Sigma DG 50mm f/1.4 EX HSM

Amazing performer in XL clothing 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 lens is a masterpiece! 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.

Fantastic lens at a great value 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?!
