Sigma 50-150 f2.8 lens differences.
Dec 30, 2007

I am seriously considering the Sigma 50-150 f2.8 for my 30D. I have the 18-55 2.8 and the 70-200 L IS 2.8 so I'm looking for something in between. What is the difference between the 50-150m f2.8 EX DC HSM and the 50-150m f2.8 EX II DC HSM besides $140.00? I'm probably overlooking something but I have read the specs and can't see it. Also, I have read user opinions and found a few that are not pleased with a front focusing issue. I also read one that says the issue can be handled easily by just not turning the lens past the infinity mark. Any comments on that? I was going to call B&H where I buy but thought I could get some more professional opinions from the forum. Thanks in advance to any replies.
