Color Separation on Century Wide Lens?

Hello, folks!

I recently bought the Century Optics Wide lens (the one with zoom-through: .7 I think).

I was pleased with the resulting wide angle, of course, but very alarmed at some major quality issues I see. I'm wondering if this is a problem with the lens itself, the particular lens I got, or my camera.

Take a look at this picture, shot with the Century .7 Wide:

Look at the two circled areas and you will see a substantial amount of color separation in the blue channel. This is most pronounced the farther from the center of the lens, but it is clearly visible and very unacceptable. This particular shot was done in a very darkly lit environment, but I've seen the same effect in a scene shot just after this that was very brightly lit!

What might explain this? Is this normal for a wide angle adapter?
 
Well, no help yet.

Isn't there a Century Optics rep on the board? Failing that, does anyone know if there's a warranty on this thing? If nobody else is having this problem then it may well be my camera, but I'm not willing to assume that just yet.

Tech support for lenses? Anyone?
 
Hmmm...I got something similar with the .6 WA awhile back. I've tried to do it again to post here for help, but couldn't.

I've come to the conclusion that it might have been a case of me not tightening the adapter properly.

When I get home tonight, I'll put up some grabs or a short vid of the prob I saw.

EDIT: See the Red along the right side of the tree? Hmm... But it didn't happen in other shots...after I tightened the adapter. (I was messing witha home-built sunshade for it)
