Sigma Corporation is pleased to announce the launch of the new 30mm F1.4 EX DC HSM lens.

This large aperture 30mm F1.4 EX DC HSM lens is designed to match the APS-C size image sensors of digital SLR cameras. Two SLD glass elements are especially effective in the compensation of magnification chromatic aberration.

Glass mold aspherical lens at rear group of lens reduces color aberration and provides high-quality image results. From 40cm (15.7″) minimum focusing distance to infinity, this lens creates very sharp images with high contrast.

The HSM models provide quiet high-speed auto-focus shooting, as well as full-time manual focus. Large Maximum Aperture of F1.4 can perform superbly in a great range of applications, including snapshots, portraiture, indoor shooting and landscape photography.

• Large Maximum Aperture of F1.4
• The most appropriate coating for digital SLR cameras
• Two SLD (Special Low Dispersion) glass elements and an hybrid aspherical lens, provides the utmost correction for all types of aberrations
• Equipped with HSM (Hyper Sonic Motor) system (HSM not included in Sony, Pentax or Four Thirds mounts)
• This large aperture standard lens was exclusively designed for digital SLR cameras featuring APS-C size image sensor

Sigma AF 30mm f/1.4 EX HSM DC – Review by photozone.de

We all know that zoom lenses are compromises regarding speed and performance but we expect fix-focals to perform better than that. Sigma AF 30mm f/1.4 EX HSM DC may perform pretty good in absolute terms but for a fix-focal the lens disappoints a little. The center performance is exceptionally high but the borders are not all that impressive. The other image parameters such as distortions, vignetting and CAs are Okay but nothing to rave about. So at the end of the day the only differentiator is its ultra-large aperture – it’s up to you whether this is good enough compared to classic 28mm or 35mm lenses.

Sigma 30mm f/1.4 review by KenRockwell.com

It works well for its intended purpose: low-light hand-held shooting. Optically it’s not as good for shooting test charts as the Canon or Nikon f/1.4 lenses that cost several times as much, but this is irrelevant because of the tiny depth of field at f/1.4 for photographing real things.

Sigma 30mm F1.4 EX DC HSM Lens review by photoreview.com.au

Although not offering spectacular performance, Sigma’s 30mm F1.4 EX DC HSM produces sharp enough images and has few enough inherent faults to suit most photographers. Compared with other prime lenses it is very good value for its price and its resolution at middle apertures is a match for many of the zoom lenses we’ve tested. The questions potential purchasers should ask are how often they will use the f/1.4 aperture, whether they can tolerate the lack of pin-sharpness shooting at f/1.4 with this lens involves and whether they can live with its limited close focusing distance.
