The Sigma ART 50mm f1.4 is without a doubt the best standard lens with autofocus for Canon or Nikon bodies. You'd expect it to out-perform the cheaper Canon EF 50mm f1.4 USM and Nikkor 50mm f1.4G lenses considering it's roughly twice the price, but the big surprise is how it also delivers better...

Very good to excellent performance across a high-resolution full-frame sensor even wide open; Fast and reliable auto-focus; Minimal light fall-off for an f1.4 lens; Solid build quality; Lower price than professional f1.4 lenses; Chance to fine-tune using optional USB dock; Chance to swap mounts (at...

Higher price than basic 50mm f1.4 lenses; Large and heavy; Not weather-sealed; Some field-curvature makes stopping down mandatory for high-quality shots of flat (or distant) subjects; Outlining sometimes makes the background Bokeh a bit nervous; Greater Longitudinal Chromatic Aberrations than top...

50mm is the focal length most used by doyens like Ansel Adams . This lens justifies it's position for being among the sharpest 50mm ever produced. It's sheer poetry to play with this piece of art. Just wished Sigma started developing weather sealing to it's Art armoury.

I got my D3200 camera a few years ago and it was an incredible leap from the point and shoot cameras I had been using. With young kids, I wanted to be able to get some good photos and especially needed to be able to do so without flash.

My biggest disappointment is very inconsistent AF performance - same picture taken twice from the same position - one is in perfect focus, second is completely soft. Huge vignetting at f/1.4. My first and last attempt buying third party lens. Nothing compare to Canon 50 f/1.2.

nice looking

very inconsistent AF performance

a good 50mm for canon

Excellent tool for three quarter and full length studio shooting, and most work,this is the lens of first choice for day to day shooting both inside and outside. The quality when attached to a full frame FX body is quite unbelievably good,It has been said that this lens is bulky however to achieve...

Although zoom lenses are certainly versatile and convenient, they do have some drawbacks, including relatively small maximum apertures.

I use this on my Canon 6d. This is by far the sharpest lens I've ever used. It doesn't focus as sharp on the outer edges. When you use your outer focus points, it struggles to keep up with Canon's L series lenses.

Until recently, if you wanted a fast quality prime you had to buy from your camera manufacturer. Those days are gone with Sigma now creating quality lenses that are matching, and even surpassing, the quality of the big hitters.

This is an in-depth review of the Sigma 50mm f/1.4 DG HSM Art prime lens that was announced on January 6, 2014 for Sigma SA, Canon EF, Nikon F and Sony A mounts. Ever since Sigma announced its new "Art" lens line, it has been releasing superb new lenses and updates.
