I've been looking for a suitable photo backpack for a long time, which will meet my current and future requirements. With the K&F backpack in size L, I finally seem to have found a stroke of luck. I will divide my review into the following points: 1. Processing2. Space offer3. wearing comfort1. Workmanship The backpack made a valuable impression as soon as it was unpacked. The zippers are all smooth-running, the seams are well finished. The solution on which the lower tripod holder can be stowed away and the hip belt can be removed is also convincing. The Velcro fasteners used here are great! I also like the option of turning the chest strap upside down to attach it to a Troli. When you look inside, you immediately notice that all compartments are well padded. Both the front compartments for the camera and equipment as well as the laptop compartment at the back. The quick access at the top is also practical, even if it is not an extra access, but only the normal zipper of the main compartment, which is locked by the side straps.2. Space The following things must now be accommodated: 14-inch Ultrabook from Lenovo including charging cable, keychain, wallet, a 2.5-inch hard drive, Lumix G81 including 12-60mm and 45-140mm lens, a flash unit, charger for the camera and flash batteries, various Filter sets (ND, color gradient, grey, CPL and UV), the supplied cleaning set & rain cape, an A5 block, mobile phone charger, the shoulder strap of the camera, a bag with various accessories for the tripod & the tripod itself. In the future 2 lenses will be added, which are just being purchased. As can be seen in my attached photos, the backpack offers enough space for all of this, on the outside you can also carry a bottle with a drink on each side, which was particularly important for me, since I like to do my photo tours a little longer. I also have enough space to have a small first aid kit with me on longer photo tours, just in case.3. Carrying comfort I haven't been able to test the backpack under real conditions on a photo tour, but after receiving it and admitting it, I tried to reproduce it as best I could. Therefore: Everything clean, two additional bottles of water on the side and different clothing combinations. First of all, according to the current season, sweater & thick jacket; at first I was concerned that it could lead to problems here due to my physique (186cm, 100 kg), but that was not the case. All straps are long enough to be properly adjusted. Even if you don't feel everything directly through the thick jacket anyway, I found it very comfortable to have the backpack on my back and didn't feel any restrictions on my freedom of movement. I then tested it with a more airy combination for spring/summer; T-shirt and rain poncho. Again, no restrictions. Of course I had to adjust the straps a bit, but that's normal. The backpack was still easy to carry and didn't restrict anything. Last but not least, the endurance test: just a T-shirt; The backpack is convincing here too, it doesn't scratch or chafe, it doesn't cut in under the arms either. It also seems to give me the impression that it doesn't stick to you right away when you start sweating in summer at higher temperatures, but I can only judge this exactly after the test in summer. I will then adjust the review again if necessary. All in all, the backpack from K&F is well thought out, protects the equipment very well from external influences and is super easy to carry. I'm already looking forward to the first big tour at the end of next month when we go on tour for a day. I will then expand the review again with any points that may arise.
