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.

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.

a good 50mm for canon

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.

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...

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

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...

We've been very impressed by Sigma's recent 'Art' line lenses, such as the ultra-fast 18-35mm F1.8 DC HSM and the 35mm F1.4 DG HSM . The 50mm F1.4 DG HSM continues in a similar vein, but if anything it surpasses its illustrious stablemates.

Stunning image quality - super sharp; minimal CA and practically no distortion; Impressive flare resistance; Generally attractive rendition of out-of-focus backgrounds; Fast; silent; and accurate autofocus; Excellent build quality

Large and heavy for a 50mm F1.4 prime; Relatively expensive for its class; No weather sealing

The Sigma 50mm F1.4 DG HSM is a fast and tack-sharp lens, both in the centre and at the edges of the frame, with virutally no evidence of chromatic aberrations and very little distortion.

Another fantastic performer. Sigma has been getting serious for some years now, and each and every Art series lens I have bought I have been most impressed with. Some years ago I told myself that I would never sell this or that genuine Canon L series lens in my extensive collection.
