omg, what a question. There must be thousands. I must have half of them. I have many that are camera only bags / packs, I always go to Think Tank first. They make stuff like no one else, for pros. I have a huge amount. Unbelievably well thought out, and much is interoperable. I use their belts with pockets for lenses for shooting all the time. I used their undercover bag (Retro 7) for a wedding this weekend. I use their briefcase when traveling on non-photo business. I use there fanny packs, backpacks and airplane bags. I used their airplane roller to store the lenses I am not using. Anyway, ThinkTank first. Although for hiking, I just ordered a Click Elite backpack because it has easy access without taking off the pack and half the pack is for rain gear, gloves, food and the like. It is one of the best combo bags. Think through what you want it for. JD
