I bought the bag for my EOS M camera, if I want to take this time only with the 22mm fixed focal length (eg cycling). The camera with an attached lens 22mm super fit purely in the pocket. A longer lens, such as the 18-55mm, fits under any circumstances. The bag is hardly noticeable and increases the volume only minimally. They can be opened quickly and the camera can be removed very quickly. One also gets even a spare battery and a second SD card in the pocket and then the removal is no longer quite so simple. The processing of the bag is immaculate, the price / performance ratio (I paid about 25 EUR) I find absolutely justified.
