I've search and had a look at the various previous suggestions so have a bit of an idea what I want but would like to keep costs as low as possible as this bag will likely be used once in anger 
Most of the time it will be used for transport - not walk around - we will be in a jeep for photos.
I'm going on Safari for two weeks in Namibia. Prefer backpacks and it must be plane carry-on suitable.
- Canon 70D
- Canon 500D
- Sigma 50-500mm lens (large)
- Canon 10-22mm lens (medium)
- Tamron 18-270mm (medium)
- 14" Laptop & charger
- Many spare memory cards, batteries, etc.
At the moment i'm liking the expedition 5 - http://www.tamrac.com/products/expedition5x/ - Can be had for £90 on ebay.
Any other suitable bags?
