4 EX DC HSM large-aperture APS-C format standard lens. Having reorganized its lenses into three product lines, Sigma created the SIGMA 30mm F1.4 DC HSM large-aperture APS-C format standard digital SLR camera lens for the Art line. Like other Art lenses, it offers exceptional optical performance throughout the image. Highly versatile, it lets the photographer use distance from the subject and aperture to achieve many different of photographic expression. For example, the photographer can leverage the shallow depth of field that creates beautiful bokeh for snap shots, portraits, and landscapes, and many different of photography.
Thanks to their easy-to-use angle of view, standard lenses allow photographers to express themselves fully. The SIGMA 30mm F1.4 DC HSM leverages superior optical performance to offer outstanding expressive power at a wide range of focusing distances. Optimized power distribution minimizes curvature of field, 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.
Ultra-high precision and quality—all made in Japan
Optimizing quality with our integrated production system, Sigma is focused on making things right, with our own hands and our own techniques. We are now one of the very few manufacturers whose products are solely "made in Japan." We like to think our products are somehow imbued with the essence of our homeland, blessed as it is with clean air and water, and focused, hard-working people. We pride ourselves on the authentic quality of Sigma products, born of a marriage between highly attuned expertise and intelligent, advanced technology. Our sophisticated products have satisfied professionals and lovers of photography all over the world, because our manufacturing is based on genuine craftsmanship, underpinned by the passion and pride of our experts.
High Build Quality
All lenses in Sigma’s new Art line come with a hood with a high-quality rubberized connector and feature a newly designed lens cap and AF/MF switch, and are designed for intuitive use and superior functionality. Inside, HSM (hypersonic motor) delivers high AF speed and extremely quiet performance. An enhanced algorithm offers even smoother automatic focusing. Full-time manual focus override is another key feature that leaves the artistic touches in the photographer’s hands. The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens. In both the external and internal parts, the optimized use of TSC (Thermally Stable Composite), an excellent match for metal parts, further contributes to the high-precision construction of the lens.

TSC (Thermally Stable Composite)
A first for the industry, the barrel of the lens features a new TSC (Thermally Stable Composite) that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens. TSC also makes possible slimmer forms for parts like zoom rings and scaling rings.
High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
Incorporating a Rear Focus system
The 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.
Flare and ghosting reduction
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. Sigma's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
