My walk-around kit changes all the time, but centres around what I can carry in an old Sony compact shoulder case. It was designed for my first digital camera, which had a fairly small body but a humungous Zeiss superzoom out the front on a pivoting mount. The case is well padded, looks pretty sharp, measures about 8"x6"x4", weighs next to nothing, is comfortable to carry even while running and is pretty much weather proof.
At the moment it has my K-5 IIs with DA21 mounted (my single in July challenge lens) and FA43/FA77 piggybacked on an Op/Tec double rear cap. The pockets on the sides have room for a filter or two and a spare battery if I feel really keen.
If I pack the K-01 instead, the bag can also accommodate four limited lenses on two Op/Tec rear caps.
Alternately, it will hold my Q10 with all four lenses and a battery charger if I'm that way inclined.
If I want to go WR I can keep the K-5 and DA*16-50 around my neck, and use the case for either the DA*50-135, or the DA*55 and DFA100WR doubled up.
If the case is not big enough it is no longer a walk-around.
