Unfortunatley when I received the lens in the mail, the Autofocus wasn't working. It took gorgeous photos when in the manual setting but to spend $700 on a lens just to have the Autofocus not work is crappy. The company has other reviews of this happening so it could be a manufacturing issue.

The 35mm f/1.4 DG HSM is Sigma's first large aperture 35mm full-frame lens. It was announced November 2012 and goes head-to-head against the equivalent offerings from Nikon, Canon and Sony.

Outstanding performance in the corners of a high-resolution full-frame sensor even wide open; Good build quality; Quiet and fast AF operation; Relatively low price compared to the big names

Performance at the borders/corners of the DX/APS-C image circle could be better; No weather sealing

The Sigma 35mm f/1.4 DG HSM Art Lens is the first result coming out of Sigma's recently announced lens lineup restructuring. This lens represents a completely new look and feel for Sigma - a very positive upgrade from a physical perspective and a big hit from an image quality perspective.

I wouldn't buy a Sigma lens because I don't trust their lens' long-term viability (I demand that any lens I buy serve me for about 20 years), but if you can get over my personal problems, this consumer-grade Sigma 35mm f/1.4 DG HSM has the same superb optics as Nikon or Canon's professional lenses.

There's something about a fixed focal length lens that brings the photographer out in me. It forces me to move in and back from compositions without resorting to a zoom. Yes, there are times when a zoom is most appreciated-especially the fast constant aperture zooms now available-but a prime puts me...

I recently ran into an issue with my beloved Canon 35mm 1.4 L lens. After many years of exceptional quality and loyal service, it started to back focus when photographing an object or subject from that was more than 3 meters away.

Handling and features This lens is the first of Sigma's new 'Art' line of lenses that promise excellent optical quality and increased creative options thanks to a fast f/1.4 maximum aperture.

Sigma's determined climb from an independent supplier of low-cost lenses to an optics luxury brand enters a new phase with the company's "Global Vision" initiative. More than just a marketing campaign, the program introduces quality-control innovations such as confining all manufacturing to highly...

This lens is part of Sigma's Art line. A fast 35mm/f1.4 lens is an excellent tool for available-light photography indoors or at night outdoors, especially on the full 35mm-film frame (24×36mm sensor, which Nikon refers to as the FX format).

This is the first f/1.4 lens for Nikon that I wouldn't hesitate using wide open, leaving little to be desired. With the possible exception of the 35/1.4 AFS G Nikkor, compared to other f/1.4 Nikkors optics in the 35/50 class, it is relatively free of coma and spherical aberration that hindered wide...

High overall IQ; great AF focus accuracy; very high build quality for a non-OEM lens

Corner falloff wide open; focuses in the opposite direction of Nikkor lenses and lack of weather sealing gasket on lens mount
