Is missing. The 40mm pancake. I have a 5d2. When not crowded, I use my 24-105. But sometimes in busy cities, like Rome or Istanbul, I leave the lens in a backpack and walk around with the 40. I have gone as far as putting electrical tape on the logos. I am a big guy and it looks like a large point and shoot.

I was mugged once in Rome and my 5d2 stolen. So it is not paranoia. It was a train station (Trastevere, I think) and I had to change trains. Someone threw water and flour on me. I thought I was careful to find a quiet spot and they picked my backup and ran.
