I'll start with the positives: The backpack is in spite of its compact dimensions, a real storage space miracle. In the many subjects really fit in everything that bears the ambitious amateur photographer with them. For me, it is next to the SLR even two lenses, a flash and various small parts (filters, batteries, cables, etc.). Everything takes place in any professional place. Since the large interior can be designed virtually freely through variably male end "Kettverschluss separators", it remains entirely up to how many compartments he ultimately wants to create here. In addition, the large separate compartment comes under the carry handle that one easily can also be used for a compact video camera.
Also very tidy is the processing of the case. The material is rain-repellent, very durable and the many zippers are meticulously crafted.
The only shortcoming is the comfort, unfortunately for me. Because there is only one strap and beyond just a narrower cross-connection. Although these cross-link ensures that one of the Sling Backpack can not be torn from the back, makes him but not really comfortable to wear. In particular, if you wear a thicker jacket have to be a heavy weight to feel confined by the supporting structure. Here a second strap and a backpack-carrying principle would have been better - but then it would not be a "sling-backpack" more.
That came with no instructions are for me the way, not a nuisance. The backpack is self-explanatory and it is even good that you only discover it in detail before the first use and must discover the many subjects. This speeds up the application if you have suddenly discovered a matching motif.
All in all I am satisfied. The four stars are there in spite of the limited wearing comfort with a clear conscience.
