I have a Vivitar 19mm f3.8 lens that was a present from a friend a few years ago and it was so good I'm using it on my desk as a paperweight, however it did give a taste and feeling for ultra wide angle lenses and I subsequently bought a Tamron S.P.17mm f3.5 lens which is IMO one of the best rectilinear ultra wide angle lenses ever made.
