I�m still not convinced. The LX mirror box is larger than the 24x36 mm frame. The LX mirror is larger than what MZ-5n or MZ-S have. Maybe it is indeed a typo? Like Antti-Pekka wrote, some telephotos have even larger rear elements but no cut-off. So I�m inclined to think that the cut-off is happening inside the lens. I would need to examine the lay-out diagram of the lens - I found it and I looked at it. Guess what - the 2.8/40 seems to have even larger rear element All the best!
