Between the bag "revolver" Lowepro Toploader Pro 70 AW Cover for good camera just to accommodate a Canon 5D seized with his 24-70 and 24-105 zoom or a backpack able to carry much more equipment (additional objectives computer 17 "etc.) I wanted an intermediate bag for light output, but with the possibility to take a flash and another objective, and portable hand or shoulder ...
This is done with this Mantona bag, where the grip + housing + zoom finds its place by changing the inner compartment.
While there remains much room, but still enough for a flash (580EXII in its case) and another lens (a 85mm Sigma for example) ... and some small accessories.
The bag is well finished and good quality (to judge the long term), and provides good protection to the transported material
Note: The width of the inner bag is closer to 18 than 14cm announced, although with the elasticity of the tissues, it sagrandit the center. So watch for those who would accommodate a subject of more than 15 cm in this direction ...
I thank all the previous buyers who kindly answer my questions on that bag before I decide!
