Following body replacement off/on-topic from here: http://talk.maemo.org/showpost.php?p...48&postcount=4 Thanks to wonderful supporters, I was just able to cheaply buy a C-mount zoom lens from some USSR-age camera (interesting thing, BTW, it allows zoom with much light going through), that will assist adjustment of C-mount thread. No promises about that one yet, but it seems that interchangeable zoom lenses for N900 camera are closer than ever (for "fat" backcover and/or body replacement - no sane way to fit it into flat cover variant) /Estel
