not too big , not too small ... just the right size for my dslr , a rather large flash , three extra battery and memory card , and three lens . the bag be well design to protect you camera against rain and bumping . the camera body with lens attach be design to sit on the left side center with the lens run down the middle - the bag 's design be flexible enough to support short stubby lens or the longer telephoto lens . there be two accessory pouch with one up front for battery and memory card and the other up on the cover for anything else . I put my cable , tool , and cleaning cloth up there . the top secure with three rather large strap clip and it come with a nice shoulder strap . there be strap on the left and right which accept accessory pouch from the Tamrac MX line . the fit and finish seem top rate and worthy of year and year worth of service .
