I have been looking at some camera backpacks and was hoping I could get some opinions and suggestions. I have already bought one backpack that ended up being to small for my taste and breaking within the first two weeks I had it. Contents: -Canon EOS Elan 7ne ---28-105mm ---17-40mm ---400mm ---Undecided Macro Lens ---Undecided Lens for the 100-300mm range -Film -Filler Flash -Light Meter -Filters -Tripod and/or Monopod -Some Extra Stuff (Snack, Water, ect ) (Words in green I am expecting to get in the future, near and far) I am not 100% sure on my purchases in the future so I could end up with more or less lenses then I believe. The ones I have been looking at are: Pro Trekker AW II (http://www.lowepro.com/Products/Backpacks/allWeather/Pro_Trekker_AW_II.aspx) Photo Trekker AWII (http://www.lowepro.com/Products/Backpacks/allWeather/Photo_Trekker_AW_II.aspx) Dryzone 200 (http://www.lowepro.com/Products/Backpacks/waterproof/DryZone_200.aspx) As you can I want a large bag that can carry my current equipment and my future. I figure if you are going to spend money on a backpack, why not be able to use it more than a year. I will mostly being using the backpack for Hiking in the mountains and for whenever I will need several different lenses with me. And opinions on the bags listed above and suggestions on some other bags are appreciated. Thanks.
