The Sigma 30mm f2.8 DN Lens Micro Four Thirds Fit Black is a high-performance, lightweight lens with a large f2.8 aperture and fixed focal length of 30mm. Double-sided aspherical lenses provide excellent correction for all types of aberrations. Sigma’s Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images. The superior telecentric optical design improves the image quality throughout the frame. This lens also benefits from a newly developed linear AF motor which moves the lens units directly without the need for gears or the drive of other mechanical parts. This system ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photos.
