I bought the bag together with a Sony Alpha 57. The bag is well made and there are also all the parts into the camera and lens. It is very easy. I highly recommend this bag.
Addendum:
After my backpacker holiday in Australia I learned to hate the bag. It is unsuitable for such a vacation. I can only recommend everyone prefers to buy a backpack. It takes too long before you have opened all the locking systems. So you can open the zipper, with the risk of losing anything (happened to me). The strap slip constantly and askew sichsehr quickly. Positive the super water-tightness should be mentioned. All equipment remained dry even in heavy rain.
