NEX Sigma 19mm and 30mm DN Lenses Announced

Here are quick mockups of what the new Digital Neo lenses from Sigma will look like on the Sony NEX-5N. Both prime lenses from Sigma will work with the NEX's autofocus system. The 19mm f/2.8 DN lens translates to an FOV of 28.5mm and the 30mm f/2.8 DN translates to an FOV of 45mm due to the NEX APS-C sensor. Both lenses have a maximum aperture of f/2.8 and f/22 as a minimum. The filter size is also the same at 46mm. The Sigma Digital Neo lens system was announced at CES 2012. We are hoping for more DN lenses soon.

NEX-5N with Sigma 30mm f/2.8 Digital Neo Lens

The Sigma 30mm f/2.8 DN is a 7 element in 5 group lens construction. The lens weighs a mere 4.8 oz (135 grams). The minimum focus distance for the 30mm DN is 11.8 inches which means a maximum magnification of 1:8.1.

This high-performance standard lens is designed exclusively for mirrorless interchangeable lens cameras and has the equivalent angle of view as a 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 EX DN has a minimum focusing distance of 30cm/11.8in and a maximum magnification ratio of 1:8.1.
