For the price, I seriously doubt you'll be able to find a better bag with as many features as this one. I'm still going to use my Lowepro as my main bag but this one will make for a fantastic lens bag or as a light day pack. I really like that it includes fully removable inserts so I can fit my 200-600mm if need be. It has a nice little SD slot that's easily accessible from the side with its own zipper. I have to remind myself that this is a $65 bag as it really is quite comparable to some of my more expensive bags. Its a pretty small bag but it uses its space well. The one thing i'm not a huge fan of is the lack of padding in the straps, If you work with a heavier load, this could be a bit of an issue. Its very uncommon to see a rain cover like this one has built in, I like it slightly better than my Lowepro since its detachable (and cleanable). All the compartments are very easy to access, I really like the bottom zipper to access the lens compartment and the side zipper for quickly pulling out a camera body. I think the idea of carrying a tripod is a nice thought but I likely won't use it since this bag really doesn't have the support to handle such a heavy load but its still a great feature to have. All in all, this is probably the best in class for this price point, It doesn't offer a ton of protection but the lens pockets are surprisingly deep and it can easily carry most of my equipment.
Update- Two days after purchase: I had to remove a star due to the low quality stitching along the shoulder straps. I like to mount my V-mount battery along said straps as i do on my Lowepro but, without even attaching the heavy battery, the stitching started coming apart. I would have been less concerned if this was caused by my heavy V-mount battery as this is a pretty off label use but this was caused by my index finger so I think my concern is rather valid. I still think this is a great bag but I'm not so sure about longevity. The shoulder sections really need to be reinforced to ensure the thing won't come apart with my gear inside so I really don't know if I'll be trusting this thing to hold my lenses.
