What can I say? This bag is truly designed for purpose. For the travelling photographer this is an absolute delight. It has so many great features, all of which work!
The best part is the slingshot. Being able to have your camera ready without taking off the bag is brilliant. The bag is designed so everything is to hand in the 'front' position (it also gives you extra support in this position), & yet in the 'back' position everything is nicely padded, won't fall out & doesn't weigh heavy on one shoulder.
There are some nice extras, like the LCD screen protector, & the waterproof, hideaway cover is very useful (especially on any rambling you may do), the bag can be covered & protected in seconds.
There is room for keys, money & phone. Sandwiches & drink would be a struggle! This bag is very compact, if you carry lots of lenses you may want the 200 version. There are some external loops that a tripod could be clipped to (I haven't tried yet).
The bag is listed for a digital camera but you could easily fit a film SLR, lenses & spare film in this too.
Quite simply, this is the best camera bag I have ever used!
