Street photography lens

[Jo3y3oy]

Could any one help me please. I have a samsung nx200. So far I have a 20-50mm lens and a 16mm ultra wife angle lens. I'm looking for a good lens for street photography and a general walk around lens

I need it for my travelling trip to Thailand


Many thanks

What's wrong with what you already have?
