Chad from Shade Tree Films recently did a quick video review of the Tenba Roadie II Video backpack. The Tenba Roadie II Video Bag was introduced last year is a relatively large 5.5 lb (2.5 kg) bag with lots of room for equipment and accessories.
The bag can hold up to two pro DSLRs, 6-8 lenses (up to a 300mm f/2.8), monopod (although a full tripod could be a little bit harder to squeeze) , shotgun mic, audio recorders and mobile devices. You can even carry larger video cameras such as a RED (Epic or Scarlet), Canon (C100, C300, C500) and Sony (FS100, FS700). There’s also room for up to a 17″ laptop held in its own pocket.
