When it comes to a longer travel, I can perform the following items easily with me.
- MacBook Air 11 inches, including PSU
- Canon EOS 650D including Battery Pack
- EF-S 18-55mm lens
- EF-S 50-250mm Objetiv
- Sigma 17- 270mm
-. Yongunuo YN300 LED including battery charger color layers remote control etc.
- 4 battery for Canon EOS 650D plus 2 chargers
- Samsung ST550 Compact Camera plus charger
- 2.5-inch external hard drive
- Travel tripod 46cm compact
- Nexus 7 (2013) Tablet
- A lot of small stuff
Why 99%? The Gurtmanagement is the only thing that is not perfect. Although only 2 shoulder straps bring sufficient support, however, lacks the relief through a "cross-connection".
Overall, I am more than satisfied.
