Bag very well studied. Many pocket with zipper and location for the various and varied accessories. I own a Canon EOS 550D with a 18-55mm zoom, I wanted to opt for the model 102 but not compatible with large zoom. Attention, however, I was surprised that my Tamron SP 70-300mm zoom does not completely returned vertically into the slot provided for this purpose, one can certainly close the bag but the goal is overflowing with approx. 2 cm and therefore a bump on the cover, which seems to me not top-level shocks! Moreover, attention to single strap system, very convenient to rotate the bag (concept of this bag) but tiring if you do a lot of kilometers with this bag full of camera equipment ...!
