First, the main compartment, which can be accessed by opening the back panel of the bag. As is usual with camera bags, this one contains a series of dividers that attach to the main compartment walls and to each other via Velcro. There are two long dividers that run top to bottom of the compartment to divide the bag into thirds and three short ones that can be used to divide the thirds. By adding a fourth divider from the camera bag I'm retiring in favor of this one, I was able to give myself a 2x3 grid to hold my D3300's body (I have to unscrew the wrist strap and drape it over other compartments), four lenses and one lens ball. The different sizes of the occupants of the different compartments tend to press against each other, and the connections of the various partitions can be a bit imprecise, but everything seems good enough. Each device is snug enough that it doesn't get crowded, but not so tight that it can't be easily removed.

The last third of the compartment formed when inserting the long dividers cannot be divided as the material on that side of the bag will not accept Velcro. The result is a fairly large compartment that's only useful to me as an area to store various accessories that can slide around a bit. I don't normally use a speedlight, but if I did it would probably fit in this compartment quite easily. On the side of this wall are two very small Velcro chambers, each capable of holding almost a battery. (Very handy for me as I carry three with me: one on camera and two in reserve at any given time.)

Most notably there are two pockets that are great for storing a few flat accessories like my gray cards and a couple of cheap plastic filter keys that I thought would be prudent to keep in my pocket. These bags are very loose and everything in them is sure to slip out if the bag is tipped.

There is a separate compartment behind these pockets. The bottom of this compartment is formed by another divider with Velcro. So if you really want to, you can remove these and access them while the main compartment is open. However, you would have to disassemble so much that it's just not worth the effort. This separate compartment is accessed via a zip that runs just a short distance down the side of the bag (further showing that this is intended to be treated as a separate compartment). With the exception of a key fob that can be snapped by a strap, there's nothing in this compartment that would add anchorage or stability to anything you choose to store here. There is also no padding on the top and sides of the compartment. So there is almost no photo equipment there that I would trust. Which isn't really a problem as everything I usually keep in my kit fits in the main compartment. Since I use my camera bag as a personal item when flying, I expect to use this space to store various small items that don't need to be kept secure and that I might need to access on an airplane or in a terminal. It'll be a nice change stuffing stuff like this in my pockets. But otherwise I plan to leave this blank. to use this space to store various small items that do not need to be kept secure and that I may need to access on an airplane or in a terminal.

The inside of the bag's back flap, the part you open to access the main compartment, has a very large pocket that can hold a laptop. As big as this bag is, it's not big enough for my computer (which is fine; I very rarely travel with my computer these days). At least with the configuration of the camera bag I'm using, I would be very concerned that putting a computer in would risk crushing it and/or some of the photography gear. But I'm having a hard time visualizing someone else's computer in there.

Zip the main compartment back up, fold a large flap over the top of the bag and secure the flap with a hook. These hooks seem to hold the flap in place securely enough and aren't too difficult to unhook either, but I really don't see the advantage they offer over a more conventional pair of buckles. Now that the bag is closed, I identify most of the opportunities for improvement. In addition to the confusing hook closure, there appear to be some strange straps. Most are easy to remove and the rest are unobtrusive enough. But what function they are supposed to fulfill is a mystery to me. There's a pair of loop straps at the bottom of the bag that have room for a tripod, and I definitely appreciate that. Before this became commonplace with camera bags, I had to carry my tripod separately whenever I needed it, and it was so annoying that I often just left it behind. There were many occasions when I came across an environment that would have required a tripod and had to forgo the shot instead.

But aside from the tripod straps and a pocket with an elasticated top closure for a water bottle, there's no way to stash anything on the outside of the bag. Not a single zipped pocket of any size, although there are plenty of spots where something like this would fit nicely. It seems like a waste. (What initially looks like a fairly large zippered pouch is just a window into the main compartment of the camera bag, with no Velcro on the side, where I hop around my various accessories. I don't think I'll ever need such quick access to this compartment ; if I ever need something quick to hand, I keep it in the separate zip pocket instead.)

Otherwise, the shoulder straps are adjustable over a wide range, so I think almost everyone will find a comfortable length. I certainly did; and when I say I find it comfortable, that's someone who hasn't worn a backpack more than a few times since I was in high school.

While I've found a few things I can't choose from, the fact is that this bag stores all of my photography gear in a space that's compact, but still roomier than a more conventional over-the-shoulder camera bag. It's comfortable and easy to wear and I don't expect any real issues with it.

The only thing I can't rate right now is how easily it fits under an airplane seat. I don't expect any problems there, but will update this review if needed next time I fly.
