Looks not so good. The waist belt is just a strap. That means all your weight goes on your shoulders which is not fun. Canvas? Heavy, heavier when wet, long time to dry. I'd never get a pack that is not made from synthetic materials and does not have a least some minimal padding on the waist belt.
really depends on your needs...
I have the f-stop loka for travel which allows me to carry on all my gear including a 400 mm f4. I could hike all day with this. I can include an icu for the camera gear or not. Very nice day pack that is not just a camera bag.
For walk around with a camera and one lens, tiny flash, nd filters I have a hiking quality fanny pack with a slightly padded belt and thick shoulder strap.
That's a very inexpensive bag too @ $80! The f-stop bag that was recommended is on the other end of the spectrum -
f-stop Loka, Matrix Pricing:
Shell Only (No ICU) - $279 // Shell + 1 ICU - $339 // Shell + 2 ICU's $399 // Shell + 3 ICU's $449
There are a TON of alternative bags out there, and a lot of it does come down to your budget. For the most part, and of course there are exceptions, you get what you pay for in a backpack. Weight, comfort, carrying capacity, features and ease of use all come at a price.
Just like when a friend or family member asks me which camera kit, lens, etc, to buy - I ask two important questions which I think we'd need to know to be able to help you.
1. How do you plan on using this bag? More info than just light weight and room for other gear would be helpful. *wink*
2. What's your budget?
Oh, and what exactly are you carrying, both in terms of camera gear and other non-camera related items. So, three questions.
Yes, f-stop is expensive. To answer pixelrandy's questions:
1. 50D or 6D (doubt I'll carry both) + 2-3 lenses (24-105, 100mm, 50mm or 100-400) + misc. stuff like cards, chargers, etc.
2. Budget is open, but I want something that's value for the money
3. In terms of non-camera gear: my computer, snacks, etc.
