Going in August with family (wife and 2 teenage kids) on our first- and likely only- African Safari. We will be spending two weeks total, mostly in Tanzania with a private driver/guide then a few days in Kenya (Mara) with a small group in an open sided vehicle. I will have my 5D and 7D bodies with me.
I was planning to rent a 500mm f/4 for the trip as I really want the sharpness/image quality of my 300mm f/2.8 but with more reach. Reading the safari threads here I have started wondering though. Most are recommending the 100-400 (or 200-400 if it ships in time).
So now I am wondering if I should just bring my 300 f/2.8 and extenders for the 7D, and keep my 70-200 f/2.8 on the 5D and work with what I already have? I will still bring some wide lenses for landscape shots of course. The 300mm and 5D have spoiled me for image quality now so really want the best possible lens for the trip.
I have no problem lugging around heavy lenses. I hiked around the Galapagos islands a couple years ago with my 300 f/2.8 slung on my shoulder the whole time and didn't regret that decision for a second!
I appreciate any advice from those that have been.
