Sigma 30mm F1.4 ART DC HSM Lens for Nikon Digital SLR Cameras
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 large-aperture F1.4 standard lens to please any photographer A large-aperture lens with minimal optic aberration and superb peripheral resolution. 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 styles 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 styles of photography. Lens construction Putting a large-aperture aspheric lens first in the series of lenses makes possible a slim barrel, while optimized power distribution helps correct various types of optical aberration. These features give this F1.4 large-aperture lens truly optimal image quality. High resolution and outstanding photographic expression Minimal aberration combined with beautiful bokeh effects at large-aperture settings. 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. Rounded diaphragm When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect—even at large-aperture settings. An all-new, all-premium lineup Superior functionality across the lineup, thanks to Sigma's proprietary new A1 MTF measuring system. There are three requirements for outstanding lenses: fine design, precise manufacturing and inspection that ensures compliance with all specifications. Sigma lenses are born of well-thought-out design concepts and sophisticated, advanced Japanese manufacturing technology; the final clincher is our lens performance evaluation. We used to measure lens performance using conventional sensors. However, we've now developed our own A1 proprietary MTF (modulation transfer function) measuring system using 46-megapixel Foveon direct image sensors. Applying this system, we check each lens in our new lines at our Aizu factory, our sole production site. Even previously undetectable high-frequency details are now within the scope of our quality control inspections, allowing us to deliver consistently high lens performance. 46-megapixel Foveon direct image sensor The 46 effective megapixel (4,800 × 3,200 × 3 layers) and 44 recording megapixel (4,704 × 3,136 × 3 layers) 23.5 × 15.7mm APS-C X3 direct image sensor captures all primary RGB colors at each and every pixel location, ensuring the capture of full and complete color. Using three silicon-embedded layers of photo detectors, stacked vertically to take advantage

Offering the 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 photography. Equipped with the latest in lens technology, the 30mm 1.4 lens boasts a Hyper Sonic Motor (HSM), Super Multi-Layer Coating and a design featuring Thermally Stable Composite Material (TSC). The HSM ensures quiet, accurate and high-speed autofocus; the Super Multi-Layer Coating reduces flare and ghosting, while the TSC reduces expansion and contraction of the internal lens barrel. A rear focus system 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. An optimized autofocus achieves a smoother focusing. The 30mm 1.4 has a minimum focusing distance of 11.8in and a maximum magnification ratio of 1:6.8. A 9 blade rounded diaphragm creates beautiful bokeh. Under the Global Vision standard, every lens will be tested before shipping using the Sigma A1 MTF system to ensure the highest degree of quality possible.
