Hand luggage camera bag

With all the travelling done by folks on here I imagine this issue has come up for a few of you. Can anyone suggest a combined 'camera gear/stuff-which-isn't-camera-gear' bag which fits within airport hand luggage restrictions? It'd need to hold my K20D with a Sigma 10-20, DA35 Limited, and another lens (either a DA18-135, or the 50 and 100 Macros*). Essentially what I'm looking for is a bag which has camera inserts, but also has an undivided chasm for the other stuff I'm likely to want with me.

Also, I'm going to a city so I want a shoulder bag rather than a backpack.

Cheers

My Tamrac Expedition 5 backpack is just carry-on legal and goes as carry-on always. If they decide to weigh it may give a problem where weight restrictions apply, but it's never been weighed.
It also holds my netbook, though it's not designed for that.

Think Tank do a range of carry-on legal bags, but so do most manufacturers nowadays.

A good choice!

The Lowepro Classified series is nice. Lots of space and looks and works like a Gladstone bag. I use the 250aw.

Another vote for the Lowepro Classified, I have a 200 AW & it travels well on the plane, I get all my gear in my sig & a laptop in it along with a few travel bit & pieces...

Those do look quite good, and also don't scream "camera bag". I'm acquainted with the quality of Lowepro's bags (have one of their Stealth Reporters as my "carry everything" bag) so no concerns in that regard either.

Billingham 335. Never had any problems at airports with it. And can get loads of non-camera stuff in the various pockets and non-padded parts.

I fly often to Spain and take a Think Tank bag, which is great.

I have a Think Tank bag and its good and does not really look like a camera bag
