For my Canon EOS 550D with 18 - 135mm lens I was looking for a bag that is small and handy enough, the camera and the most important small accessories such as extended battery pack, getting started guide or filter easily to take on walks or bike rides.
The camera together with 135mm lens will fit almost but still very good in the pocket when one pushes the Kameratragegurt beside the camera in your pocket.
It is just right and exactly meet my expectations.
