I and my wife will be visiting Buenos Aires as a part of our South America trip. Since I am a keen amateur photographer taking photos will be very important aspect of our trip.
I just wonder how safe it would be to take photos with a fairly big DSLR camera with 15 centimeters long lens around the city during a daytime and perhaps around and a bit after sunset.
I am not afraid too much from common pickpockets, but concerned more about mugging under a knife or a gun point. The camera would be kept in a regular backpack, but still I would need to take it out while shooting photos.
In case this is not a good idea I can think of two possible options to reduce the chances of getting mugged:
1. Take the double decked hop-on hop-off tourist bus and shoot from the top deck without getting off the bus at all.
2. Hire a private guide for tours around BA, I would assume that it will be safer to take photos with a DSLR with a local guide.
We will be staying right in the center of the city on 9 de Julio Avenue, opposite the obelisk.
Thank you in advance for your opinions, any thoughts and ideas would be greatly appreciated!
