Long Trip in South America!_Lens for NEX6 & Back up Camera?

I agree with DirkD as far as the 16/2.8 with wide angle adapter is concerned. In 3 months you will surely end up in many towns and villages and in the older parts the streets are narrow and a WA lense will be needed. A small package like the NEX and 16mm lense are very low key and fits in your pocket.
