I think the front lens element(s) also bought it in that incident. The lens as a whole no longer seemed to be forming an image anywhere near the camera's sensor after the impact. The wrecked piece of glass looks kind of thick for a filter, anyway.
A filter thick enough to protect against an impact that would qualify as an 'optical element' in its own right and would have to be compensated for in the rest of the lens design process, especially if it's a wide-angle lens or a zoom that can go wide. (BTW, I am an optical designer. So, yes, this is definitely within the boundaries of 'If he didn't know it, he'd be taking pay under false pretenses'.)
I keep filters on all the lenses I have that will take them to protect the front elements from lesser impacts and from getting dust/dirt on them. Cleaning lenses badly probably ruins more lenses than impact damage does. In any event, I'm not expecting my filters to stop baseballs.
The lenses that won't are pretty worrisome because the reason they won't is generally that they're fisheyes or very wide rectilinear lenses whose front elements bulge out past the front of the metalwork-- so they combine extra vulnerability with not being protectable.
Any place with a "tubing hill" generally looks about like that (though usually with inflatable tubes, not little sleds like that). I've seen them in the middle of nowhere in the Colorado mountains (Snow Mountain YMCA Ranch - https://snowmountainranch.org/activities/summer-tubing-hill/), in Park City (as WiscoDave noted above), and even in a k-drama, so they've got 'em in South Korea too....
#9 was expensive....
ReplyDeleteMight be the filter. They're sacrificial. Sort of.

#4 gets 10 points deducted off his CCP social credit score. 10 more and he he forfeits a kidney.
ReplyDelete#7 happened to me 2 months ago. The cops DID get him...
ReplyDeleteI’m digging #10. Reminds me of flying in an OH-6 with a Nam vet. Damn I was a brand new 2LT, fresh out of OCS.
ReplyDeleteSaber 7
What manner of flying machine is #10?
ReplyDeleteHelicopter.
DeleteMy guess would be a '47 Packard...
