Here are a few from this past weekend, i shot a company conference here in Boston with my 5D3 and the 200L (whenever possible, i had that lens on almost the entire time). The bokeh is just unreal! Definitely the best portrait lens i've ever come across.

I can finally add an image to this thread, good times!
I haven't tried all that much yet, but got a run in veery foggy grey rainy weather and what amazes me with this lens is the color and contrast and overall PUNCH even in this very dull conditions. And that background is not that far away and just bushes that have always gotten pretty gritty with other lenses. The 200 however, wow...
