I was happy to get home from work and tinker with it. Figured out how to load film, fire shutter without film, and activate MLU. I thought the eyecup KEH has was expensive at about $30, so I passed on it. Glad I did, because the Nikon DK-2 fits perfectly on the eyepiece! I had to do an extensive mod to the Pentax 645 eyecup to adapt it to the DK-2. But this one was a perfect fit. On the last photo with the arrows, is this normal for the foam seals to stop there, or is some missing?
