While it looks out of favor, another possible source of lens damage is 
plain, old fireworks.


Even if one's in a zone apparently safe, sudden gusts of wind may land 
more than smoke in lens, eyes or clothing. While the damage presented to 
the lens on the link is rather extreme, even smaller coating damages may 
degrade quality and are easily prevented by a lens filter.


I'd add a lens shade myself - they cut down filter/ front element dirt 
and saltspray for those near the sea, cut down flare, and protect filter 
threads from dings in case something bigger than sparks hit the lens.


...of course if it's big and fast enough there are other issues than 
gear damage.

I use a piece of plywood over my lens for this stuff.

If that's not handy I use duct tape.

Use a UV filter when playing with steel wool

2012-02-16 Thread Bipin Gupta
Why protect only the lens element, when hot molten steel lumps from
steel wool as in this case, quoted and pictured, can hit any part of
the camera causing damage.
This silly fad can also hit and injure people. It is taking
photography to silly and foolish heights, I am afraid.

If you're gonna play at pyromaniac, you've got to be on the ball.  If 
you're gonna do more than play, hire a fire squad, 'cause you're gonna 
need it, eventually.

It's amazing the number of people who don't seem to realise that the
14-24mm isn't like their kit lens.

Think of what it will do to your modern plastic lens' body.  With or 
without a UV filter.
