I'm editing photos right now that I took several years ago before I got my M9. These are photos for stock so they have to be examined at 100%, corner to corner. The chromatic aberrations of the Canon lenses are driving me crazy!! I'm spending way to much time touching all of that out. I never have chromatic aberrations with Leica lenses. If the photos that you take are going to be examined at 100%, you'd better have the best lenses you can get.
