Sure both break sometimes, so do condoms - do you suggest people not use those for protection either?
... I imagine it is hard to break the front element of many lenses, but they are easy to scratch (I've done that too)... I'd rather scratch a filter and replace it than scratch the front element and drop the value of the lens. Lenses for me come and go, and it is important to me that they hold their value, so that when it's time to sell one and try something else I haven't significantly devalued the lens.
Quote: Every lens needs a hood to reduce flare, improve contrast and protect the lens. With a solid lens hood you do not need a filter. If you are not using a hood, you are not following best practice.
Hoods do not protect the front element from rocks, branches, etc. while hiking / climbing. Hoods (reversed for storage) do not protect the lens from rubbing on the lens cap and / or potentially gritty fabric inside my pack in the event that the lens cap comes off in my bag (a common occurance it seems - perhaps I need caps which screw in to the filter threads).
Quote: I have taken my lenses into salt sprays, under Niagara Falls (fresh water but lots of it!) etc. If I had a filter, that would only increase the likelihood of bad internal reflections off all the water vapour and droplets. It's not so hard to clean the salt off the lens afterwards.
Ah, but I'd rather clean it off a filter than the front element. I believe the whole "bad internal reflections" to be a myth, or maybe a result of non multi-coated filters - I've shot misty waterfalls, lightning, sunsets, rainbows, shots with the sun in the frame, water drops on plants, wildlife, and more with UV filters in place without seeing the effects of filters. I
have seen internal reflections caused by bright point sources (x-mass lights) in a dark room, and I didn't reshoot without the filter to confirm whether that was the cause or not - I'd be willing to believe that the filter contributed in that case, but I don't know for sure.
Quote: Vendors laugh to the bank when someone spends $150 on a piece of glass worth ten bucks. Filters have the single largest markup of any piece of photographic equipment. And most do nothing except put another layer between you and what you want to capture. It's a mug's game. Not spending that amount? Then you are buying bad filters that will seize or cause image degradation for sure.
$150??? I can get B+W MRC 77mm protection filter
for around $60 (of if you don't trust buying from HK, pay $85
from B&H). I don't actually have this B+W, mostly I use Hoya, but I don't know of a more expensive brand than B+W, so I used it as an example... Sure I could pay $150 for that filter, but that would be daft... If vendors are making money in this area, I bet their shareholders are happy.
Quote: Do pros put a UV filter in front of all their lenses? No, the vast majority certainly do not. Whenever this question comes up on professional forums all you hear is the sound of massed scoffing.
Well I've already quoted and cited one pro who does.
From Marc L's workshop information site, you can see that he recommends them as optional equipment for protection...

I've never been on a "professional forum" since I shoot Pentax

Quote: Save the money on four or five filters and you can replace a lens if and when it breaks. Or, if you are truly motivated by fear, buy insurance.
I actually intend to buy insurance, since I do often carry a lot of photography equipment around in the back of the helicopter fuel truck, while it bounces down dirt roads in the wilds of Nevada. I would like to be covered if someone drops my pack, or it gets stolen (or I drop a lens in a manner which the filter doesn't protect
)... Thanks for reminding me to talk to the insurance co. BTW, I do have health insurance, should I stop wearing my helmet when I ski or mountain bike?
