Sling bags have only really come into fashion in the last few years and I have already used one from a well-known manufacturer (TT). I couldn't get along with this bag at the time. I was able to test the sling bag from K&F Concept as part of the Amazon Vine program and so I thought I would give this type of photo bag a second chance.

The K&F Concept bag can hold a DSLM with zoom, a fixed focal length, filters, my Osmo Pocket 3 including the battery grip and the small tripod. The outside pocket can also hold a cell phone or a small water bottle. 2 batteries and memory cards can be stored in the only mesh pocket, which is attached to the inside of the side flap.

The sling bag is also quite light and well made. The zippers are easy to use and have sturdy loops. There are enough dividers for the inside so that everyone can divide the bag up according to their needs. This is all well done by K&F.

So why am I only giving it 4 stars? Well, for one thing, I simply need more inside pockets for small items; one mesh pocket is not enough. On the other hand, the straps are just about sufficient for me. I can't imagine what it would look like in winter with a thick jacket. Both the main strap and the stabilizing strap should be 10cm, preferably 15cm longer. I'm not slim, but I'm certainly not fat either. K&F Concept should definitely improve on these two points.

So two stars deducted for that! OK, so why not 3 stars, why 4? Well, no matter what shortcomings the K&F sling bag may have, it does one thing almost perfectly. It sits very well on the body, is easy to fix with the additional strap, is well padded in the shoulder area and doesn't constantly slip into the neck area. I don't know how K&F managed it, but this sling bag is perfect for me in terms of comfort. That gets an extra star.

So is there a recommendation to buy? Yes, I recommend the bag because it feels very, very good to wear, although there is one caveat. If you are tall and strong (or short and fat), the straps will probably not be long enough. Please, K&F Concept, redesign the bag with longer straps, a little bigger and with several inside pockets, then it will be the perfect sling bag. You are so close, now let a photographer take a look at the straps and the small pockets and I will order blind!
