The backpack is very well laid out. In the upper part fits the food and other things for a day trip. (Who wants to make longer tours, must be based around a slightly larger) The tripod can be made under the backpack. After a short test I can say that it does not hurt there or coming from behind against the body. The camera bag is just right for my e-M10. I've placed my camera incl. Pancake Kit lens, the kit tele and the 45mm fixed focal length lens, cleaning utensils, various filters and a spare battery in the small bag and there is still room for one or two lenses I can not really judge whether it is sufficient for a large SLR.
Next stage of the test would be a greater excursion, if the backpack has bruises or similar exhibits. But as far as I can tell I am very satisfied.
Small Cons: I have a tripod, the width of the bag pack is (which is also not that hard :)). That would probably mean that I would have to carry the tripod in hand in the rain to pull the rain cover over the backpack. But this problem had most backpacks I've looked at, or there is a trick I do not know yet :)
