International Space Station
[edit]
In December 2016, Japan's national aero-space agency, JAXA, installed a Sony α7S II outside the International Space Station's KIBO Japanese Experiment Module after determining it would be durable enough to withstand the vacuum of outer space.[8] According to Sony, the a7S II captured the first 4K footage in space using a commercial level camera.[9] In order to mitigate the temperature extremes of outer space, the camera mount is equipped with a heater and radiator.[10] Sony stated that the camera body was not modified but the software was modified to include the ability for full remote control from inside the Space Station.[10][11] JAXA selected the Sony FE PZ 28-135mm F4 G OSS lens to capture images and record video for the purpose of this assignment.[12]
