Three new lenses from Sigma are designed to maximize the performance of interchangeable lens cameras (ILC): 19 mm f/2.8 DN wide-angle lens, 30 mm f/2.8 DN standard lens, and 60 mm f/2.8 DN medium-telephoto lens.
All three lenses are part of Sigma’s Art line, incorporating advanced optical technology to ensure the highest quality images.
The 19 mm lens has an angle-of-view equivalent to 38 mm on the Micro Four Thirds (MFT) system and 28.5 mm on the E-mount system.
The 30 mm lens has an angle-of-view equivalent to 60 mm on the MFT system and 45 mm on the E-mount system.
The 60 mm lens has an angle-of-view equivalent to 120 mm on the MFT system and 90 mm on the E-mount system.
Sigma notes the simple shape of the focus ring, the use of metal on almost all external areas of the lens, and the unibody design of the hood all add up to a lens design ideal for ILCs.
The 19 mm lens features three glass-mold aspherical lenses, which provide excellent correction for distortion and field curvature.
Inspired by the optical design of Sigma’s DP2 Merrill camera, the 30 mm lens features two glass-mold aspherical lenses, including a high-quality, double-sided aspherical lens, providing excellent correction for distortion and other types of aberration.
The 60 mm lens incorporates Special Low Dispersion (SLD) glass to help minimize axial and transverse chromatic aberration. Glass-mold aspherical lenses help minimize coma.
All three lenses include an inner focusing system that corrects the fluctuation of aberration to maintain image quality regardless of the focusing position.
These lenses benefit from a linear AF motor that moves the lens unit directly, without the need for gears or other mechanical parts. This system ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photography.
Other features include a 7-blade rounded diaphragm and brass bayonet mount.
The three new lenses are available in black and silver finishes for Micro Four Thirds and Sony E-Mount compatible cameras. Available in June, the 19 mm f/2.8 DN, 30 mm f/2.8 DN, and 60 mm f/2.8 DN lenses have suggested retail prices of $219.95, $219.95, and TBA, respectively.
