I'm going to be spending the holidays in England, and I need to find a camera bag to lug all my stuff over there that can be taken as carry-on. To start, here's a list of my gear:
Canon 40D w/BG-E2N
Tokina 12-24/4
Canon 50/1.8
Canon 70-200/2.8 IS
Canon 100-400/4.5-5.6 IS
Leica M6 TTL
2 tiny lenses
15" ThinkPad
Other bits and pieces
I have been having a hard time deciding whether I actually want to take all this stuff over. I'll probably be leaving the 100-400 behind, but it might be nice to take the 70-200 just so I have some sort of tele option available. I'll be staying with relatives, so leaving some or all of the gear at the house during the daytime will not be a problem. I'm not going to be lugging everything around with me wherever I go. I will probably take a separate smaller bag in my checked luggage to transfer items to for daily shooting.
I'm also undecided on the laptop -- they are living in the stone age and have no computer or internet, but I would like to be able to copy and edit/review photos while I'm there. Taking the laptop would also make dealing with storage much less of an issue (I only have one 4GB CF card). I have no idea how I would get the laptop over there if I didn't have a large laptop/camera bag. I think the only option would be to put all my photo gear in a big laptop case.
Someone suggested the Tamrac Adventure 9, which seems absolutely ideal. Unfortunately, it appears to be slightly larger than either the Heathrow or Air Canada carry-on restrictions:
Adventure 9: 20 x 13 x 11
Air Canada: 21.5 x 15.5 x 9
Heathrow: 22 x 17 x 10
Are the outer dimensions of the bag flexible at all? Could I squash it 2" to fit the Air Canada restriction? Can anyone suggest a different bag? Any thoughts on which gear I should take with me?
Thanks
