The 12 liter backpack will fit a mirrorless or DSLR camera with 2-4 lenses (up to 70-200mm 2.8) plus an iPad Mini, with space left over for food and other personal items. It also fits the DJI Mavic and other compact drones. Extending the compression straps through the front lash points allows the bag to hold a jacket, blanket or other oversized item on the outside.
