No it is the Century Optics DS-FEWA-37 Mark II 0.3x Ultra Fish-eye Adapter Lens. It's intended for smaller video cameras. Basically if you are a skater (skateboarder) you will recognize this lens from almost every skate video made after 1989. There are serious color aberrations in the outer region of the image. I had to zoom into get past minor vignetting when you are at maximum wide angle with this lens. I think this makes the colors fall off register at the edges. That said, this lens is really best suited to action sports, small spaces, or to make your subject look pimpin'. So the scene in my example was not the best.

Tiago, I got it from B&H. I'd say yeah it was expensive ($325). You can find them for just under $300 from other stores, but I ordered it with all of the other lenses and it was cheaper to have it shipped together. Don't forget if you are putting it on an HV20 you need a 43 to 37mm step down ring.

Thanks Mark! i will get one ASAP

i'm using the 43-37 step down ring. actually i'm pretty disappointed with the baby death. it was designed for standard def 4:3 camcorders and not HD 16:9. i zoom in a little to get rid of most of the vig but its not good enough for me to be fully satisfied with the $300+ cost. there are also severe color aberrations in the outer regions of the image that make the image quality look bunk. you can see in this vid how crappy it looks: vimeo.com/1861784

I like to use this lens for almost all indoor shooting. Family stuff and so on. For outdoors its just wide enough to open things up.. but not so wide the distortion gets in the way. I use it very often.
