Very small.

Nice backpack, but too small.

This a very good camera bag. It holds both my DLSRs, and my zoom lens. It is very compact but does the job.

I wish it was a bit bigger. Size is OK, but really need more room. Protection padding is excellent.

Nice pack. Good quality build. However it was too small to hold my tripod. So I had to return.

Overall I'm pleased with this backpack. The material is of decent quality and it should hold up in the elements. That being said, I found that space was tight once I started putting a few lenses in. My old camera bag seemed to do a better job for compartments of smaller items. Also, I would have liked to have seen a quick disconnect for the side strap to hold a tripod rather than trying to slip things under the strap. The bag is ok, which is why I give it 4 stars, but I would not run out an buy it again due to the overall layout. One of the pitfalls of shopping online.

Update 12/2/16 - OK folks: now this thing is a steal... on Goldbox deal for $35 bucks I can't recommend this enough. I thought it was great at $52. If you have any doubt, just buy it. You won't be disappointed.Original Review:Love this bag. I spent 3 days looking at pictures and reading reviews of just about every gearbag that Amazon offers. I actually purchased one of the sling bags from a different manufacturer and I returned it because it was too small for my needs and the construction and protection left a lot to be desired. Then, I came across this K&F and based on other reviews (especially the one below with all the pictures), I purchased it and cannot be more happy with the bag. It is strong and well constructed. The zippers are especially smooth and strong. The compartments inside are well padded and the velcro is strong and well stitched to the padding. The padding strips inside are thick and rigid, not like the others that collapse on themselves like butter when the compartment is empty. I fit the following gear in the bag very comfortably: Sony a6000, sony 18-55, sony 55-210, Rokinon 8mm fish eye (very large), Rokinon 21mm (large), sigma 30mm, charger, 2 extra batteries, 3 filter cases, set of grey cards and there's still room for more if I need it. I haven't even put anything in the external pockets. Inside, I can still fit a wallet, phone and a few things if needed. If I get another lens, I'll still be able to fit it. And the best part is that its not a full size backpack. Actually, I just carry it by its handle, like a bag. Eventually, I will use it as a backpack but its size doesn't demand it. Its not heavy, and very importantly, its not overly thick if you put it on your back--have you seen people walking around with backpacks that extend more than a foot off their backs-- Looks ridiculous and is not good for your back and hips. This one stays nice and tight to your body and is compact for easy carrying if you need to. It keeps your center of weight over your legs and feet rather than hanging like an outrigger pulling you backwards. I bet you'll forget you have it on after a while. By the way, I paid full price for this bag and I'm not disappointed. Nobody offered me a free one, oh well, I'm still ahead of the game.

Been using this for a week now and it seems like a solid bag, but it's almost full after 4 lenses, base unit and bits and bobs.If you have a few things you carry around, you might want a bigger bag, but it does feel well made.

I did a lot of shopping around before I purchased this backpack. Personally I find this backpack to have plenty of space. I am an amateur photographer at best. I have one camera base and three lenses along with a flash and a few little extras. This bag is exactly what I was looking for. Everything fits perfectly. Seems well put together and I use the compartment separators to hold the lenses in, in case I pick the backpack up with it open (I never know what I'll do next).I have only owned the backpack for less than a week. If it breaks, I will report back.

Well built. Just the perfect size for 1 camera and 2 - 4 lenses with accessories. Not too heavy one full so it's manageable. Very pleased with this backpack.
