I was looking for an inexpensive second bag for my camera bag. Here I found the bundle with the battery. Since you can always need an appropriate second or third battery and the bundle's only marginally more expensive than the battery alone I ordered the bag. I am very pleasantly surprised, the bag is of good quality and makes a valued and long-lasting impression. In the case of my Sony SLT-A58 fits easily with attached 18-135mm lens, it is even a bit of space for accessories. With skillful arrangement should get the camera with a compact prime lens and a zoom in your pocket. I would recommend buying the bag along with the battery due to the very reasonable price and good quality in any case.
