Wide angle lens for for HV30/Letus Extreme

[Dmorison]

Newb here, and an obvious first post.
I recently came across a Letus Extreme 35mm DOF adapter with nikon EOS and canon EF/EF-S mounts for $150 and figured it was a steal and a good investment for my HV30 now that i can no longer shoot on my schools cameras.
Iv since bought a rail system attached to a hands free shoulder rig and all the necessary rings to attach the DOF adapter to the camera and now im looking for a decent wide angle lens.
I've raped the advanced search tool for about an hour and haven't managed to find what im looking for, if there's a thread with what i'm looking for feel free to shoo me in that direction.
Thanks!

Go for anything shorter than 28 mm, and you'll have a decent wide angle.

However, WA + DOF adapter is what I'd call an "oxymoron combination", since they counter each other's effect. A WA gives a deeper DOF, is that what you want?

For WA, I'd skip the DOF adapter and get an accessory WA lens instead (Canon, Raynox).
