Actually, it's a variant of the "white car syndrome": the chrome cameras just don't show the wear as obviously as the black bodies do. Insofar as the "war zone" issue goes: For many it reflects the wear and tear of innumerable adventures and a life lived to the fullest (i.e. picture first, dammit!); for others, however, it is something of a fiction: it allows some of the "talkers" and "collectors" (read: the technophiles", and BS artists) to imagine/pretend that they, in the course of their real/
imagined photographic journeying, have extended themselves above and beyond the call of photographic duty to capture that once in-a-lifetime-image, the evidence, of course, displayed for all to see (i.e. the brassed and beat-up camera body).
