As you can see in my pictures, this sling bag easily fits my Sony A6700 with a SmallRig cage and a 300mm lens, along with a GoPro and a 18-135mm lens. The size is perfect for this setup, and there is still room for additional accessories like cords, chargers, mice, and eve a pocket for SD cards, though larger ones may not fit as well.
For everyday use and protection from minor bumps or drops, this bag is an excellent choice to keep your gear safe and organized.

K&F Concept's green sling bag is a lifesaver for videographers such as myself who often switch between this new small form factor & our much older bulky equipment. It's just the right size with the ample amount of straps & adjustable velcro dividers. I like that the K&F sling bag is lightweight & waterproof, providing my equipment with optimal protection. I use the top compartment for cables, batteries & microphones while the bottom fits two 360 cameras & two of my HD cams. One last note & a bonus find, on the inside door of the bottom part of the bag is a zippered storage compartment to stow away usb adapters & sim cards. A well thought out camera bag by K&F Concept.

It is a shoulder bag, which has a lot of space, and which can also be personalized, since the separations are made with Velcro, so that, depending on the size of the camera, it can be modified.
It has a large pocket, where the camera will go, and other things, with an interior zipper, which is where I put the battery and cards, and then another upper pocket, which is where I carry cookies, and things for when I go walking. And on one side, the drink bottle, and I am ready to walk and take photos.
The material is good, it is comfortable to wear, it has a hook at chest level, so that it is more secure, and when it comes time to take things out, you release that hook, and then you can move it easily, even carry the whole backpack up to your belly or chest, without taking it off, to take out the camera more easily.

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!

I was looking for a bag to take to the shoot alongside my main backpack. The compartments should be easy to access, and all the most necessary accessories (+water surface or something) should be able to be stored. It should be waterproof or water-repellent. It should be comfortable to carry.

And I found this bag. It meets all of these requirements! Highly recommended!

What I liked:
- Zippers top notch
- Robust workmanship, definitely not "cheap junk"
- Internal compartments can be divided up properly
- Buckles of good quality
- ZV-E10 with telephoto lens for animal photos fits through the side access

There's basically not much more to say because I can't think of anything I wouldn't like. Except maybe the fact that you have to get used to the 1-strap construction. I've only put the bag on incorrectly a few times. I can definitely recommend it and think that my photos here really say more than 1000 words.
5 stars! :)

The K&F Concept camera shoulder bag arrived quickly.

I was looking for a bag that would fit my camera and 500mm telephoto lens well. And that would be easier to carry than a classic shoulder bag, as the weight on my shoulders is too much after a while.

This K&F cross bag is a good alternative. You can wear it across your back or on your front.

My system just about fits in there and there's also room for additional equipment, or a bottle of water and other small items.

It's very good for short trips.

If you are looking for a single shoulder bag for your camera, with a minimum bulk, this is an excellent purchase. Also for the price of €45 at the moment, very good.
I chose the green color and inside there are already well-stored dividers, with the possibility of moving them as desired.
In the upper ""fixed"" pocket, I put documents or microphones or flash (depending on use) and below my Sony A6700 with 2 lenses and relative charger and spare batteries. Above there is also a small ZIP where I hide the spare memory cards.
The backpack is complete like this, also because sometimes I carry with me a ""Backup camera"" (Osmo Pocket 3) and if not ""thrown"" on top of the camera, there is no room for it.

If I mount the 70-350 telephoto lens on the camera, horizontally it is impossible to fit everything in and it is better to leave it disassembled or directly change the order.
This is my typical use and I always carry it with me during photographic work.
If you position the camera perfectly, you can use the side opening to quickly extract the camera and it is the most comfortable thing there (without opening it completely).
Good construction in waterproof Nylon, all in all it is only 10L but well organized, you can carry a lot of equipment.
It can also be used as a travel backpack!
Minimum bulk, maximum performance. Very satisfied and with good padding to safely carry the camera and accessories.

I thought this seemed like a nice smallish bag when I ordered it. However I can honestly say it is an great well thought out little bag.
This works extremely well for me. As well as my camera gear, Mirrorless camera and 4 lenses the top compartment is useful for carton drink, wipes etc.
This is a well designed, good quality bag.

This backpack is very handy for the camera, several lenses and a lot of accessories. My camera with a half-mounted lens fits easily and I can add a wide-angle and a 50mm without any problem, as well as several filter boxes, some small lights and maybe a flash or I can store a mini drone. It also has perfect space for a travel tripod or if you want to carry a bottle of water. It is quite comfortable and for short photo outings you can fit just what you need for that day, avoiding carrying too much weight and as it only has one handle that goes across it is even more comfortable.
It is very well padded, the closure is very comfortable to take out the camera quickly without having to remove the backpack and to be able to store it again easily. The compartments can be moved like in almost any backpack.
It seems to me to be a pretty good backpack for not carrying too much equipment and being comfortable, and I would say that it is slightly waterproof but I have not tried it.
