Before the Great American Eclipse swept across the United States last month, there were plenty of tutorials showing how you should photograph an eclipse. There were even warnings about pointing your camera directly at the sun, and how it could result in damage to your equipment.
Those warnings clearly didn't make a big enough impression. Some eclipse chasers were dead set on pointing their camera at the sun no matter what you said, Dad. Of course this happened. Some people didn't even heed advice about not staring at the sun with their own eyes.
To prove some people simply didn't believe the warnings, camera equipment rental company LensRentals shared images of rental equipment damaged by flippant eclipse photographers. A quick look at the partially disassembled Canon lens above shows the damage caused was less than subtle.
The most frequently seen issue was damage to sensors and shutter systems. However, name an internal part and there's probably a picture of it damaged by the sun. There were damaged mirrors, lens irises, and filters, among other components. (When you're prepping to take pictures of the 2024 total solar eclipse, make sure you get a solar filter. That would have prevented this kind of damage.)
