The diffuser is just under 12.7 cm in diameter. I would have thought the condensor source would have a similar sized business end. My calculator says a full sized 9x9cm slice would require 12.72cm of coverage. I often forget that medium format negatives are never as big as advertised. I would get full coverage on a negative that was 8.83x8.83cm with the dichroic head, William Robb - This message is from the Pentax-Discuss Mail List.
