Going Zambia over Easter, and been trying to work out what to take.

I don't want to bulk myself up with gear, and don't want to take my primary work lens out with me - 24-105L

I want flexibility but also without carrying to much, I could take my 5D out without the Grip and take my 50mm Prime...but would also need something wide?

I have thought about getting a G15 camera, can get one for £300.


So, thoughts? Opinions? Ideas?
