Nope. Macro lenses are the way to go.

If not a macro lens, look into extension tubes. You'll be better off. Anytime you add glass in front of your lens, you risk distorting the image. Extension tubes are hollow tubes. It spaces your lens further away from the camera body which in turn allows for closer macro-like focusing. There's nothing between the lens and body but air so there's nothing to distort the image. It also allows you to use any lens you have unlike the diopters which can only be used on a lens that has certain size rings. Something like these are nice cause it has the electrical connections so your lens will still meter and focus. $100 more will get you a decent macro lens though.
