For my new Canon 450D I was looking for a suitable bag for mountain and hiking tours. The bag should be as small as possible, robust and can be used even in bad weather. The telephoto lens 55-250 I transport our tours rather separately in the backpack, because you do not so often used and also the then larger bag is often a hindrance. After much searching, I decided on the basis of the internal dimensions of the Lowepro Apex 110 AW. The camera adjusts the lens 18-55 in transverse position like a glove inside. By transverse position, the camera can take out quickly and above all safely. The amount of listening partition I have so on the ground attached to the left, that the lens rests. This camera is supported everywhere in your pocket and nothing wobbles. Is still room for an additional memory card and similar trinkets. I think our forthcoming holiday will show that the decision was correct.
