Every photographer knows the emotional drama as stow. What to pack, backpack or shoulder? Last year I traveled three months backpack in Asia with Macbook and 2 Fuji 4 lenses. Wearing was ok on the daily marches in the sweltering heat, one was not ok-rucksack down to change a lens or times out quickly fetch the macbook. This bag I had already in mind ... only now back, I have dared to buy. It is large compared to the 5 Series, yeah-yeah is a purely Macbook including cable and external disk but it is smaller than a Kata backpack! and the backpack strap criticized lack can be equipped themselves. I'm doing this now 35 years of KB to large screen, suitcases, bags, backpacks ... the digital age, these bags are just awesome. expensive, yes-but each value. Thanks to all reviewers and Harrison / Amazon mistaken for a fast delivery. ps: they are super strong and not look after 10,000 from!
