so your 15-85 helps you get a static shot at a slow shutter speed in same light with IS..but thats not going to do squat when the subject is moving and you need the shutter speed of the faster 1.4 lens. Also the 15-85 is not going to give you subject isolation like the 30mm will with its 1.4

Of course not. All I was trying to indicate is that as a result of the decentering I could get a sharper image in relatively low light hand held at 1/6 second with the 15-85.

However, all that's changed. In the last 30 minutes a new Sigma 30mm arrived on my door step. I first took a couple of shots and it looked terrific. Very sharp in the center even at f/1.4. I then tested for decentering using a couple of tools. The centering seems dead on at f/1.4. I also tested up to f5.6.

My first opinion of this replacement lens is that its everything the previous one was not. Very sharp in the middle and moderately sharp at the edges wide open. Stopped down to 2.8, depending on the ambient lighting and the distance to the subject, my new copy seems about as sharp across the frame as my 15-85 stopped down. This is preliminary, and I reserve the right to change my opinion. :) I'll post examples later. So far very happy!

The first Sigma 30mm is going back to B&H on Monday.

Do we suppose to receive 3 years warranty card as well? Beach camera sent me 1 year warrant notice and warranty card only. Mine looks sharp to me. I do not have tripod to do scientific focus test.

Register the lens online if you are satisfied with it. IMO, your copy looks great and seems to focus properly.

I also got my Sigma 30mm from Beach Camera and when I registered it online it tells me I have 48 months of warranty remaining...this was the case with the Sigma 17-50mm that I bought earlier this year.

I just got my second copy from B&H. The first copy was decentered and is going back. The Sigma warranty in the box indicates only 1 year, not 4. I will register on line when I'm sure this copy is a keeper, but I'm surprised on line registration would be different from what's in the box.

I'm puzzled by this registration and warranty issue.
I've sent in multiple Sigma lenses that were never registered and were more than 1 year old and still got free warranty repairs, some of these lenses I actually bought second hand here on the forum. I just provided the proof of purchase from authorized dealer and was good to go.

I also got it from Beach camera. Today I tested with live view in low light. My lens makes terrible clicking/grinding noise. They keep grind each other more during the final step (for few seconds before giving green confirmation box). It is some what loud. Feels like EF 35f2 during live view except everything moves inside. Any one noticed this.
Focus seems to be spot on with live view. Looks like a very good option while shooting static subjects.

That is normal for this lens in live view. All lens I have make the sputtering, grinding sound while achieving focus in live view, even my 15-85 USM. The USM motor just goes about it more quietly. The clicks seem to be specific to this lens. I hear it also. I rarely use live view so its not a big issue for me.

Yup. Looks like it is only live view specific issue. I did few more tests keeping eye on distance scale. Lens moves in small steps/increments in live view instead of one go focus movement. Each step produces this tuk noise. It also makes few more steps back and forth before the final focus confirmation. All this tuk tuk noise comes from this small step moves. Some times, this operation takes for few seconds and makes more tuk tuk noise. Probably, it moves in one go during phase AF instead of these steps

Other than this annoyance, live view with tilt screen looks like very useful feature for static subjects. We can focus any where on the screen instead of fixed 9 focus points with phase AF.
