Thanks, most close-ups I make are of 3D objects, so flat field is not nearly as important to me. I haven't found a flat bug or flower yet, that was still alive. My only concern with the 135L is whether there will be focusing issues with the digital cameras (5D). Not sure why the email text is running together. Maybe my Eudora?
