I buy this bag about 18 month ago because my kit have outgrow my previous bag . I generally carry two Nikon d80 together two battery grip and four lens plus filter , battery charger , lens cleaning kit and so on . one thing that I particularly like be that the bag be long enough so it that will hold two camera body each with a battery grip and lens attach . this mean that I can minimize the time that I have to change lens and so help to keep the dreaded dust away from the camera sensor . the lens that I generally leave attach to the camera be a Nikon 18-200 zoom and a Sigma 10-20 zoom . the internal divider can be move about and reconfigure to suit you own requirement . the top zip down over the main compartment and connect to the side and front of the bag with four plastic clip buckle . there be two side pouch which be still accessible when the main compartment of the bag be all zip up . these be hold close by velco patch . I find these quite useful for thing like a mobile phone that you want use without open the whole case . it can get fairly heavy when load with kit but the shoulder strap and handle do a good job of spread the weight . the bag be within airline carry-on size but be careful if the airline impose a weight restriction on hand luggage . the only disappointing thing about the bag be the so-called ` Piggy-Back Pocket ' which be suppose to allow the bag to be slip over the handle of roll luggage . I can not get this to work - every time I have try to use it the bag swivel round the handle of my luggage . nevertheless , this be a minor problem and I now leave the pocket close and use it to carry a newspaper or magazine . overall , I be very pleased with this bag and would recommend it anybody want a well make camera bag that can carry a large amount of kit .
