Back in the olden days, I used to have a disassembly manual for the Zenit-E on this site, courtesy of photographer, writer and publisher Vladimir Neekeeteen. But after a year in which others had made even better ones, I moved my site and decided it was obsolete. So if you want to learn how to disassemble the Zenit-E, go read Tom Tiger's page.
(And ehm, why take repair advice from me? As you can see on the right, I'm no grand master. Hogs will traverse the skies before I get this camera back together again.)
