Currently I have the following stored therein:
Camera: Nikon D40 with Sigma 18-200 lens
Lenses: Nikkor 18-55, Sigma 70-300, Lensbaby and accessories
Speedlight, the 10 filter papers, 2 sun visors, various odds and ends (Mini Tripod, grooming equipment, notebook)
Yet even there is room for 1-2 additional lenses.
The backpack is really very comfortable to wear - you hardly notice him on the back. Through the (adjustable) chest and waist strap it is also suitable for cycling without herumzurutschen disturbing. The backpack is very compact (slim!) And well finished. The hook and loop fasteners for the subdivision of the inner life hold good, even after repeated reconstruction. The criticized by some narrow waist belt is not really disturbing, since one anyway never particularly long or particularly often in the "Herausholhaltung" carrying the backpack.
The waist belt to swing the backpack and taking out the camera works! Immediately perfect. Anyone who thinks this, you have to practice a long time, you are wrong. Once strapped on and you can get started.
Even in "normal" rain (tested without equipment) the contents dry as dust - keinerle wetness coming through, thus interfering with the lack of rain cover not (offer other models).
The only drawback is the tripod mount. The backpack can no longer stand on the ground with aufgeschnalltem tripod and the camera is taking - if you are not careful - associated with pain. However, I have had the experience that can be easily attached to the strap at the back of most tripods without the tuck and not wobble even when walking back and forth.
Just buy it from me.
