The camera bag from K&F Concept includes an adjustable strap. The bag is black on the outside and grey on the inside.
The bag is suitable for a medium to large camera. With a camera that is not too large you can also carry an additional lens. For a large camera you have to remove the internal division. On the outside there are three small compartments to store photographic accessories such as filters, memory cards or spare batteries. This way the bag has a place for most of what I need for a camera trip.
The fabric of the bag is specified as waterproof. I would say that a little rain does not do anything but looking at the zippers you can see that the bag is not waterproof. However, this is true for most camera bags. To make it completely waterproof you would need an additional cover. The zippers work well. The bag is padded to protect the camera. The bag is quite light.
I noticed two things that could be improved. The strap does not have shoulder padding which is comfortable and necessary when you have a heavy camera or have to carry the bag for a few hours. The strap hooks are made of plastic instead of metal. I do not know how long plastic lasts but metal would definitely be more durable. The quality-price ratio of the bag seems adequate to me.
