Re: Canon 17-55mm f/2.8 – tilted lens element?

What f stop? All FL or only 17mm. Decentering, tilted optics, are quite common in my experience. Unfortunate QC problem manufacturers can not seem to overcome. Fixed lens cameras also can have this issue but often masked by the great DOF of small sensors. If the problem is at 2.8 but disappears at 4 or 5.6, you may not be able to do better. Just my experience.
