I found out by video of Benjamin Jaworskyj on the backpack. Decisive for the purchase was the access via the back view of safety of the camera. In practical terms this is of course that you do not have to settle the backpack to get at your equipment. Quickly delivered from the dealer and in perfect condition it was now ready. First freed from the box and the foil and then .... Puuuuh which is really great. It then first took a while to adjust the whole strap and attach the variable interior compartments in the right size. Then I grabbed my camera and its accessories in and then ,, still much space ''. Ok fair, I must say I have '' only '' a bridge camera. So I still reingepackt my helmet camera. In short time a listing of what is now everything in it is: In central tunnel my tripod Manfrotto 785B tripod head with aufgestzten (may also be convenient yet a 1.5L bottle are draufgepackt) Camera Panasonic Lumix DMC FZ 72 Adapter tube and a small screwdriver 1.8 teleconverter Close-up lens great Aufsteckblitz with guide number 43 Charger and USB / miniUSB cable Helmet camera and accessories in a big box and now I still have 3 subjects left (one of which is already reserved for an ND filter along with slip-rings) On the bottom of the raincover is housed. On the front there is a large compartment (since I have 2 photo books in it), a middle compartment, two small pockets and there is still the bottom compartment for the actual tripod mount. Also interesting what does the scale, 6.2kg in my case. Of course you can hintendran load the backpack with a huge DSLR a lot of lenses, a small notebook, and with a huge tripod or a relatively small equipment and for other things you need such as hiking. So it's a mix of photo and backpack and maybe my last.
