In next winter vacation, I'll be heading to Tanzania (Tarangire, Lake Manyara, Ngorongoro, Oldupairotko and Serengeti) and afterwards for couple days in Sansibar.
Since this is going to be once in lifetime kind of trip for me, I've already started to ponder ideal photography set for the trip. I will take 20D and 40D as camera bodies with me and 17-40/4L USM as a lens for landscape photography, but I am having hardtime on figuring, what to do with tele part on a trip ...
One option would be to use existing set of 70-200/4L non-IS on 20D and 300/4L IS with 1.4x II on 40D. The other option would involve selling 70-200/4L, 200/2.8L II, and with some additional funding, buy 100-400/4L IS, which seems to be everyones favorite as one lens solution for safaris.
I guess my main questions on comparing these two options is whether or not its worth an effort to take landscape shots during game drives (need for having 17-40/4L on one body) or would 70-200/4L on 20D and 300/4L IS + 1.4x II on 40D cover all bases?
Another question is also whether it makes sense to takes tripod for times in camp or would it make more sense to leave tripod at home and use beanbag whenever you need support for a camera?
Regarding buy&sell stuff... 70-200/4L is probably going to be sold at somepoint, it is just question of whether it happens before or after this trip.
If I buy 100-400L, it would overlap with 100mm macro and 300mm lenses and as such its quite likely that either 100-400L or 300/4L IS (and 1.4x and 2x) gets sold after the trip.
