I have the 150 OS and it is a wonderful lens, almost a match for my 135L for portraits! I went from a Tamron 180 to the Sigma. For me it would be a weight/price choice. I really don't miss the extra 30mm at all. The Sigma is almost flawless for what I use it for (bugs, flowers, etc.) Plus, because the bokeh and sharpness are so good, my 135 stayed in the bag for the last wedding that I did.
