Default What does a fish-eye image look like?

Hi,
I imagine that most people would find this a strange question, so I'll explain. Lately I've been interested in fish-eye photography; so I cobbled together, what I thought, would be a fish-eye lens from my store of old lenses. It's definitely a wide angle, but is it fish-eye? I have my doubts. I would have thought a fish-eye image would bulge out more in the center. (I know that the focus is not good). I'm posting a picture.

If you want it to bulge out more in the center, you need to get closer. The bulge is the perspective distortion that can occur with any lens short of a telephoto. The amount of the bulge is determined by the subject distance and the degree to which the lens is designed to project a rectilinear image.
