If you have just the camera to carry with one lens attached to it (you could take an extra one, but it would be a tight fit), then this is the perfect bag.
I was impressed with the quality of the bag, something I honestly didn't expect considering the rather low price. The material is durable, and although I'm not sure if it is completely waterproof, I have used it in light rain without any problem.
It has a few pockets to keep bits and pieces. The only one tiny issue is that the side pockets on the outside aren't all that useful since the shoulder strap clip takes most of the space. It's just about okay to keep tiny stuff.
