Hm, that could mean that your lens or rangefinder may be out of adjustment. Try to shoot a test roll of film with your Ultron wide open, including the shortest possible distance and infinity, and maybe a newspaper on the same distances, print 15*20cm photoes, and you'll see if the infinity is in place. But, judging by the quality of the mark, it just shouldn't be so. However, I saw a new Leica, taken out of its box, with a RF assembled in the wrong way - one of the lenses inside was placed upside down, so it was unable to focus on anything )
