(If anyone's interested, I've got instructions for modifying this camera (and the Vivitar T100, which is the same camera, re-branded, with a tripod mount) for multiple and bulb exposure here: http://photondetector.com/tools_ref/lex35-multi/ )
I saw on Flickr that other people had been using this camera and I was thrilled, but then I realized that it was a group that was invite-only. Wish it was open.
