yeah, the 72mm filter on the 135 is pricey ;-). The results are looking good so far tho'

Dan,
DC stands for defocus control. Nikon makes two DC lenses -- the 105 mm f/2 DC and 135 mm f/2 DC.
By turning the DC ring on the lens, you can control the extent of what's out of focus, either in front of or behind the plain of focus, by changing the lenss correction for spherical aberration. Bokeh also varies according to the amount of spherical aberration (under-correction yield smoother bokeh, over-correction yields harsher bokeh), so the DC ring also lets you favour how creamy -- or not -- either the foreground or background will be.
Just going from memory, but I think this is what DC lenses do.
A shot I took with the 105 DC...

Dan,
DC does work, but it's a bit of a gimmick. If you set a 105mm or 135mm lens to f/2 or f/2.8, the background is plenty blurred. The only benefit I see is having some control over where the most of the blurring occurs, in front of the plain of focus in this example --

Dan, in simple terms it makes the doughnut bokeh into smooth bokeh, but you have to choose whether to correct foreground or background. In the photo of Lucy I have chosen to correct the background bokeh, so the otherwise fussy curtain and seat cover patterns are diffused into a mellow glow (to my eyes anyway)
If you overcorrect you can get something like a soft focus lens effect.
I think Joe has nailed the focus and defocus image control on his shot(s) nicely.
Another thing about the 135 is that the front element is even more pleasant to look at than the 85/1.4
cheers

Gimmick ? pah !
