The bag is very well suited to carry a camera, two lenses and normal extra odds and ends. I get into the pocket of a Canon 100D with EFS 15-85mm and EF 8-15mm a pure. And the EF 40mm also has enough space.
The large zippers are sturdy and good glide. The part can be pleasant on a Speed Belt wear and is not far from the body.
I am very pleased and will probably buy myself a second in order to have more equipment at hand on your belt can.
