Excerpt: I'll admit it, I didn't quite "get" the whole buzz about the Lowepro Slingshot line. And considering that until recently, most of the bags were on the smaller side, I was OK with that, since I'm the sort of photographer who lugs a ton of gear along with me. But then Lowepro released the Slingshot 300 AW (street $99.00), a bag big enough for a DSLR (or two) and a handful of lenses.
Summary: The interior is big enough to contain a decent sized DSLR like a D200 with a telephoto lens, without it getting cramped, the slingshot action is a work of inspiration, and the usual LowePro quality means that the bag will keep your photo goodies nice and dry. It also looks modern and stylish so other lensman won't be laughing as you plod over Rannoch Moor with it on your back.
Pros: Slingshot action, Weatherproof cover, Two internal pouches for cards/batteries, Large external pouches, Lots of room inside, Well designed, Comfy backstraps
Conclusion: This reviewer's biggest complaint about the SlingShot 300 AW is simply that it is a sling bag, and since I often end up wearing a camera bag with a dress shirt (with buttons all the way up the front), I am not a fan of the fact that all sling bags end up putting undue stress on my shirts' buttons. Putting that slightly unfair criticism aside, the Lowepro SlingShot 300 AW is a great bag for anyone in the market for a sling-type camera bag.
Pros: No laptop compartment, No dedicated mobile phone holder, No headphone wire pass-through
Cons: Well-constructed, lightweight design, Comfortable strap and padded waist belt, Big enough to hold professional SLR bodies and lenses, Built-in rain cover, Innovative side access lets you get to your camera without taking off the bag
