So far NASA used Nikon because Nikon didn't use fluorite elements, unlike Canon. However now Nikon started to use fluorite elements as well. I wonder what will happen in the future.
- dpark 8y agoWhy would they avoid fluorite elements?
- blattimwind 8y agoFluorite glass is more sensitive to shock and vibration compared to regular optical glasses. Iirc some people actually managed to disintegrate lens elements here on earth, without even hurling them into space.
- dpark 8y agoI guess that makes sense but is NASA actually shipping off the shelf DSLR lenses to space anyway? I guess for astronauts’ personal devices, whatever. But for actual scientific instruments, I’d expect NASA is bidding out custom contracts that can easily specify how much shock tolerance the cameras must withstand.
