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...

Well worth the money!! I love only had for a few weeks, but I feel it is one of the best investments ever I've made.

Very nice bokeh Third of the price of canon

Not weather sealed

The Sigma 35mm F1.4 DG HSM Art isn't the only third-party option in town. The Tamron SP 35mm f/1.8 has its own set of benefits, including a lower price tag, more uniform illumination, closer focus, and image stabilization.

Very sharp; Wide aperture; Attractive price; Available for multiple camera systems; Solid build quality; Eligible for mount conversion

Heavy vignette effect; Omits image stabilization; Not the best option for ultra-high-resolution cameras

This is an in-depth review of the Sigma 35mm f/1.4 DG HSM Art prime lens that was announced at one of the largest photo shows in the industry, at Photokina in Germany on September 17, 2012 for Sigma, Canon, Nikon, Pentax and Sony mounts.

In late 2012, Sigma re-structured its lens lineup and announced that its future lenses would each be part of one of three new product lines: "Contemporary" for affordable consumer lenses, "Sport" for fast telephoto lenses, or "Art" for high-performance primes and zooms.

Sigma has produced some really fine lenses over the past few years, including the 50mm F1.4 EX DG HSM (which we liked a lot when we reviewed it in 2008 ) and the 85mm F1.4 EX DG HSM . But the 35mm F1.4 DG HSM may possibly be its best yet.

Superb optics that beat anything else in its class; Impressive flare resistance; Fast; silent; and accurate autofocus; Excellent build quality; Very competitive price; Photographers looking for a top-notch; fast 35mm autofocus prime without breaking the bank

Slightly fussy rendition of out-of-focus backgrounds under some conditions; No weather sealing; Anyone who shoots a lot in damp or dusty conditions

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).
