My English is not good enough so maybe hard for you to understand me. I meant if I have 70-200 f/2.8L lens and use it. I wasn't taking about fixed 85mm lens."...if I use this lens and shoot at 200mm..." - The EXIF data says that it was shot with a fixed focal length (ie, non-zoom) lens. Maybe u are thinking of another lens u have.
you could try a plugin called perfectly clear , you can set it up for batch processing as an action , i have it set to f2 one push of f2 and they are all done , the default setting would be too your liking based on your colors in your original picture , ps doesnt take that much time the more you use it , and to be honest if you have a really nice image then ps is a must just too tidy up all the little things@Tom:

So, to sum up, the longer FL, the larger blur circle. But I still don't understand the concatenation between the blur circle size and distance. 200mm will make larger blur cirle if photographer stand at the same position of 85mm, but, actually, photographer have to go back further. Somehow, this go-back-further make effect to blur circle, downsize them (smaller), and I don't know this "downsize" is less or more than the "upsize"(larger) made by the longer FL.
One thing I confused, I've learned that wide open aperture make shallow DoF, so if we shoot at f/2.8 then we can have whole boby in DoF to make every details clearly?
@egosbar: Ps is good, but I don't wanna you Ps much because it take me a long time to finish an image, and hard for me to deal with hundred images that way. That's why I want to use ACR so I can Paste Develop Settings for all of the rest, and "BANG!", everything's done, just review and make a few tweak more.
