One of the most exhausting situations photographers face is changing lenses, particularly in the field. It's essential to find a secure spot to place the detached lens and ensure it doesn't get dirty. In the weightlessness of the ISS, Pettit avoids these issues by simply placing another lens in front of him.
Nikon representatives commented on Pettit's video, saying, "Don't try this at home."
Another commentator joked, "How often, while on Earth, do you accidentally drop a lens, expecting it to float in zero gravity?"
