Filter fell apart

Has this happened to anyone? While removing my Hoya uv filter from the lens, I happened to drop it to the floor. Nothing fractured but the glass part separated from the metal ring. The ring does not seem distorted or bent. So what is best way to reattach glass to ring? And which side does it go on? The part facing into the lens or away from the lens? It seems to fit easiest on the inner position. I was thinking of a few drops of superglue on the ring rim. Thanks for advice!

Probably the best thing to do is toss it.

Some filters use a "snap ring" to hold the element in place. If that's the case for you, drop the glass back into the holder (direction shouldn't matter) and find that snap ring. It looks like a incomplete circle- a metallic ring with a short piece missing. Otherwise, you can stuff some black paper into the snap ring's receiver/groove- tamp it in with a toothpick- don't scratch the glass- and plan on regularly tending to the stuffing... or just chuck the thing. If you've the filter type that screw apart- the glass sandwiched between two threaded halves... find the other half... or chuck the thing. If your filter is just pressed together to clamp the glass in place... chuck the thing-

I'd super-glue it if it won't snap into place. If you do it carefully and allign it properly, it shouldn't affect the optics, and work just as before. Toss it only if money means nothing to you.

If he is not extremely careful with the super glue or uses the wrong viscosity, he may get glue on the filter glass or even the filter thread. Depending on the size and model number and quality of his Hoya filter, which the OP hasn't shared, replacing it with a new filter could be as little as $15. In any case, I would never trust using a filter on my gear that I had to glue back together.

I don't see any type of snap ring attachment. Will try to glue it and see how it does. Thanks for tips!

just be very careful and test pre fit the glass to make sure it can be set in to the right position . Once the superglue is applied it sets up so quickly there is no second chance. Its not something I would waste my time with, but its your decision so I hope you can get the result you want.

This happened to me also with a Hoya filter only I didn't drop mine. I was walking with the camera strap over my shoulder and I noticed a dark round piece of glass on the ground. It was the front half of my polarizer. Have no idea how it happened but I don't buy their filters anymore.

So I put some superglue drops on the rim with a toothpick and placed the glass on it. So far seems to be holding firmly, didn't make a big mess. See what happens.

Don't use super glue ...it can damage the filters coating . A small amount of contact cement would be best . Apply a tiny amount to the inside of the ring then insert the glass .Good Luck....

check your floor for the snap ring. hoya filters usually have the glass held in by these. sometimes it is a small threaded ring.

You need to read the whole thread. In the post just above yours the OP indicated he already superglued it.

Super glue is the way...just don't drop it again, there is no Super glue 2.
