If I sent them to Lausaunne from here in HKG, the wait averaged about 4 weeks. One of my friends in London had the worst Kodachrome experience I've heard of. He sent in a whole bunch of them to Wimbledon in February after his trip to Sharjah. The last time I heard, he's still waiting for them!!
I also have a copy of the Sony DSC-F505V. While shots of aircraft on the ground is OK with this camera, it is just not responsive enough to shoot aircraft in-flight. After quite a bit of disappointing experiences, I now designate this camera for general photography only. For aviation photos, it's either sticking with celluloid or coughing up the dough for a pro-level digital SLR.
