Anyone tried to mount any 3rd party wide angle filter (raynox/vitacom/olympus/etc........) to Nikon D70 kit lense? (18-70mm),

and decreased focal length from (+/- 27) back to 17mm ?

**i Do not know if this work or not.
please correct me if i'm wrong.

i'm wondering thr D70 kit lense is good enough, so, if we can mount those wide angle lense to the kit lense and make it work as wide angle lense, then we should able to DIY our fish eye....
