This is a fantastic camera bag. I bought it for my Sony A200, the main section is divided up into three segments of equal size, I have my camera in one, and two lenses in each of the others.
It has has two good sized side pockets, and a large front pocket.
The best thing about the bag is that you can access the main compartment of the bag from the front by way of a zip, very handy because going through the main compartment you first have to take out a stopper that protects your equipment, so handy if you need to grab your camera quick.
The material itself is excellent, and there is a pull out waterproof hood that stretches over the whole bag, but to be honest when I tried to attach it I couldn't get it on!, luckily I haven't taken it in the rain yet.
The bag strap is also very comfortable and won't dig into your shoulder like bags.
Not the cheapest case in the world, I got mine for way below RRP.
