We are just coming off a very busy crazy period at work, so my wife and I have decided we need to get away for a couple of weeks to "recharge the batteries", so to speak. For us, this means heading off to some remote part of the world for a couple of weeks, with our cameras and a fairly limited amount of gear (it isn't a luxury trip so transportation and accomodation will be fairly basic). We are limiting ourselves to a large duffle bag for clothes and a camera backpack each. We leave in less than 3 weeks (off to the travel medicine clinic on Monday).
This time we are heading off to Ethiopia and will be heading into the southern part of the country (i.e. south of Addis Ababa) down towards the border with Kenya. Of interest is that we will be getting into the areas where the Ari, Karo, Murse, Hamer and Dassanech people live, so we are hoping for some good people shots. I expect the days will be sunny and much of the shooting will be your typical travel photography; i.e. highly opportunistic and during periods where we will be fighting with the lighting.
I'm thinking of taking the D800 (D90 as backup) and just going with the f/2.8 24-70mm, the f/2.8 70-200mm. I'll have a few filters and the tripod along as well. I'm also going to want to take the SB900 for fill lighting, and this is where I am wondering if I need to pick up something like a Lastolite Ezybox as a modifier. The last time I shot in similar conditions, I found that using the on-camera flash was not giving me the quality of light I was looking for.
Any other thoughts on equipment that I might consider taking.
