After I have tried in the store the smaller of Jack Wolfskin I ordered this blind. Jack Wolfskin is for the smaller a back length of S / M and for this size of M / L. It fit right away.
The carrying system is designed not only in terms of size to real back, the function of which is super. The back is completely ventilated, the derivation of the weight to the hips works perfectly, the shoulder straps are as they should. If a backpack is properly seated, you can with him at full weight (a short distance) race without losing his seat!
Now to the side issues:
In the photo tray fits a full-frame DSLR and six Objekitve. A 70-200 / 2.8 is to be accommodated, but not ready to fire with an attached hood. In addition, will still need to stay at home a lens.
Other photographic equipment such as cables, flash attachments, filters, mini tripod, etc. fit into the top tray. I think it's much more convenient than with camera bags that are optimized only for Objekitve.
For a tripod, there is a loop and two straps outside of the backpack. The straps can I find rather disturbing, below the upper belt is a loop through which you can simply plug one leg of the tripod and it sits. Unfortunately this is not at all stands not in light tripods. Since then help the further compression straps on the sides.
There are still some pockets for small items. Because I find that for everyday tasks (cell phone, keys, etc.) thoughtful than that for the photo stuff. The memory card slots in the cover of the Photo Tray to go clear, but already for replacement batteries is the solution no longer quite perfect. A specialist in the filter without Box could be stored would be very handy. On these points, other camera bags are also not necessarily better thought out.
A big advantage is the brand. In a Jack Wolfskin a potential thief expected more granola bars, lukewarm coffee and stale socks as an expensive camera!
One drawback is that my laptop does not fit in the laptop compartment. I need him behind, stuff between cushioning and support system. That's too bad, but the shooting remains the home eh.
For each shooting with intent to pack anyway makes sense. You do not always every objective, not everything and not always light tripods. On the way you do not need chargers and laptop makes out more circumstance than sense. And if you really even need anything, the car is usually not far, because do not want to drag you the stuff then.
Conclusion: Finally a backpack that does what you'd expect. The price is also super. Buy!
