this bag hold more than most bag in term of clean , organized group of equipment . I fit 2 full size dslr -lrb- Canon 1d series body -rrb- . one with lens attach . 5 lens include a 70-200 2.8 , 24-70 2.8 , 17-40 f4 , and 2 prime lens . also pack in the bag be 2 external flash , card , battery , and misc little gadget I use on a regular basis . once fill , it weigh quite a bit , but still feel comfortable consider the weight on my shoulder . this bag be great for long trip when luggage space be limit . I can not stand roller , so I find this to be the best fit for I . for shoot sports\/nature\/portraits \/ etc. . . this bag can take whatever you throw at it . for the price ? it be a no-brainer . I would recommend this bag to anyone who be look for more space to lug camera\/video equipment . my favorite feature of the bag be probably the external pocket which be design so well -lrb- imho -rrb- . they be easy to use and organize with as well . they fit cards\/batteries\/flashes perfectly . it be like they design it specifically for a professional photographer ! who have a thunk ?
