Having bought a Canon 300D I needed a lens that would give me the equivalent to 28mm on a normal 35mm SLR, so I got a Sigma 15mm EX Fisheye lens. The problem is the distortion though not as bad as it would be on a normal SLR, its still very noticeable. Do you think I have done enough in PhotoShop to correct this problem?

Eggiwegs! I would like... to smash them!
