I don't think so, but this article http://www.amateurphotographer.co.uk/news/Chaplin_sale_ends_Christies_era_news_119409.html seems to suggest a seismic shift in camera collector behavior. What experience do people have of this? Are the traditional blue-chip camera investments (like rare Leicas in mint condition) still holding value, or are they following the general downward trend of the rest of the secondhand market? Or is it that the supply of traditional collector's items is drying up and that more modern cameras (even original Nikon Fs, etc.) are not so interesting to collectors?
