It's called recycling! I used to carry a 4*5 Speed Graflex with a roll-film back and a Nikkormat 35mm camera with 3 lenses in mine. Remember all that kind of stuff? All gone. Sold on eBay for a fraction of their historical values, but the bag lives on and carries all the new digital gear, for which I am very thankful. I enjoyed the film era while it lasted, but I wouldn't look back now. It's interesting how the simplest kind of gadget bag, the lowest tech item of the whole lot, survived 5 decades of technical change!
