Stealthing your camera?
It's funny you mention this; I have thought about the same thing in the past. I often go months living out of a small backpack in east euro countries with my trusty nex5. I've been using a cheap no brand inconspicuous strip of nylon as a strap. As for the body, over the years it's collected some old stamps, misc small stickers or paints on various bits. So perhaps it looks more "urbanized" and less enticing now? I'm a little surprised (disappointed?) the body paint has held up as nicely as it has, considering it's been tossed about with no real camera bag for so long; I have a soft sport for ruggedly abused things. Perhaps I may take some sandpaper to the painted metal bits in the future.
Anyway, I did run into this some time ago: http://www.apartmenttherapy.com/camouflaging-your-camera-as-an-85028
