Looking for a travel lens for our upcoming vacation to Africa. Of course the 70-200/F2.8 IS would be the best, but I had that and sold it because I found it way too heavy for the times I can use it. So more looking into on of the all-in-one lenses. Currently more of less considering the Sigma 18-250mm/3.5-6.3 DC Macro OS HSM Canon
Any advice? Gear in sig.
