Ok after my first post about the lenses and gear i wanted to get peoples input on a good backpack for the trip. I have sort of decided on bringing my D700 together with the 24-70 and maybe 1 or 2 primes as well as my fuji X20. I have some great bags and own one backpack allready which is really nice to use at home. It is a national geographic explorer bag. It screams photographer a bit too much though and it is a bit fidgety when it comes to get the gear out and not the most comfortable bag for a long trip i reckon. I have looked on the Lowpro flipside sport bags, 15 L size. Only downside i see with those are that they have got not much room for extra stuff like batteries and phone etc. Do you guys have any favorite backpacks for trips? And why? /Martin.
