The B&W thread ring is made out of brass. Under most conditions brass is softer than aluminum. It's not hard to accept the possibility that the B&W filter threads would absorb more damage than the aluminum threads on the lens. The softer brass threads on the B&W filters also make it easier to remove the filter if it had been over-tightened when it was installed.

Yes, but if the filter is installed on the lens the filter, lets say brass, threads are going to be screwed into the len's threads. I just have a hard time visualizing how the filter threads could be damaged and the len's threads not damaged. The only scenario I can imagine is that the filter would have to be crushed toward the lens and the brass thread ring of the filter perhaps pulled in toward the center of the filter. That is why I would love to see a photo or two of the results.

Best,
Todd Ferguson

I do not any longer use UV filters. But when I did I had a 52mm Nikon UV attached to a Nikon 105 2.5 manual focus lens. I dropped it and the corner of the filter bent (a lot) and the corner of the glass on the filter was smashed, but the threads on the filter and the threads on the lens were not damaged at all.

Have had a couple of similar experiences.

What is the best way to protect lens? Like UV filter? I have Tameron 150-600mm lens. Polarizing filter I have bought degrades the picture, when I enlarge/crop he jpeg pictures. Should I invest in UV filter for protection of lens?

You decide.

Dang. A visual to show how a UV filter can protect the front glass of a camera lens. Case closed.

The pictures resemble my experience with smashed UV filters.

I saw 5 pages of pontificating by those with absolutely no experience how filters do not protect. Google is so easy to show all that BS is just that.

Your comment appears to box others supporting UV filters into proving a negative, which is impossible.

On the other side, your view would have to show by example that a UV filter cannot protect a lens optic. This view of non-protection now flies in the face of visual evidence showing the obvious opposite: UV filter protection of a camera lens from damage.

Your role as a contrarian may continue yet for now it survives by insistence not by physical proof.

Yeah photos of real instances are not proof or of value.
Truth hurts.

Thanks. The discussion clarifies species of erroneous thinking processes.

To use a protective filter or not to. Right up there with Canon or Nikon, Chevy or ford. I only use one in harsh environments. But if it hepls you sleep at night go ahead. Just be sure to use a good one.

Agree. I posted before on this subject before. Dropped my macro lens. The UV filter was shattered and the screw threads it attaches with were damaged but the important part, the lens itself, is fine. You'll hear that it puts one more factor between the lens and the sensor. True. But if you buy the best and keep it clean, spotless, you'll do fine. And it will protect your lens to a certain extent.

That is up to you. A polarizing filter does not degrade the photo.

But it can cause the loss of up to one stop of light entering the camera. It does affect the image.

Some Polarizing Filters can cost 2 stops of light. I think the main issue here was UV filter for protection...

When you dropped your camera did you have a Lens hood on your Lens?
