SIGMA OFFERS HIGH-PERFORMANCE LENS SYSTEM FOR COMPACT SYSTEM CAMERAS (CSC)
TORONTO, ON., April 15, 2013 – Gentec International announces three new lenses from Sigma designed to maximize the performance of Compact System Cameras (CSC). The 19mm F2.8 DN wide-angle lens, 30mm F2.8 DN standard lens, and 60mm F2.8 DN medium-telephoto lens make a versatile system suitable for a wide range of photographic pursuits. All three lenses are part of Sigma’s Art line, incorporating advanced optical technology to ensure the highest quality images.
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.
The 19mm F2.8 DN wide-angle lens has an angle-of-view equivalent to 38mm on the Micro Four Thirds system and 28.5mm on the E-mount system (35mm equivalent focal length). The 30mm F2.8 DN standard lens has an angle-of-view equivalent to 60mm on the Micro Four Thirds system and 45mm on the E-mount system. The 60mm F2.8 DN medium-telephoto lens has an angle-of-view equivalent to 120mm on the Micro Four Thirds system and 90mm on the E-mount system. Together, the three lenses expand the high-performance options for Compact System Cameras (CSC).
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 Compact System Cameras (CSC). Photographers also have the choice of black or silver to match their camera.
Exceptional image quality
The 19mm F2.8 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 30mm F2.8 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 60mm F2.8 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 7-blade rounded diaphragm creates an attractive round bokeh at large-aperture settings.
Brass bayonet mount
A specially treated brass bayonet mount ensures maximum precision, greater strength, and superior durability for long-term use.
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 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.
