Recently LensRentals, a photography equipment loan company, took over a camera Fujifilm GFX100 with a sale price of up to 10,000 USD broken from a customer. He said that he used a camera with a waterproof case to take pictures and cameras into the sea “Suddenly broken for no reason”.
It is true that from the outside, we do not see any sign of water intake, but when the camera was removed, LensRentals figured out the cause: the machine was corroded by sea salt. According to Roger Cicala, founder of LensRentals: “Just remove 4-8 screws on the tripod mount, you can see signs of corrosion. Water can stick to metal for a long time, ‘creeping’ deep into electronics without you. not know “.
“It is very difficult to repair a camera with salt water intrusion, because when you replace a corroded part it can still fail within a few months. It is the harm of getting into the water, looking On the outside there is no sign but the internal components are badly damaged. “
He also said that the camera was damaged because only a little bit of seawater penetrated, but the whole machine was not submerged in water for a long time (because the user used a waterproof case). The Fujifilm GFX100 itself is mildly water resistant and can also be used in the rain, but the company is not talking about sea salt water resistance, which is much more corrosive than fresh water.
This is probably a very expensive lesson for photographers as well as other equipment users in general, avoid using electronics in salt water if you do not want internal components to corrode. to the point that it cannot be repaired.
