And I will adjoin this question - at what point for you does the importance of "not looking like a camera bag" override the function of a camera bag? Most "non-camera-bag-looking" bags have other, serious dysfunctions.
- Some are noisy (like Crumplers);
- Some look like other kinds of theft targets (c.f. the Tenbas that look like laptop cases);
- Some have strange reach-in angles or inconvenient access (LowePro Classified, Kata, any flap-over messenger-style case, some newer Tamracs);
- Some are utterly dysfunctional unless your travel pattern is hike, stop for a long time and set the bag on the ground, carefully open it, reverse, repeat (backpack bags);
- Some seriously accelerate abrasion wear and banging around (Domke); and
- Some look like you stole your bag from a 13-year-old schoolgirl (Kipling).
And ironically, some functional bag substitutes are actually not supposed to be camera bags at all. Like when in Salvador, Brazil - where I threw my Fuji GA into a vinyl beach bag that came for free with a bottle of sunscreen....
