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...
Oh, and the sharpness is okay at f2 also :
