Using A Lens Adapter With My Cannon Point And Shoot...

I use a Cannon A3300 IS Point and Shoot digital camera for taking pictures of everything including coins. I was wondering if anyone has ever tried to use a Lens Adapter with their camera. Here is one I was looking at on ebay: http://www.ebay.com/itm/20083640385....m1423.l2649



It states: Get the most out of your compact digital camera with this handy, universal lens adapter. With this simple attachment, you can easily add auxiliary lenses (such as wide angle and telephoto adapters) and filters that will bring your photos to another level.

Made from lightweight, strong aluminum, this adapter screws into the standard tripod mount of any digital camera. Once attached, the flex joint can be adjusted to fit many compact digital cameras. With the adapter in place, you are now free to attach add-on lenses, filters or step-rings with a 37mm filter thread. Both the adapter mount and L platform are lined with a rubber material to hold your camera firmly in place and prevent scratches.

Has anyone tried anything similar? Also...I'm a novice. Is 37mm a standard for most lenses? Would I be able to get a macro lens that fits a 37mm adapter? Any and all opinions/help is greatly appreciated.
