The Manfrotto Pro Backpack 30 is a professional backpack designed for a Pro DSLR + battery grip + 70-200 F/2.8 lens attached, additional camera body, 3 extra lenses, flash, tablet, laptop and accessories. It features the CPS - Camera Protection System - and the Exo-tough multi-layered construction to give the maximum protection.
I put 2 DSL bodies and 4 lens with battery packs and a point N shoot inside this bag with many extra batteries and such.
This holds 2 bodies or more without lens attached. But the main area has my very long lens and body attached.
This lets me take my larger cameras with battery grips attached along with other lens and bodies.
Enjoying this bag so far. Quality of construction is really good, and aesthetically it looks really cool. Only downside to build quality is that it's pretty stiff, so zippers are pretty tight, but will probably relax a but once broken in. I can for two pro bodies in (one with, one without lens attached) along with several more lenses, a flash unit, and various accessories. Haven't tried tripod strap yet, nor have I taken it as an airplane carry- on, but seems like it will fit in overhead just fine, even on the regional jets I find myself on. Overall, very pleased with purchase, delivered in two days by Adorama.
Very light can be used for different lense and change setup. So far noting negative.
