If you can't test the MTF curves (big bucks), at various distances from the center to edge, curvature of field, astigmatism, coma, chromatic aberration and numerous other things, you aren't going to be able to tell which lens is "best." Even then, how are you going to know how to interpret it without a degree in optical engineering? The best test in the world is to go out and test the lens in the conditions you shoot in the most. The same light you prefer, and with the film you prefer. Check the results and then go from there. There are no "objective" tests. All are subject to qualification. ========================== Eric Welch Grants Pass Daily Courier
