I have a Voigtlander Vito CLR, and would be likely to take that to India were it me going (along with my OM-1). It looks 'old' and is less likely to be 'lost'. I would also take the Zeiss, another old looking camera which will give superb results and is small enough to fit in your hand luggage.

I have friends who visit India regularly (they have a bar in Goa). They say that theft is not a problem, the main problem is begging. It seems harsh but the best thing you can do is tell beggars a firm 'No.' If you don't you'll be swamped by them. They are mostly children working for adults, so don't feel bad by saying no.
