I've been to Africa 17 times and preparing for 18th.. I'd like to share my thoughts and what I noticed during those rips.
In the small planes rather the size is important than the weight. I even don't remember if they ever checked the weight in Botswana .... South African Airlink checked once and we paid for the over-weight. The size could be a problem but I think, they can always send your additional luggage with a next plane.
I've ben to a few photographic safaris with South Arican photographers (Wim van den Hiever, Brendon Cremer, ec..) and they had two bodies with two lenses: 400/2.8 and 70-200/2..8. Sometimes wideangle lens. Not more.
The problem is that if you have three bodies and many lenses then it is
1.) difficult to put it in the game-drive vehicle
2.) difficult to quickly get them out and start to shoot (without dropping something from your bag or the whole bag)
3.) difficult
to decide quickly what camera+lens to choose for a particular scene!
So, you really need to think over what you want to shoot in that particular location you stay in. Are there nice landscapes? Do you like to shoot landscapes? Is there a hide? Will you shoot nightscapes? Will you shoot birds? Is it a private game reserve or National Park?
1. If it is a National Park then you need 800mm or 600mm because your guide will not go off-road. You take your pictures when the light is OK., don't need fast lens perhaps. The Park will close when it will be dark.
2. If it is a private game reserve you will make night drives and you will need perhaps a flash and fast lens. You don't need long lens if you don't shoot birds. In private game reserves the guides come close to animals and with long prime you can have a problem especially if in your game-drive vehicle all other guests using smartphones ;-) you will need to persuade them all to drive away from the animal so that you can take a shot.
3. It is important if it is a photographic safaris or not. If yes then the guests will have long lenses, if not then probably they will have universal zooms, consumer lenses and even smartphones ;-) They will want to drive closer to the animal.
4. If you have less gear - you have more creativity and freedom. You are doing the best from what you have and use your gear in a very productive way. You will not miss your shot. The light gear has an advantage!
I noticed that I definitely need at least one fast lens like 70-200/2.8 for twilight and low light scenes, for bigger animals and if there is some action (lions huning buffalos) and you need to take a whole scene (with 500-600mm it will be difficult to keep running cheetah in the frame! but I don't say it is impossible ;-)
Keep also in mind that you can shoot video when the light is gone. For video you need to follow 180-shutter rule. That means you shoot 1/60sec by 30frames per second. and if stills will be unsharp by that shutter speed the video footage will bear all that unsharpness.
5. So, if it is dark - switch to video.
I recommend to shoot more video on safari. in general Especially the moments in the camp, your coffee breaks and sundowners, your travel companions, your guides, etc You will be happy to have a look at it later and refresh your memories. If you have iPhone 15 max pro or other phone take it always with you, even to the toilet! Becasue you never know what is waiting for you there. Never go for lunch, dinner, breakfast without your camera or phone. It is a rule. Don't break it. I did and I regretted it a LOT. Twice I missed a leopard when driving in the car and my cameras were in the backpack! The time I got the gear out the leopard was gone! Once during the breakfast the pride of 14 lions came, during the dinner elephants, hyenas, lions... So, believe me, follow that rule!
You can get a lot of useful information on safaritalk.net Forum about safaris and last news.
For example, for me, as self-driver, it was importnat to know that Ethiopian Airlines flying directly to Maun starting from June 2024. So, I don't need to have a connection flight anymore when travelling to Botswana and can take over my vehicle directly in Maun. Alerady bought a ticket
Cloud Nine Restricted return-ticket is 2334€ (kind of busines) from Europe and I can take 64kg of luggage and 16kg of hand-luggage
I think, it is a good price for an almost direct flight! You can buy it for Star-Allianz miles as well. So, highly recommended.
Sometimes, we combine self-driving and flying into Delta and in this case we let our luggage in the Tour Operator Offcie in the Maun airport.
