Hello, lens help

[byron87]

Hi there, I just ordered a Canon 5D Mkiii with the 24-70mm lens....

Ive been doing a bit of research over the net as to which other lenses i should purchase?

Im going travelling around the world around may this year, and would like a good set of lenses and gear to keep me happy.

I enjoy all types of photography but have mainly focused on landscape, sunrise/ sunsets, macro and astrophotography...

Any help would be greatly appreciated!

Thanks heaps.
