The SIGMA 30mm F1.4 DC HSM, the large-aperture standard lens with an angle of view equivalent to 45mm on a 35mm camera, is a superb go-to lens for artistic photography on an APS-C format digital SLR. Offering a bright F1.4 aperture and an angle of view extremely close to that of human vision, this lens is ideal for many different types of photographic expression. Featuring an advanced design and the latest manufacturing technologies, the SIGMA 30mm F1.4 DC HSM delivers the highest level of image quality worthy of SIGMA's Art line. The photographer can leverage the shallow depth of field that creates beautiful bokeh for portraits, landscapes, and many different styles of photography. 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. The angle of view of a standard lens challenges photographers' expression. The SIGMA 30mm F1.4 DC HSM has outstanding optical performance in order to fully perform its best expressive quality at all shooting distances. Optimized power distribution minimises field curvature thereby preventing a loss of image quality at the edges of photographs. The use of a double aspheric lens minimises spherical distortion, astigmatism and coma. Coma of point light sources is minimised near the edge of the image, and an attractive round bokeh effect is produced at large-aperture settings. 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, polarising filters can be used with extra convenience. From an early stage, flare and ghosting were thoroughly measured to establish the design which is resistant to strong incident light such as backlight. Sigma's Super Multi-Layer Coating reduces flare and ghosting, and provides sharp and high contrast images even in backlit conditions. The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. Optimizing AF algorithm, smoother AF is achieved. It also enables full-time manual focusing capability which allows sensible focus adjustment by simply rotating the focus ring. The new product lines incorporate rubber for the attachment part of the provided lens hood. For better usability, the designs of the lens cap and AF/MF changeover switch have been improved. In order to ensure high accuracy of the product, all metallic parts and the new compound material, TSC (Thermally Stable Composite), which has a high affinity to metal parts, are housed internally. This lens incorporates a brass made bayonet mount which has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term use.
