I also like to know the differences in these two lenses. I've heard that in the first version there is a front focusing issues. Is it corrected in this version?

no difference between versions except the addition of Sony and Pentax mount, everything else is the same. Sigma has also (supposedly) taken care of QC for the second version. I have the first version and am very happy with it on my D300 as well.

I think II has some new coatings minimum focus of 1m is constant throughout the zoom range. Also, some say sharpness at f2.8 is better on the II at 150mm.
I'm probably going to pick up the new version although its quite a bit more expensive.

I'm returnig my 50-150mm 2.8 II. I tried the first version a year and a half ago when it first came out. I actually tried two copies, but it was too soft at 150mm 2.8 and not much better til 5.6. I decided to give Sigma the benefit of the doubt, and ordered the new version last week. I was pretty dissappointed with it, to say the least. Still softish at 150mm 2.8. So it goes back too.
I bit the bullet and bought the 70-200mm 2.8 VR. Its what I always wanted anyway.

I have tried both versions and seen extensive results from each. I own version II.
Comparing the two versions on the a number of bodies I found the the images were significantly sharper on version ll due to three reasons-:
Images with version II had more focus accuracy.
Images of version I are bad - had more CA and was generally softer when in focus especially at the long end.
But also strangely focus was bad in low light with version I - much more hunting.
Also until recently there was no option for on camera fine tuning such is available for the d300 or 5Dii so the images would have always looked soft especially at the long end where image needs more fine tune - near the maximum tune on my d300.
At least my copy makes great wedding photography - when the fine tune is correct - lousy images with a body with no fine tune such as a d90. Tight portraits are quite sharp at 2.8 @ 150mm and images at the wide end are really really sharp.
