I just got my D70S with its kit len. I have few 55mm filters for my FZ5. I am considering getting a 67mm-55mm step-down ring so I can also use these filters for the D70S kit len. Have anyone tried this? I thought maybe the smaller ring might obstruct some light coming in. What are the negative impacts (if any)?

The lens has a certain size, and that is not for nothing. Using step down rings will block part of the image in the corners quite considerably, and it does not seem to be a very good idea.

I'm betting you'd have serious vignetting problems with that size of a step-down.
