Question: Can I sling it atop one shoulder? Sometimes I carry a backpack as well as my camera. I cannot carry both if it can be carried only as a backpack.
Document: I am an avid photographer and received this item as a gift. It is my first backpack style camera bag, as I had been using a shoulder bag style one that carried one body and two lenses. At first, I thought this was a great bag, because I could fit both of my bodies and several lenses, as well as many other accessories. It was also much easier to carry.
I have a Nikon D5100 DSLR with 2 lenses, filters, tripod, and other accessories. I also have a video camera and a Canon PowerShot point and shoot camera. I bought this backpack because I was very tired of carrying around the DSLR case (the kind with the one strap, you carry over your shoulder), and sometimes I would have to carry my video camera case along with it. This gets very tiring and hurts your back, shoulders, and neck.
I purchased this camera bag for my new Nikon D5100, 18-55mm, 55-300mm and 50mm lenses, plus charger, remote, etc. It's light, nicely padded and flexible enough to handle my equipment. I keep it packed and ready to go. The extra compartments are very useful for cell phone, keys, etc. I can sling this bag over one shoulder. It seems well constructed. I have no substantive complaints.
Needed something I could pack a few things and throw over my shoulder. The straps on this backpack came up short. It was okay with both straps on my shoulder, but rode too high for my liking.With one strap on my shoulder, the padding didn't cover my shoulder comfortably. Too bad. Seems like a descent bag, but came up a little short. Literally.I might give the sling bag a try.
I work at a camera store, and even with an employee discount our cheapest bags couldn't beat the price. The ones that came close were either shoulder bags or the one strap "sling" bags that are half the size. This is exactly what I needed, and even though is seemed a bit smaller in person, there was more than enough room for an SLR, 2 lenses, an external flash, a Garry Fong diffuser, a small tripod, a reflector, and all of my other accessories.
Shopped online for several days before deciding on this case. When I received the case I knew I had made the correct decision. Camera and all accessories fit easily. Like the fact that it can be carried with a handle or slung over the shoulder like  backpack. Very durable material with good insulation for your delicate camera stuff. Only wish I had had longer use of it, for someone ripped it off with all my camera stuff inside!
Compartments on side for film if you use it (one of my cameras uses film) and the straps on the side will hold a lightweight tripod or monopod. I have a full sized light Slik tripod and it fit just fine. A larger tripod won't be easily carried however.The shoulder straps are curved, padded and there is a waist strap. The fabric doesn't feel as if it's the thickest, most durable I've ever seen in a bag, but the padding is decent.
Unfortunately, it didn't work out for me like it has for others, and the strap anchoring/stitching started to fail after a week of use. I could have just gotten a defective one, who knows.The more it was carried by the top strap through the streets of Chicago and the airport, the looser it got along with the right shoulder strap. From the user submitted photos, it seems others have stuffed WAY more gear in it than I had when I heard a stitch pop behind my right ear.
I looked at I don't know how many camera back packs, carry bags, rolling bags, all kinds of bags. Based on the reviews I opted for this one. I couldn't be happier. Very nice quality bag and well constructed. Zippers work buttery smooth and the bag seems well padded. Comfortable to carry and with the chest and waist straps it takes a lot of the weight off the shoulders. The shoulder straps are nicely padded as well. The inside swallows a lot of gear.
I packed it up with my camera, and my wife's Nikon, and a bunch of lenses, and the chargers for everything, and my little pocket camera that I sometimes like to use, and some other stuff. It held everything with room for more, and it all felt well protected without being too heavy or bulky to carry around.And when I got home, I thought I unpacked it. Flash forward to a few months later, and I want to charge up my seldom-used pocket camera.
Answer: Yes, it works nicely if you cross connect one of the shoulder straps.
