  1. try your best to use canon body with mirror lock up and use heavy tripot for support. Remove any filters and use the suppied hood and shoot at the mount at f/2.8 or f/4 and see the results. Also exam the lens elements carefully under spot light and see whether any bubbles spread on the lens element. In that case, the element may go wrong and need to send back.
  2. in 1950's lens manufacturer like zoomer or kilar make 400/5.6 Tele-Kilar in exakta mount still proved capable in producing fine lens. Let's look back in history more, steve.
