Gentec International has announced four new Sigma lenses from their new Art line, which 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. Three of the lenses are designed to maximize the performance of Compact System Cameras (CSC), and one is a large-aperture standard lens for an APS-C format DSLR camera.

High-performance lens system for compact-system cameras

The three new lenses for compact-system cameras (CSCs) are the 19-mm f/2.8 DN wide-angle lens, 30-mm f/2.8 DN standard lens, and 60-mm f/2.8 DN medium-telephoto lens. They make a versatile system suitable for a wide range of photographic pursuits.

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.

System versatility
The 19-mm f/2.8 DN wide-angle lens has an angle-of-view equivalent to 38 mm on the Micro Four Thirds system and 28.5 mm on the E-mount system (35-mm equivalent focal length). The 30-mm f/2.8 DN standard lens has an angle-of-view equivalent to 60 mm on the Micro Four Thirds system and 45 mm on the E-mount system. The 60-mm f/2.8 DN medium-telephoto lens has an angle-of-view equivalent to 120 mm on the Micro Four Thirds system and 90 mm on the E-mount system. Together, the three lenses expand the high-performance options for CSCs.

Superior optical performance and functionality
The simple shape of the focus ring, the use of metal on almost all external areas of the lens, and the unibody design of the hood all add up to a lens design that is ideal for CSCs. Photographers also have the choice of black or silver to match their camera.

Exceptional image quality
The 19-mm f/2.8 DN lens features three glass-mold aspherical lenses, which provide excellent correction for distortion and field curvature. Inspired by the optical design of Sigma’s DP2 Merrill camera, the 30-mm f/2.8 DN lens features two glass-mold aspherical lenses, including a high-quality, double-sided aspherical lens, providing excellent correction for distortion and other types of aberration. The 60-mm f/2.8 DN lens incorporates Special Low Dispersion (SLD) glass to help minimize axial and transverse chromatic aberration. Glass-mold aspherical lenses help minimize coma. All three lenses include an inner focusing system that corrects the fluctuation of aberration to maintain image quality regardless of the focusing position.

Telecentric conscious design
The superior telecentric optical design improves the image quality throughout the frame.

Linear AF motor
These lenses benefit from a linear AF motor that moves the lens unit directly, without the need for gears or other mechanical parts. This system ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photography.

The three new lenses are available in black and silver finishes for Micro Four Thirds and Sony E-Mount compatible cameras. Like all Sigma lenses, they are backed by a comprehensive seven-year Canadian warranty. Available in June, the 19mm F2.8 DN, 30mm F2.8 DN, and 60mm F2.8 DN lenses have suggested retail prices of $219.95, $219.95, and TBA, respectively.

Sigma has also introduced the 30-mm f/1.4 DC HSM large-aperture lens designed for APS-C format DSLR cameras. This large-aperture standard lens, with an angle-of-view equivalent to 45 mm on a 35-mm 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 30-mm f/1.4 DC HSM lens delivers the highest level of image quality worthy of Sigma’s new Art line. The photographer can leverage the shallow depth of field to create beautiful bokeh in snapshots, portraits, landscapes, and many different styles of photography.

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.
