Sigma adds 19mm F2.8 EX DN to its lens selection for Compact System interchangeable lens cameras.
Gentec International is pleased to announce the new Sigma 19mm F2.8 EX DN, the second in the growing line of Sigma lenses designed exclusively for Compact System (CSC) interchangeable lens cameras. This wide-angle lens produces an angle of view of a 38mm lens (35mm equivalent focal length) on the Micro Four Thirds systems and a 28.5mm lens (35mm equivalent focal length) on the E-mount system. Three glass mold aspherical elements allow the lens to be compact and lightweight, and provide excellent correction for distortion and field curvature. The inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focal distance. Sigma’s Super Multi-Layer Coating reduces flare and ghosting, and ensures high contrast images. The superior telecentric optical design improves the image quality throughout the frame. This lens benefits from a newly developed linear autofocus motor, which moves the lens elements directly without the need for gears or the drive of other mechanical parts. This system ensures accurate and quiet autofocusing, making the lens particularly suitable for video recording. The 7-blade, rounded diaphragm creates an attractive blur to the out of focus areas of the image. The suggested retail price of the Sigma 19mm F2.8 EX DN lens is $269.99. The lens will be available in the Micro Four-Thirds mount by mid-April, followed later by the Sony E-mount version.   SPECIFICATIONS: Focal Length . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19mm Minimum Aperture . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .F22 Lens Construction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .8 Elements in 6 Groups Angle of View . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 59.3° (Sony E-mount 73.5°) Number of Diaphragm Blades . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 (rounded diaphragm) Minimum Focusing Distance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .20 cm / 7.9” Maximum Magnification . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .1:7.4 Filter Size . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 46 mm Dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
