To follow suit on that thread : Santa gave me the Timbuk2 bag after all
The Small version, which is actually large enough to hold the K20D with Sigma 17-70 mounted, the 60-250, DA21, F50 f1,7, DFA 100 macro WR, a Sigma 530 flash, and a few odds and ends. It's extremely well made, sturdy fabric, loops for a tripod, comfortable strap, room for a laptop or tablet (though not much padding there). The camera section is an insert that is very well made and easy to remove if needed. Its all I wanted.
It looks great too, but more of a "sports" bag than a classy leather one. And it clearly does not scream "camera bag".
