Lowepro Photo Sport BP 200 AW II Review - Introduction | PentaxForums.com Reviews
It's a very good bag, a few nice and innovative ideas, a few odd choices. Good comfort, not stellar. Better than average product certainly, however not my first choice. It depends on your needs and intended uses, of course. I cannot compare with version 1, I can say the straps are ok given the size of the bag. The access system is vastly different than on version 1 that's for sure.
In my growing experience, the best 1-day hiking camera backpacks are made by Mindshift Gear. Have a look at their rotation180 system, which is available on many bags. If you want a review to better understand the system, look here:
