very good video to discuss this topic
thanks a lot

By the same token it is almost certainly true that if the filter threads get damaged by impact it will also damage the lens threads. IOW, there is virtually no protection at all offered to the lens threads.

If folks want to see the results of some very good tests, check out a video by UHH member Steve Perry. Steve does a lot of very good videos, and this particular one is excellent.

“Based on what I’ve seen in these tests, I really believe that
the vast majority of people who have broken UV filters have
simply broken their UV filters and really didn’t save their lens
at all. I believe that in most cases, the filter didn’t do anything
to save their lens from cracking or breakage — the UV filter
simply broke because they’re much more prone to breakage
than the lens itself is.”

Wives really appreciate being reminded what they should be doing. I like your comment about containing yourself "as much as possible."

Yes, filters do protect lenses. I have them on all of mine. We had a similar post two days ago (but not about the wife). Like you, I cringe when I see people hand-holding a camera with no straps.

I was just about to post this video.

In terms of protection, I like filters for protecting the glass element from abrasion, scratches, and pokes. With the Xume magnetic adapter, I can have the filters on and off in less than a second. If the lens were to fall and hit the ground with that mag adapter, I suspect it would just pop off.

I say let the Supreme Court decide this issue, they are never wrong.

Exactly. Finger prints, scratches, sand, saltwater... all things that might cause damage that a filter could prevent.

Damage from dropping, either to the front element or to the filter threads is not something a filter is likely to help with.

Actually, it's my wife's experience.

We just had a week vacation in the Canadian Rockies (Calgary, Canmore, Banff, Jasper, and many lakes, waterfalls, wildlife, etc.)€“ had a great time. There were hundreds of tourists from many nations everywhere we went and I couldn't believe how many carried their DSLRs without using the strap (I use the Op/Tech Custom Strap Pro with X-Long extensions and Uni-Loop connectors which allows me to sling the strap/camera across my body and have no neck or shoulder discomfort). And, I couldn't believe how many times I had to remind my wife to use her strap (she didn't appreciate my reminders but I recently upgraded her Canon SX30 to a Nikon P900).

I know that digital camera sensors eliminate UV light so that UV filters are superfluous. But having several from my film camera lenses, I use them as protection instead of buying new clear filters. I'd much rather clean a filter several times a day than my lens, and in Canada we both needed to clean our filters constantly (I mostly used a CPL filter on my wide angle lens and a UV filter on my telephoto lens; I took only two lenses with me). Well, on the last day at night as we entered our room to pack up, my wife dropped her camera on a very hard floor (again she was hand holding without the strap on). I contained myself as much as possible. Fortunately, the UV filter that I gave her was on the camera – it shattered (don't know what it hit) but there are no dings or scratches on the camera or lens glass and the camera works fine.

I have taken many test shots with and without a UV filter, with all of my cameras, and cannot tell the difference. I'€™ll replace her filter with a clear glass quality filter. For us, the protective filters will remain on. Hopefully, lesson learned about the strap!

I would still use a Haze filter, it cuts the blue haze in the distance in far off shots. like the Tiffen Haze 2.

No lens cap?

Hood?

Exactly. Defies logic and the laws of physics. It's like saying helmets are useless. Guess that's why NASCAR drivers, football and baseball players, to name a few, insist on wearing them. How long will we be confronted with this lunacy?

You have no way of knowing this. In this case it may have protected the lens, it may not. The point is that there are some cases where a filter does protect a lens; not always, that is true, but there are times that it will save a lens on a drop or a bang. For that reason alone, there no reason not to use one (I'm talking a good quality one, not the bottom of a coke bottle like Kodak used to put on the instamatics). I'm sorry, but knowing this fact, why would anyone not use one; it makes no sense. Then add to the mix, the many times a filter saves the front element from getting a cleaning. It's a fact every time you clean the front element, you are possibly slowly removing the valued expensive coatings you paid so much for and weather you see them or not, you are slowly putting scratches on them too. It's a no brainer to an intelligent person; and the only time filters have been to shown to possibly cause an issue is when a direct light source is in the the photo and it may add to the flaring in the lens. If that is an issue for one, what does it take to remove it and put it back on after the shot. To keep arguing the issue is insanity. The fact is the filter protects the lens in more than one way.

Insanity: to keep doing the same thing repeatedly and expecting a different result.

That's done more efficiently in software these days.

Sorry, I thought you had a real, authoritative source, not a guy working out of his garage with a pretty website.

Just my three cents:
I use a clear filter when transporting a lens. Once I get to my shooting location I remove the filter and proceed with my shooting. Situations sometimes allow me to use an ND or Circular Polarizer filter. Once finished shooting I typically reinstall the clear filter for transport. Protection wise I can't remember ever breaking a filter on the camera. I have dropped a few over the year on had surfaces with shattering results. As far as shooting with a clear or UV filter in front of the lens I have really never understood the logic of covering the front element of an expensive lens with a clear piece of glass that is probably not to the same optical standard as the front element of my lens.
Anyway, keep shooting and enjoy your time behind the lens.
Dale
