focus accuracy compared

I just tried out the focus accuracy of my EF 85m f/1.8 lens on the same test target that was giving my EF-S 17-55mm f/2.8 such a hard time, and sure enough, the 85mm also misfocusses. Not as often as the 17-55, but often enough to show that it's probably the Digital Rebel that's causing the problem.

Still have to think about that lackluster IS though.
