Hey thanks for the kind replies, everyone.

I do have a 28mm lens that I could try reversing. I did not think to do this because of possible wide angle distortion. Is this less of a problem when the lens is reversed? Not that I am doing scientific photography or anything. I guess it doesn't matter that much.

Probably I will just take "pretty much close up" pics with the 28 and the zoom lens for now. Eventually I guess I will go with the micro nikkor 55mm f3.5 and a set of extension tubes.
