    I took some pictures with the "d" wide angle converter today. I noticed
    that in most of the photos, there was a significant darkening in the 4
    corners. is that normal even for the "d" wide angle converter?

    It's typical and not the only converter to have that problem.
    I usually fix it with Picture Window Pro http://www.dl-c.com
    Transformation>Grey>Light Falloff.
    Real nice tool that will remember your settings after you find the right
    numbers to make it go away, so you can quickly fix all the shots.

    Out of curiosity, does stopping down (e.g. to f/5.6 or eve f/8) help?

    is brighter.
