The Sigma 30 mm f/2.8 EX DN lens for compact system interchangeable lens cameras produces an angle of view of a 60 mm lens (35 mm equivalent focal length) on the Micro Four Thirds systems and a 45 mm lens (equivalent) on the E-mount system.
Two glass mold aspherical lenses, including a double-sided aspherical lens, provide excellent correction for all types of aberration. 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, delivering sharp, high contrast images, even at the maximum aperture.
The telecentric optical design improves the image quality throughout the frame, says Sigma.
The advanced optical design also allows the lens to be compact and lightweight.
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 30 mm f/2.8 EX DN lens is $269.99. The lens will be available for Micro Four-Thirds in March, in April for Sony E-mount.
