Well... There's no such thing as a neutral density lense, its called a neutral density filter. And it is possible to use both a wide angle lense and a neutral density filter. What you need to do, is see what filter size your built in lense takes: 28mm, 43, 49, 52, 55, 58, 62. Whatever, just look at the BUILT IN lense and it should say what size you'll need. Then you attach the filter first, and lense second. You might have to go to ebay or special order if its a small size lense, like, anything below 49mm. Good Luck.
