Well. I had bad experiences with my cameras overseas too.
Once (4 years back), my Nikon F65 was stolen from my backpack in Italy. Was in the train cabin with my friends. Then in the middle of the night, this group of punks came into the cabin.. and i subconsciously saw them but somehow had no strength to wake up to see what they were doing. After that, i heard of the notorious Italy trains where they will smoke us out and rob our stuff... guess i kenna that...
So, i bought a new camera with dual lens. And when boarding the bus, my longer lens was pickpocketed. The pickpocket was really skilful in that he actually went into my bag to steal without me knowing. When i feel somebody's hand in my bag and turn around, the pickpocket disappeared into the crowd and so did my lens. Luckily, he only took the long lens and not the body.. if not, i will need to get a new body again.. From this incident, i learnt to use bags with velcro and those that are not so easily opened. Also, i carried my camera bags in front of me nowadays, not even at the side anymore.
My friend got his pns camera pickpocketed during our trip to Mongolia 2 years ago. The camera was in his front jacket pocket, securely zipped up. Yet, in the crowd, the pickpocket was able to unzip his pocket, put his hand in and stole the camera. Luckily, we are able to claim insurance for that... Previous 2 cases, i didnt buy any insurance..
But, recently i havent met with any such cases. Probably cos i am more alert nowadays and even bring a tripod whereever i go?
