I had a chance to play with it this weekend, albeit indoors. It was rainy/dreary/snowing/icy outside, because, well, it's February in Wisconsin, and that's what you get when you live here.
I love this lens. The bokeh is dreamy. This may complete my lens collection. I am certain it will meet my portrait needs, as in, when I have groups of people/families. I had still been thinking about getting the 135mm f/2 L lens, but I may see how this one serves me, and if I see no need, I'll hold off a bit. If I find a really good deal on the 135 (they had it for $899 before Christmas), then I would probably not be able to resist jumping on it, but for now, I have a 50mm f/1.8, this 85mm f/1.8, the Tamron 28-75 (which is a GREAT walk-around and portrait lens), and the Tokina 16-28mm wide angle (f/2.8).
So, alas, here are my three children. My daughter does not always cooperate for pictures, as she's still technically two, but I'm hoping that three is the year to get some amazing pics of her.
You can see that it is just the interior of my house in the background, but I would imagine once I get the kids outside and have some nice foliage in the background, it would give me some amazing bokeh.
