The D12/c is configured to hold 1pro body with lens mounted, 2 extra pro lens, 1 flash & a 12" powerbook. Front pocket is still empty for 6 cf compartment, 2 big pocket, etc.
This bag can be reconfigured to hold camera with lens mounted, 4 extra lenses, 1 flash w/o notebook compartment. This is because I got 2 different sets of inserts for the 2 configurations. The website for info is here:
