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. 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 as well as provides sharp and high contrast images
even at the maximum aperture. The superior telecentric optical
design improves the image quality throughout the frame. The optical
design also allows the lens to be compact and lightweight. 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. The lens features a rounded 7-blade diaphragm
creating an attractive blur to the out of focus areas of the image.
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.
