This bag was purchased for a small and limited kit at work. I got to do the purchasing so the bag was my choice. It does the job, but its a little smaller than I'd anticipated. Basically it just fits everything, there is no room to grow.
Everything in this case is an XTi, Sigma 17-70, 10-20, and Canon 50 as well as the usual suspects for accessories. The shots below show it with a 300D, 17-40 and 85 in the bag, but there was very little extra room and I'd be worried about maybe loosing protection with things tight up against the inside. Don't even think about using a battery pack, or wanting the camera with a long lens mounted to fit in there. The LowePro website lists the bag as good for a body and lens and 2 extra lenses. This only works if you either own lots of Canon 50 1.8 lenses and want 3 of them with you, or (as I have done) put your smallest lens in the top part.
Other than the comment that its a small bag everything in pretty good. The sling thing does good for comfort with a small bag and makes your kit reasonably accessible.
The bag has an all weather tucked nicely away, a decent size accessory pocket on the front, and then a decent size compartment at the top of the bag. In the main part there are plenty of dividers but customization is limited to keeping them or removing them. There isn't the Velcro on the inside to move from anything aside from their standard layout.
A nice bag if you only own, or want to carry a small amount of equipment. It'd be perfect for a small body (XT/XTi) and a couple of lenses. Sure it fits more but you really start to run out of room. If you've looked at the Slingshots and like to travel light it is certainly a nice bag.
