Sigma 50mm f/1.4 DG HSM Art Review


1.    Introduction

There have not been many lens announcements recently that generated the anticipation that the Sigma 50mm f/1.4 DG HSM Art Lens announcement generated. This Sigma 50mm f/1.4 is an optically superb lens. Optically it is the best 50mm, 55mm or 58mm SLR lens I've ever tested.
The build quality of the lens is superb. It feels very solid!
Sigma's Art lenses have an excellent, classy, high-end look and feel and the 50 Art is no different. From the classy mix of matte and gloss black finish to the great-feeling sharply ribbed rubber rings to the smooth overall dimensions, these lenses have very impressive design qualities. 
There is really nothing to complain about in terms of the lens build except one area – weather sealing. While the lens itself probably can take plenty of abuse, the lens mount is not sealed with a rubber gasket like on the new Nikon lenses.

I was a little disappointed with this lens initially as most of the shots I took wide open were not in focus. Later I realized that it was my mistake that I trusted that the AF would be accurate right out of box, which has been the case with my previous Nikon glass. I was wrong.
 
The reason it wasn’t sharp when I looked at the images on the LCD was simply because of the AF not being dialed in. Just as I suspected, it was front focusing quite a bit. Once I had it dialed in to +10, I was ready to give the Sigma 50mm f/1.4 ART another try. 
 
You can refer the below link to test your DSLR for auto focus issues:

After the calibration, I was stunned to see how sharp this lens is. The lens is tack sharp even wide open at f1.4. The contrast and color rendition is just amazing and Sigma Art lenses are made to extract the full output of High resolution cameras like Nikon D810.

The Sigma 50mm f/1.4 features the same high quality hyper-sonic motor (HSM) found on other recent Sigma lenses, which provides fast and quiet autofocus operation. Here is an example of a bubble that I captured in mid air while it was moving:

Sigma 50mm ART beats Nikon 50mm f1.8G in almost every aspect (Image quality, contrast, color rendition and build quality) except focusing speed. Nikon 50mm f1.8 is a little quicker than SIGMA 50mm ART.

6.    Ghosting and Flare

When it comes to handling high-contrast situations with a bright source behind the subject, the Sigma 50mm f/1.4 Art seems to yield quite pleasing results, keeping the contrast levels high and introducing very little ghosting and flare into images. Here is a sample image taken against the sun:

Sigma has really stepped up their game by launching this great lens at a killer price. I would highly recommend this lens for anyone who loves 50mm focal length
