For the most part, I agree. I had the AF-D version, and didn't like it. the bokeh was too busy for me, and the lens wasn't sharp when I shot it wide open. Stopped down, it was fine, but I don't buy 1.4 lenses to shoot at f/5.6. That's why I love the Sigma: it's sharp wide open.
i don't know about this lens but it's true for most of their lensesIt's my understanding there tends to be more sample variety among Sigma lenses. They can be good, if you get a good sample, but some have had to swap two or three lenses with their vendor of choice, before getting a sample they could live with.
Does this ring true for people in this thread - regarding this lens?
Honestly, I have leaned away from Sigma due to that since I have no local supplier and not excited about having to ship a few copies back and forth to get a decent one.
Some time back I was looking for a 50. A buddy has a Nikon 50 1.8. I borrowed it for a couple days and was happy to return it to him.
The Nikon 50mm f1/8 was my first lens and it became one of my favorites, as I loved it's sharpness and f-stop range. With extension tube(s) and tripod, I've gotten some great macro shots. That said, it's seeing less camera time, as the 85mm f/1.8 and a newly acquired (from a Cafe member) 105mm macro wrangle for my attention.Some time back I was looking for a 50.

I bought the Sigma 50 1.4 a couple days later and though I haven't shot it much, I love how crisp the shots are at the point of focus and the smooth brokeh.
As BurbonCowboy notes, I didn't buy a 1.4 to shoot it stopped down.
Agreed. If I didn't have the photos I could scroll up and down and compare directly, I really wouldn't have noticed much. The bokeh in the Sigma is better, but the Nikon's isn't bad either. Sharpness difference needs to be pixel-peeped.I think the margin is pretty small - just look at the 50mm G photo thread.
Not every test and not in every criteria. E.g. Thom Hogan's comments:Pretty much every test I've seen has come up with the same conclusion...the siggy is the better lens. ...
Of course, he might have been victimized by a less-than-perfect example of the Sigma. Mark's example has the Sigma being sharper wide-open than the Nikon.Compared to the Nikkor 50mm f/1.4G AF-S the Sigma is less sharp wide open in the center, about as sharp at f/5.6. But the Sigma ramps faster from the poor f/1.4 results to the good f/5.6 results. For example, f/2 is more usable on the Sigma. So it's a tradeoff: if you really need the f/1.4, the Nikkor is the better choice in the center. Beyond that, the Sigma has a slight advantage until about f/5.6, where both lenses are about as good.
