I used to have an H56, and my dealer loaned me a lens mask. My dealer liked it, but I found that I got a bit of fringing near the edges of the picture, and to my eyes I didn't like it. I'm normally a bit of a sucker for gadgets, but I passed on this one.
Your dealer may lend you one, so ask him if you can try before you buy.
