Sigma introduces the 30mm F1.4 DC HSM large-aperture lens designed for APS-C format DSLR cameras.
Gentec International announces the new 30mm F1.4 DC HSM lens from Sigma. This large-aperture standard lens, with an angle-of-view equivalent to 45mm on a 35mm camera, is a superb go-to lens for an APS-C format DSLR camera and is ideal for many different types of photographic expression. Featuring an advanced design and the latest manufacturing technologies, the 30mm F1.4 DC HSM lens delivers the highest level of image quality worthy of Sigma’s new Art line. The photographer can leverage the shallow depth-offield to create beautiful bokeh in snapshots, portraits, landscapes, and many different styles of photography. SPECIAL FEATURES Art line lenses provide the highest level of artistic expression Sigma is organizing its interchangeable lenses into three product lines: Contemporary, Art, and Sports. The Art line has been designed with an emphasis on artistic expression to meet the expectations of users who value a creative, dramatic outcome above compactness and multifunction. Offering sophisticated optical performance for landscapes, portraits, still-life, close-up and casual snaps, these lenses are perfect for the kind of photography that unleashes the inner artist. While ideal for studio photography, they offer just as much expressive scope when capturing architecture, starry skies, underwater shots, and many other scenes. Large aperture F1.4 standard lens With its shallow depth-of-field and angle-of-view close to that of the human eye, 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 Advanced optical design 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. Rear focus system The rear focus system prevents focus-dependent variation in aberration to ensure high image quality throughout the entire image. The length of the barrel doesn’t change during focusing, which improves balance and stability for easier handling. Since the front of the lens does not rotate, circular polarizing filters are easy to use. Flare and ghosting conscious design Advanced optical design and Sigma’s Super Multi-Layer Coating reduces flare and ghosting and provides sharp, high-contrast images, even in backlit conditions. ADDITIONAL FEATURES Minimum focusing distance of 30cm With a minimum focusing distance of 30 centimetres and a maximum magnification ratio is 1:6.8, this lens is excellent for close-up photography. Hyper Sonic Motor (HSM) The Hyper Sonic Motor (HSM) ensures quiet, high-speed autofocusing, as well as full-time manual focus override by rotation of the focus ring. With the enhanced AF algorithm, smoother autofocusing is achieved. Full-time manual focus is also possible. Rounded diaphragm The 9-blade rounded diaphragm creates an attractive blur to the out-of-focus areas of the image. Ease of use The new ergonomic design offers comfortable grips and unobtrusive yet easy-to-use controls. For improved handling, the design of the lens hood, lens cap, and AF/MF changeover switch have been updated. Brass bayonet mount A specially treated brass bayonet mount ensures maximum precision, greater strength, and superior durability for long-term use. Newly developed “USB Dock” (optional) exclusively for new Sigma lenses Designed for the newest Sigma lenses, proprietary Optimization Pro software allows photographers to update lens firmware and adjust parameters such as focus. Evaluation with Sigma’s “A1” MTF measuring system Replacing an MTF measuring system using conventional sensors, Sigma now employs a proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Previously undetectable high-frequency details are now within the scope of Sigma’s quality control inspections. Made in Japan All Sigma’s manufacturing, including molds and parts, is carried out under an integrated production system entirely in Japan. Sigma is now one of the very few manufacturers whose products are solely “made in Japan”, with each product reflecting a combination of expertise, advanced technology, and genuine craftsmanship. The Sigma 30mm F1.4 DC HSM lens has a suggested retail price of $529.95 and will be available for Canon, Nikon, and Sigma cameras in June. Like all Sigma lenses, the new 30mm lens is backed by a comprehensive seven-year Canadian warranty. For more information about Sigma products, visit www.SigmaCanada.ca.
