Okay, please bear with me on this, and read to the end before responding. I am in the market for a photo backpack. I have one at the moment but it is cheap and starting to get a bit ratty. What it does do is hold everything I want to carry, to wit: 1 Domke F5Xb, containing a Fuji X100T, WCL and TCLX100 converters back to back, a pouch with batteries, memory cards, hood and charging cable. 1 Fuji XPro2 with 14, 18-135, 27 and 35 (f2) lenses plus a pouch with batteries, memory cards and card reader. 1 Portable telephone 1 Kindle paperwhite 1 "electronic handbag" (as my wife calls it) with assorted cables, chargers etc for all of the above. 1 shemagh 1 cap, flat, head for the use of 1 folding shopping bag 1 folding umbrella 1 Leuchtturm notebook ('cos Moleskines aren't made like they were) 1 pen 1 set of keys Now, the only time it will be fully loaded like this is when travelling to and from my destination. It must therefore be carry-on baggage compatible. I don't need quick access to the Domke or it's contents while in transit. At my destination I will empty out the bag and either carry it with the XPro2 and lenses and a jumper etc or I will leave it behind and just take the Domke out with me. It must be a backpack. A sling is useless to me partly because it doesn't spread the weight very well and partly because I am left-handed and they all open for the convenience of right-handers. It must be light. It must be robust. It must be discreet. It must be moderately stylish; the ballistic nylon, urban ninja look is anathema to me. Think canvas and leather trim. It must be comfortable - I may need to wear it fully laden while wandering around airports with my main case in tow. I don't mind too much if I have to take it off to access the X-Pro and lenses and value security over accessibility, within reason. I ordered a Manfrotto Perspectives 15 but that did not have enough camera storage space. I'm wondering about some of the National Geographic bags, particularly the Africa medium size but I can't find a local stockist o given a try and I'm not sure about security. Any ideas...?
