I like using eyecups -- I have one on every body I own. But when I got my ZI, the Nikon DK-3 eyecup just would not fit, although the ZI's viewfinder seemed the same size as the Nikon FM2.
Then it dawned on me, why not use the FM2's eyepiece with the DK3 ON the ZI, and use the ZI's eyepiece on the FM2n. EVERYTHING WORKED!!! 😀
The problem was not the thread diameter size or pitch -- it was the depth of the ZI's eyepiece versus the Nikon's. The Nikon eyepiece is deeper, so there is more "thread contact" and thus stays on much more securely.
Long story short -- go to bocaphoto.com and order the Nikon eyepiece for the Nikon FM series. It fits the ZI.
