I'm looking to get myself into a wide angle lens but I keep hearing about using a photoshop plug-in to correct a fisheye. Will the images be as good as shooting with a normal wide-angle? It would be nice to have the verstality of both a fisheye and a wide-angle in one lens. The two lenses I'm looking at are the Tokina 12-24 AT-X and the Tokina 10-17 AT-X fisheye. I'm looking at these because of the cost and it sounds like the build quality is unrivaled. The wide-angle has some CA issues, but not even much more than the nikkor 12-24 and is easily corrected in PS.
