Agree with the above about security. The good thing about Italy is that it is a tourist destination and given the number of tourists, the rate of crime is very low. While it is a concern, I wouldn't worry too much about it. In the places you're likely to visit, you'd look out of place if you didn't have a camera. And Italian's are very image conscious - members of the opposite will be very impressed that you have a shiny new 5Diii. Just use some common sense, keep your eye on everything and try not to leave your gear unattended at a cafe, on the street etc. If you're going to lose something, it will be because you've given an opportunistic thief the chance to grab it. Although, with the influx of refugees using it as the gateway into Europe and general economic downturn, maybe things are a changin'.
