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.

What a lens, haven't really taken it off my d750. Super fast and great for portraits, clean crisp and fast. A little heavy but nothing really to worry about.

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.

From the fast primes that Sigma has introduced so far, this is probably the best one, yet. The resolution is impressive, CAs and distortion are well under control. Vignetting is quite pronounced at large apertures, but that's not really a surprising result for such a fast lens.

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

Slightly fussy rendition of out-of-focus backgrounds under some conditions; No weather sealing

At the time of its launch in 2013, the Sigma 35mm F1.4 DG HSM Art ($899) was a revelation. As the first full-frame prime lens in the company's Global Vision Art series it made a big impact, undercutting other f/1.4 lenses in price without sacrificing image or build quality.

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

Sigma's 35mm f/1.4 DG HSM is the first model in the company's 'Art' series of lenses. Designed primarily for cameras with 'full frame' (36 x 24 mm) sensors, it can also be used with APS-C sensors, where it covers a focal length equivalent to 56mm on Canon cameras or 52.5mm with other brands (Nikon,...

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.
