is ther a good quality wide angle add-on lens out there for the D7i? i have a 400si with a 24m-85mm wide lens and i love it! can i get this out of the D7i or even better 20mm? thanx :P

The A-28 attachment from Olympus... It works relatively well except @ the extreme angle (22mm) where it will vignette!
