I just got this bag for my camera EOS 550D with a 18-55mm zoom. It is exactly what I wanted. Its installation takes no time unlike a comment on this site made me fear; Indeed, just open the scratch on the back of the cover and move the belt (without having to separate it from the unit) through the slot and open, and then close the scratch. Besides the manufacturer seems proud of this ease of installation because it suggests as a patented feature. In addition to using the device just open the zipper and the cover does not bother taking pictures. But the problem is that these explanations appear in German. I thought the law was required to provide a manual in French ... Also in the small pocket inside I can store a memory card and two USB keys. I also tried to store the card and the battery (without the key): it works without problems. In summary this is a handy holster reasonable price.
Comments (9 November 2012) after a month of travel: the handle is useful; I used alternately with the neck strap.
