It's not always down to user error

Some lenses have an issue with focusing, either back focusing (actual focus is slightly behind desired focus) and front focusing (actual focus is in front of desired focus). These are much more obvious at large apertures since the DoF is razor thin.

I'm much more interested in the f1.4 shots since any lens goes to f5.6 and more

what makes this lens better or worse then the NIKKOR? I appreciate a good lens, but is between $400 and $500 reasonable for sigma?

I really like the output (pics)...

I was originally going to get the Nikkor (1.4g) but after it finally came out and nobody had it I started looking around, found a positive review on the Sigma, and another and another... before long I had read a lot of great things about it and it was available and cost less than the Nikkor at the time.

I'm sure they are both equally good lenses, I have no regrets and would recommend it to anyone without reservation.

That said, I've only been shooting with my D40 for about 3-4 weeks now and only knew what aperture and shutter speed do for about that same amount of time.



For me, my main goal and purpose for this camera was portraits of the kids - I'm more than confident I can pull that off now.

Your shots seem a bit soft for my taste. How as the lighting? It almost seems as if there is some blur from camera shake\low lighting. Try some shots with an external flash

Handheld, wide open and indoors lol... pretty much a recipe for soft.
