Names - AND Pack Drill...
Doesn't need to be that way. Gavin - our Olympus micro 4/3 expert here at the shop - travels with an Olympus micro 4/3 camera and several lenses, but he does not take along the entire optical output, nor does he spend shooting time swapping lenses. He has a sensible mix that really amounts to 2 or 3 lenses as well as the body and some spare memory and electricity. His travel results are superb.
If you'd like to emulate this, talk to gavin here and look at the Olympus E-P3 cameras tat are on special. Then go down to the back of he shop and look at the Lowepro backpacks - specifically the sport ones. Never mind that you are not going to be doing sport - the name is attached only as a sales catch - the bags are perfect for travel/
I've showcased the Flipside Sport 10L AW today. It is a two-strapper with the entry flap against the body. No-one gets to open the bag while you wear it. You can still risk your passport and money on an outside flap if you want to.
The entire inside is a tray - you can pick it out upon release of a velcro panel - and when you do it has a double cinch flap that makes a waterproof parcel of it. Very neat idea.
The most wonderful part of it is the overall weight of the pack - 900 grammes. This is lighter than the laptop that is typing these words.
