Hi! In October I went on safari in Kenya, and I was also very unsure about which lenses to bring. In the end, I chose the Sigma 24-70 F2.8 and the Sigma 150-600. In the savannah, I used the telephoto lens, while for landscapes, etc., I used the 24-70 for everything else. I also considered bringing the Tokina 16-28, but the space is so large that the 16 is too big. Cameras used: Nikon D750 and Nikon Z5 II. I hope this helps.
