Looking for a fisheye filter for my Canon 17-55 67mm filter front lens. I tried two of those so called fisheye wide angle attachments but they do not render the fisheye effect, round bubble effect so I got my money back, they do not work as advertised.
Does anyone know if there is a screw in filter that gives the fisheye effect? A fisheye lens is far too expensive and that is why I'm settling for a screw in filter that does about the same thing.
