Having used this bag now for 6 months I'm still really pleased with it. It provides excellent, all-round, padded protection for the camera, the materials used are strong and hard wearing, it's well constructed, has a strong carrying handle and excellent padded shoulder strap, and the bag and zips are water-resistant so no problem getting caught out in a shower. And if it starts raining heavily, it's supplied with an elasticated water-proof cover - very similar to those you get with a daysack. Others have commented that there isn't really anywhere to store the rain cover. Mine just goes inside at the bottom of the bag, where it takes up virtually no space. Sure you have to take the camera out to retrieve it, but I need it so rarely that it's not a problem. And yes, it's hard to open the bag once the rain cover is on, but if it's raining so hard that I need the rain cover, it's raining too hard to want to take out my camera!
In terms of capacity, I can fit my Nikon D600 with 70-200mm zoom, plus a small wide-angle zoom or prime lens inside the bag all at once (without lens hoods). So it's pretty capacious. The small pockets are fine for extra memory cards and spare lens/body cap or a filter but not much more than that. But that's ideal - if I want to take more stuff, I'll use a proper kit bag. This is intended to provide protection when I just want to take the camera itself.
And finally, it looks discrete and quite stylish (much nicer than it looks in the main photo!). Strongly recommended.
