Originally posted by pathdoc Minimise your kit. K-3, 18-55, 55-300 (take the 55-200 if the 55-300 is not the WR version). A fast fifty. Small tripod. ND and polarisers as appropriate to the lenses. The smallest bag all this will fit in comfortably.
Consider the DA15 for sweeping-vistas shots.
Check the weather.
@photoptimist has offered good advice.
I am no expert but for what it is worth, here are my thoughts
I have to respectfully disagree, take 2 camera bodies,
I'm a firm believer in Murphy's Law: anything that can go wrong will go wrong and Finnegan's corollary to it: Murphy was an optimist
have one set up for long distance, one set up for in close action
are you going to be in a vehicle? I used a K 5 II + tamron 70 - 300 mm zoom for the most part and had a Nikon Coolpix p610 as back up for our Northern Safari Circuit in Tanzania last year
most shots were from top of vehicle on bean bags with engine off.
try to find out how close the animals will be. we had them from up at the vehicle to too far away choose your lenses accordingly
take multiple chargers/batteries and a battery grip that will take AA batteries. K 3 has one.
have fun, take "photos" first with your mark 1 eyeballs and store in the brain, than try to capture images on memory cards
don't forget to look in all directions
