This will hold more gear than you ever imagined and a 17" laptop! (Check dimensions for exact size of the compartment). The front compartment will hold a wide angle with a hood attached, a 24-70 2.8 with the hood, a 70 -200 2.8 with the hood reversed, AND two pro size DSLRs in the expandable front pockets (without lenses attached). A regular size DSLR, with a lens attached, can also be carried straight down inside the bag. Strobes or some water bottles fit into the side stretch pockets, as well.
