Sigma 30mm F1.4 DC DN Contemporary and Sigma 50-100mm F1.8 DC HSM Art, this is the full name of the two new objectives Sigma presented in these days, to be considered very interesting for features that bring a dowry. Let us analyze them one by one to figure out who is addressed and what are the main arrows.

Sigma 30mm F1.4 DC DN Contemporary

Fixed optical lens, 30 mm, high brightness, as evidenced by the maximum aperture F1.4. Designed to offer a refined bokeh, adopts a very quiet autofocus motor, ideal when shooting video. The optical design provides 9 elements in 7 groups, 52mm filters and minimum focusing distance of 30cm fire. Weight 264 grams. Important: the new Sigma 30mm F1.4 DC DN Contemporary Lens will be available to the system Sony E-Mount (going to match a 45mm in full format) for Micro 4/3 bodies (in the 60mm full-frame).

Sigma 50-100mm F1.8 DC HSM Art

Taking up some features from the popular Sigma 18-35mm F1.8 DC HSM Global Vision Art, this new Sigma 50-100 F1.8 zoom (75-150mm equivalent on 35mm format) impresses the brightness notable features fixed lens. The diaphragm "opens" at F1.8 for the entire trip, which makes this extremely interesting target ever. Membership in the Art family out well from any review of the planet, only increases the urge to try one soon.

A level of optics (21 elements in 15 groups) is cited the presence of three lenses FLD ( "F" Low Dispersion), a SLD (Special Low Dispersion), plus other for minimizing aberrations. The autofocus motor is very quiet and fast, according to the statement, while worth mentioning is the ability to mount filters by well diameter 82mm. The weight is well 1491 grams, while the minimum focusing distance is 95cm.

Important: this is designed for SLR cameras DX / APS-C which, depending on the 1.5X or 1.6X multiplier, can enjoy a F1.8 lens with a focal length equivalent to 75-150mm on 35mm format . In this range then fall some historical fixed lenses like the 85mm, 105mm and 135mm, which can be "recreated" with this new zoom without compromising even the iris level (indeed, in many cases resulting in brighter than some F2.8 ). Systems available for Canon, Nikon and Sigma. Should keep promises, this goal may be even "cheap", with its 1099,00 Dollars USA List. Coming into April.
