I got my magnifying glass from my dad who found it at a yard sale and paid 50 cents for it. I've never seen one before, but it's made by Bausch&Lomb. One glass gives 20x and both give around 80x. I can use it to view or take pics with. I just hold the glass against the lens and fire away.

I also have the RadioShack scope that zooms from 30-100x. Great pick-up for only $13.
