Sigma 30mm F2.8 DN ART Lens for Micro Four Thirds Cameras

The Sigma 30mm F2.8 DN Lens for Micro Four Thirds Cameras is a redesigned high-performance standard lens particularly built for Micro Four Thirds systems. It features an aperture range of F2.8-22 with two glass mold aspherical lenses including a double-sided aspherical lens that offers an excellent correction and lessens all types of aberration. The inner focusing system corrects the fluctuating aberration to preserve image quality in spite of the focusing position. Its telecentric optical design develops the better image quality all throughout the frame. Sigma's newly designed Linear Autofocus Motor keeps a fast AF yet in a quiet and accurate focusing. The SLD (Special Low Dispersion) glass helps minimize transverse and axial chromatic aberration. This lens has a focal length of 30mm and 46mm Filter Diameter. 

Product Features in Detail

Metal exterior under the Art category
Redesigned with a metal exterior under the Art category, this high-performance standard lens is designed exclusively for mirrorless interchangeable lens cameras and has the equivalent angle of view as a 60mm lens (35mm equivalent focal length) on the Micro Four Thirds systems and 45mm (35mm equivalent focal length) on the E-mount system.

Glass mold aspherical lenses and double-sided aspherical lens
Two glass mold aspherical lenses, including a double-sided aspherical lens, provide excellent correction for all types of aberration.

Inner focusing system
The inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focal distance. 

Super Multi-Layer Coating
Sigma’s Super Multi-Layer Coating reduces flare and ghosting as well as provides sharp and high contrast images even at the maximum aperture.

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

Optical design
The optical design also allows the lens to be compact and lightweight.

Linear AF motor
This lens benefits from a newly developed linear AF 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 suitable for video recording as well as still photos.

7 blade diaphragm
The lens features a rounded 7-blade diaphragm creating an attractive blur to the out of focus areas of the image.

Maximum magnification ratio of 1:8.1
This Sigma 30mm F2.8 DN has a minimum focusing distance of 30cm/11.8in and a maximum magnification ratio of 1:8.1, and comes in either a silver or black finish.

Digital Neo
High-performance lenses, designed exclusively for mirrorless interchangeable lens cameras.

Aapherical Lens
The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.

Quiet & Fast Autofocusing
This lens uses a motor driven by ultrasonic waves to provide a quiet, high-speed AF.
