Lens Question (Canon Wide-Converter Wd-58 0.7 X 58)

Hey all!
I was browsing thrift store photo equipment when I ran across this lens.

It was cheap, so I just grabbed it. I knew it was a video camera lens and everything, but I wasn't sure if there was any possible way (lens adapters?) to connect it to my Canon Eos 7d?
I've tried looking and looking, but I can't seem to find anything specific enough.
I can hold it up in front of my lens and take pictures with it (in reverse) and I get an interesting effect like this:

and

So I was just curious if there is any sort of adapter for these types of lenses to dslrs?
Thank you


**Edit:
I found this photo on flickr:

that appears to be a photo taken with this lens attached to an Olympus E-500.
So thats what made me think its possible in the first place.

It should screw onto the front of any 58mm filter thread lens like Canon's 18-55. Hence the x58 at the end.

Essentially it multiplies your focal length by 0.7. So an 18-55 would become a 12.6-38.5mm, though the image quality likely wont be nearly the same.
