It's not making your picture looks better, but it gives the camera wider capture angle.
In too many cases, you can't move further back when you try to capture an image, forcing you to cut either (say) the bottom of the castle or the top of the castle. Using this lens, because it's wider, you can (for lack of better word) "fit" more image into the frame.
In Canada, the lens and the mount (the mount is needed to mount the additional lens) is selling for US$150 including taxes. Because you're in the US, the taxes will be ommited and after giving you my wholesale price, it will be US$100 including shipping and for a special bonus, instead of padding the item using bubble wrap, I'll pad it with a brand new Yamaha black wool scarf.
note: when the wide-angle lens is being used, flash photography on this camera will become impossible (the lens will be partially covering the flash), so it will be for outdoor shots only.
Of course, once you take the wide-angle lens off, you can use the flash again.
