Summary: Mine is not an "AW" but having owned it for >10 years I feel a review is appropriate. I bought it originally to use with an SLR system (FM2n and AIS lenses) I was 10 years younger then and what seemed like a heavy system (3 or 4 lenses from 20 - 200mm) no longer does. This bag comes close to perfection BUT and it's a big BUT, the harness is awful, as someone else notes.
Summary: I purchased this backpack to replace a Canon brand camera bag I have had for a few years. Once I purchased my second Canon body, and started carrying two bodies and six lenses, along with my flash and other accessories, the old bag had more than reached its limits. This backpack more than handles everything I take along when I go shooting and does it without the pain that a single strap bag can cause.
Pros: Comfortable, Easily Accessible Equipment, Roomy, Strong Construction
Summary: I have used this pack for about two months now and am well pleased. It has more room than I expected with all sorts of pockets and storage compartments. I was able to fit my Konica Minolta 7D plus 4 lenses plus flash plus several filters (Cokin and screw on). The construction is rugged and the weather cover is a nice touch.
Summary: I have the non-AW version, but I bought a simple silicon coated pack cover and voila, AW. Anyway, the bag is solid and takes bumps and scratches no problem. While my gear gets plenty of wear and tear while I'm using it, it feels not a single scratch when in the bag. Padded dividers are easily movable but stay put when you want them to. Filter/battery/card pockets are of useful size, and I love the exterior organizer for pens, cleaning supplies, and food.
Summary: Every backpack is a question of compromises. The compromises in this one are minimal adjustment of the harness, and size. Those are compromises that made this backpack an excellent choice for me since I wanted to be able to carry it on even small regional planes, and my hiking does not exceed a mile or so from the car. The harness is comfortable enough for day hikes and the size is less limiting than I expected while being accepted on every puddle-hopper I have tried.
Summary: Finally I have a place to store and carry all of my camera gear. I am still arranging the compartments, but have been able to get the following packed: Canon Rebel XT body with 17-85 mm zoom lens with hood Canon 10-22 mm zoom lens with hood Canon 70-300 mm zoom lens with hood Canon Speedlite 580EX Miscellaneous filters, cords, batteries, card reader When fully loades, it is heavy.
Pros: Adjustable Harness, Comfortable, Easily Accessible Equipment, Professional looking, Strong Construction
Excerpt: It is also waterproof, so if you’re out in the rain you can stuff an extra t-shirt in the rucksack if you need to change before you get back home. I’ve had mine for several years now and used it at least 200 days a year, so in my opinion the quality is good. The inside padding doesn’t loose its shape even if you have big heavy lenses, so all in all it think it is an excellent choice for a camera rucksack.
Summary: I use this bag as the "carry around everywhere" bag for my DSLR, 580EXII flash, 24-70L and 70-200L lenses. Everything fits well. The only negative I can think of, is that when you add the battery pack to the 30D, the camera and battery pack are too wide/tall to put into the bag comfortably - it causes the bag to "plump" up a little.
Pros: Adjustable Harness, Comfortable, Easily Accessible Equipment, Lightweight, Strong Construction
Summary: This backpack is very light, yet the camera gear is well padded. Great for day hikes. Not a lot of room for other stuff, like lunch, or jackets. A pocket for a water bottle would be nice (as long as it couldn't leak into the cameras). The tripod carrier works well.
