have now used the backpack on a number of trips, through Israel, in the desert and in Germany on countryside and city tours. I was on the road for a total of 2 months. Appearance: - For me, this K&F Concept camera backpack is one of the most beautiful backpacks on the market. - It has an old look, looks very retro. - It also looks good in photos, this was the primary reason I bought the backpack. The backpack should also look good for photos where I'm on it as a photographer. Size: - It's just under Rynair's second baggage allowance of 35 x 20 x 20 cm. - It can be taken on the plane with you at no extra cost. - As a disadvantage, it is also quite small, I usually travel with large backpacks and luggage of 10-12 kg. - So I slimmed down my equipment and got the following in: In the lower part of the camera: - Full-frame DSLR with wide-angle on it - 2 lenses for DX-Fuji In the upper part: - It's not padded, that's a shame. That's why I installed padding from another photo bag myself and put a Fuji X-T2 with lens in there, as well as a camera cloth. Then still fit in: - 10-inch tablet - 2 remote releases and 2 batteries - wallet - rain protection is on top. Improvement: I prefer a fixed rain cover here, I lost a loose one in the wind on another backpack in Norway last year. All in all, a lot fits in with it, but it's very narrow and I don't think the backpack will survive long hiking tours with it in the long run. As for robustness: - It survived a few drops of rain and dust, but it's too bad for a harsh environment. - It is very filigree, you have to be careful with the backpack. Miscellaneous: - Well constructed with access to the camera from the side without removing the backpack - The magnet clips are great, but also sensitive for long-term use. My conclusion: - A bit tight for my XL size (1.83 cm and over 90 kg), a larger model would be great here, it fits my son perfectly. - But perfect for the flight hand luggage - Very nice design - Could be built a little more robustly for longevity, for example the straps are also very narrow. - Well suited for city tours and smaller landscape tours, but you have to be a little more careful with it. - It fits 2 DSLM or medium-sized DX-DSLRs and accessories. So definitely a top backpack for me, which I will continue to use with smaller photo stuff.
