NASA just ordered 11 new Nikon D3 bodies as well as several 14-24mm f2.8 lenses. The new gear will be used to document the daily life within the program and on the space station. They join the D2x bodies and a plethora of Nikkor lenses and accessories already in use.
Since I primarily use D3 and D2x bodies with a lineup of all Nikkor lenses, I think I’m in good shape.
