Finally got a good review.

The Canon EF 15mm f/2.8 Fisheye Lens is currently Canon's only intentionally distorted EF lens.The heavy barrel distortion from the Canon EF 15mm f/2.8 Fisheye Lens creates a special effect that is liked by all people (until it is over-used of course). With digital capture, we can now use fisheye-to-rectilinear conversion software to create a corrected picture equivalent to what a 12-13mm rectilinear lens would yield. This is great but it takes some extra post processing work and requires some knowledge of what the end-result will look like when capturing the shot.

Build quality of the Canon EF 15mm f/2.8 Fisheye Lens is reasonable. The metal mount shows that the Canon 15mm f2.8 fisheye lens is not a bottom of the line lens.
