This bag represents great value. It currently holds my Canon 550D, two lenses, spare battery, memory cards, a couple of filters, lens cleaning equipment and a small umbrella (really). All in a very compact size. I can verify that it is waterproof, after getting caught in a downpour.
The bag opens conveniently to allow access for quick lens swaps, but the fasteners are a bit of a fiddle to operate with one hand, although they do keep the contents secure.
The bag is very stylish and doesn't look like your standard camera bag, however here is the but; it does look a bit like a handbag. But if you can get over that then it really is a great buy.
