Hi. I am going to be moving to Africa soon (indefinitely) for work and I have some equipment decisions I need some help with. I currently own a Canon 5d with only 1 lens, a 50 1.4. I have found this combination to give me very good results. I do mostly street photography, documentary photography, and portraits. However, I would like to expand my lens collection to get the best images possible. Would there be any lenses which may be better than the 50 for my kind of photography? A zoom would probably be a good option, but the reports I read about the 24-70 and 24-105 are very mediocre (and there seems to be a huge hassle getting a "good" copy).
I'm even wondering if having a 5d is the right camera over there given it's lack of weather sealing and lack of a sensor cleaning function. I've thought about the new Mark III but wonder if I will lose image quality. I've also thought about the 1Ds and (blasphamy) the Nikon D2x. I've also been thinging of a rangefinder (M8) or even going back to film (would this be much harder to do in Botswana?)
Any help would be greatly appreciated!
Thanks,
Jmbern
