I have a lowe pro mini trekkar to hold a bronica sq-ai with an 80 attached, their hoods,go pro and it's according stuff, film, thats it really. It hold everything well, but it's an awkwardly shaped bag, it's like a big cube on your back. but it's nicely padded to protect stuff. bit hard on your back though. theres a spot for a tripod on the bottom.
