please pardon my ignorance...
I was thinking of purchasing this as a gift for someone that has a canon sd700is. She can already get incredibly close with this point and shoot in macro mode, so my question is how this works? if it ONLY reduces the focal length so she can get closer, I don't think it would be any value, but if it actually magnifies so she gets a more zoomed in picture without physically getting closer then it might be worth while...
any thoughts?
Thanks!
