Excellent lens, sharp at wide open apertures as others have mentioned. Whether you will notice this extra sharpness compared to a decent prime (like the Nikon f1.4mm AF-D or AF-S) really depends on many other factors: your technique, the conditions, the size of the print or screen etc. And it is big and heavy, it must be said. I am glad I bought this lens, but will not be selling my 50mm AF-D since it is so much more travel-friendly.

The Art series of lenses from Sigma are making quite a splash for both their build quality and optical performance, and this 50 mm 1.4 is stellar in both areas. It is a weighty item, four ounces shy of 2 lb, but I honestly didn't notice that when I mounted it on my camera. The resolution/sharpness is astounding. Shooting my bookcases, hand-held at f8 at at just over 20 ft, I was able to read the title and author in the spine of a paperback. This lens is a beautiful piece of kit.

The Sigma 50 Art is very sharp. I did not require any autofocus fine tune on my Nikon D850 verified by using Reikan Focal software. The sharpest aperture is f4.5 determine by the software. Inhale done any major shoot with it yet but so far so good. I have great expectations.

This lens is super sharp, produces highly useable images even at wide open (F1.4) Focusing is fast and acurate. Construction quality is top notch (though a bit on the heavy side) Great lens for general portraits, pets or kids. Only wish it had image stabilization, then it would be a perfect lens. This lens costs less than half of Nikon 58mm F1.4 or Canon F1.2, and out performs both of them. Did I mention that the bokeh on this Sigma 50mm F1.4 ART is delicious?!

I have many fast, sharp lenses, including several considered best in class for their focal length on a Nikon body. None of them compare to the sharpness and unbelievable low light performance of this Sigma 50mm f1.4 HSM DG Art lens. I highly recommend this lens. It’s in a class of its own.
