A good camera bag is important for landscape photography. It needs to be rugged enough to protect all your gear inside, and it should be comfortable to carry for hiking and trekking. My old camera bag is Lowepro Whistler BP 350 AW I. While it is a super rugged bag, I found it has a couple shortcomings for long distance hiking. So I bought Gregory Zulu 40 which is designed to be a hiking and trekking backpack, and I turned it into a camera bag by using camera insert unit from F-stop gear. This combination provides enough gear protection and is also more comfortable for long distance hiking.
