There's a blog post about the topic at LensRentals:

 

https://www.lensrent...clipse-of-2017/

 

While there's a quite a large diversity of the kind of damages (always burns, but in different parts of the equipment), they say they were impressed that the number of incidents was low, after all.

Most of it Canon equipment - which might be a coincidence or a hint how widespread Canon is. That's the downside of making (usually) reliable equipment to use in tough conditions - cutomers tend to switch off thinking carefully. But honestly: who of us would have thought aperture blades could melt? Although it's logical that they are no longer made of metal (and even metal melts...)

    No longer made of metal?

 

        When did that happen?    My God we now have plastic easy melt diaphragm blades...on a Canon 600mm F4 expensive monster.....is nothing sacred?

no idea, but metal foils in the range of few 1/100 mm also don't resist long if you focus a very hot light beam on them. The sun-shots into the sensors were also pretty impressive.

Switching to mirrorless I'm even more careful, because with the mirror I was primarily worried about my eyes; now that my eyes are safe, there's the risk that I forget about the equipment. I do shoot into the sun, but always mentally counting a timeout before giving up. Of course I'm talking about generic photography with the sun in the frame, and not eclipse or sun-focused (no pun intended) photos...

 

Did you note the final statement about the fact that insurance doesn't cover this kind of damage? A few people will long remember this eclipse...

And did you also read the statement that a there were given instructions and saftey advices? I think ALL the people remembering  this eclipse for a while, are allergic to manuals  :huh: And allergies are always expensive...

Yes. I read it. Once in a while, it's a reasonable position for an insurance company. BTW, even if one doesn't read the fucking manual, there's plenty of advice on the web about how to deal with eclipses...

Yes, but one needs to see the possibility "I'm maybe not Mr. Know-it-all, so I better get myself informed"

 

And it was not the insurance which created safety warnings, it was LensRentals and they put some effort into it. Without that, I'm sure it could have been worse, but when you see POTUS  watching the eclipse without any protection, it says something about the mentality. "If I get hurt I gonna sue the sun and become richt"

I don't believe POTUS actually watched the eclipse without any protection. In fact, either he should have suffered from a severe eye problem (it's also not young), and we would have been informed, or he is Superman and can look into the sun. I think he was photographed looking up and the newspapers did the rest.

 

PS Just to play in the open :P : I'd have wished for a much better POTUS, but I consider Trump the lesser evil, by far.

Weird to state that Trump is the lesser of two evils. I wonder what the other evil is? Yeah,I agree if the other evil is Putin.

JoJu, I wrote a well defined point: if he watched at the sun, either he got a medical problem, or he's Superman. Clearly it's not the latter. I don't see reports about the former fact. So I conclude he didn't get a medical problem, thus he didn't look directly at the sun. It doesn't need to add that one can quote one million newspapers, each one reproducing the same photo, which doesn't proof anything, we only have a million reproductions of photos that don't proof anything. I could as well shoot at myself with the same pose and state that I looked into the sun for ten seconds, and I'm Superman.

One can easily look directly at the sun and suffer no consequences, for a short period of time. But it always bears a risk. Looking at it for seconds or longer is not a great idea. The idiot Trump indeed did look several times at the sun starting to hide behind the moon, even after people kept telling him not to.

The problem is that the damage is not instant unless you look at the sun for a period. 10 to 15 seconds would likely cause long term damage but not necessary instant damage. As you can tell if Trump can't 'see it' it didn't happen. He has no sense of science or cause and effect; esp if the effect takes years to materialize. 

-

He has got to be one of the worse person to be president (of usa) esp during a period where actions have a global impact that can take or last years. Unfortunately he has installed an administration (including a vice president) that is as bad or worse than himself so I guess it is going to be a very rough ride for the next 3 1/2 years (even if he is impeached/removed before his term expires).

-

I hope not too many  aperture blades are plastic but I guess some of them probably are - at least according to lens-rental article.
