I have been doing photography for 5 years for sure; at first I photographed for myself, and now I photograph for money. I bought myself a Nikon D90, and with it came a bag with a shoulder strap. Oh, how I don't like such bags ... And how the shoulder then falls off from the weight of the camera (it weighs about a kilogram), so carrying bags is extremely inconvenient for me. The backpack itself, the most it is for female photographers. Also at the top there is a convenient handle for which it is quite convenient to carry a backpack. And, of course, the straps. They are very comfortable, soft - they are usually found on school backpacks; comfortable to wear, nothing slips, the back does not get tired. The straps do not chafe the shoulders, do not press, do not squeeze, do not slip. They are adjustable in size. The backpack is comfortable to wear both on one shoulder and on two. Surprisingly, it never bothers me, so that it is not in it. I can run and jump with a backpack on my back without experiencing absolutely any discomfort, and I am absolutely calm for the camera. The outside of the backpack is made of water-repellent fabric. all sorts of little things fit in the backpack freely + there is a lot of space left for, for example, a flash and one more - two lenses (which I do not have).
