How to get hundreds of out-of-focus photos in Africa?

Take equipment you aren't familar with and click away,

If you are going just to shoot photos - DON'T! The results you will get with even the greatest, most expensive telephoto lenses in the world won't get you photos that are in focus and even just interesting. Photography, with long telephoto lens, is a speciality that requires understanding the capabilty of the lenses & the techniques needed to achieve at least "good" focus results.

Any responses that actually talk about equipment choices are like making suggestions to someone who hunts rabbits with a single shot JC HIggins shotgun and asks "will 3" 20ga slugs be OK for elephant or should I borrow a friend's 12ga slugs?"
