lightning69: I am liking the pastel-ish color tones and bokeh-priority of your shots.
ieR: Well, the 55-200mm has its pros like weight, size, focusing speed and minimum focus distance.
hinika:
Flare spreads out from the lightsource and leaks onto the rest of the picture.
Ghosting is a 180 degree rotated image of the bright light.
Poor filters cause flare, good filters stop flare.
Poor filters have a lot of ghosting, good filters have little ghosting (but I haven't tried any filter that has
no ghosting.) So if you get ghosting, you will have to remove the filter!
jimlim007: STD dangerous wei! We're talking about the STF LOL.
No, the 55-200mm has a different look from the 70-210mm F4. I would not call the 55-200mm painterly; it's more harsh.
What do you mean the background of the STF is superb sharp? You mean, it is
not hazy like soft focus lenses are? A
Soft Focus lens does this:

This is from the Minolta 100mm F2.8 Soft Focus lens.

Here's one from the Minolta 135mm F2.8/T4.5 Smooth Transition Focus lens. Notice what happened to the Sony 300mm F2.8G SSM in the background - normally, you would see the OOF shape more blockishly with any other lens.
