Sigma 24-70mm f2.8 EX Aspherical DG DF

Review Date: Jun 1, 2007 Recommend? yes | Price paid: Not Indicated | Rating: 8 

Pros: Price, f2.8, Sharp
Soft at 70mm f2.8, Heavy

I bought the Sigma 24-70mm lens few days ago. The performance is very good. However, I noticed that there are some white dots on the edge of the front element. It looks like the colour of the EX finish. These dots do not show up on the pictures.

Is this an issue? Should I bring it back to exchange for a new one?
