Has anyone ever tried this

I have a 72mm polarizer, I have two lenses who's filter size is 55mm. I was thinking because I don't have the money to buy a stepup ring right now, I might be able to tape the polarizer to the lens. Any suggestions?

Should work. Threads are just a convenience, anyway.

Might be kind of inconvenient to tape it in a way that will still let it turn....

And all that sticky adhesive residue.

Cheers. Mike.

I can tape the bottom half using some not so sticky tape. Besides I'm pretty good at getting sticky tape off.

Thanks for the input. I'm just going to try it anyway. If it works, fine, if not, then I know better next time. And I'll let you know if it worked or not.

It will probably work out just fine.

Cheers. Mike.

72mm CPL can be a very expensive little piece of gear to scratch up the coating for want of a ring. If its a cheap CPL, then consider a cheap 55 CPL (Uncoated Hoya $18+) as it will probably cost less than having to buy the 2 rings ($20) required to do a 55 to 72 stepup.

Just a thought but I know its not as quick or cheap as tape!

What about seeing if museum putty would work?

i don't think this was cheap. It's a Tiffen Circular Polarizer. I bought it a few years ago only to find out I bought the wrong size. But it cost more to send it back than to keep it.

And right now, $18 isn't cheap to me.

What's museum putty, Gary?

If you are going to tape I would probably pick up a role of painters tape...but yes....kinda worries about scratching the coatings. With that said...my Singh-Rays are designed to be held against the lens (or taped)..there is no other way to use them and they don't seem to scratch...and they are $$$$$. Should be OK if you are careful....

It's a bit like play dough, you put it under ornaments and it acts as a non adhesive adhesive. It's popular in California because of earthquakes.
It's also good for attaching posters etc. When you want to remove it, it just peels off without leaving a residue.

Thanks for all the suggestions of what to use. I have some "film" tape here that I use when rolling my own film. It's a bit stiff but I am going to try that first. I'll have to look into getting some "tacky", about the same thing as "Blue Tack" mentioned above. We use it to hold teenagers posters on the wall instead of nails or tacks.

Not sure how much you think a stepup ring would cost, but I did a quick search now and found prices from $2.95 to $14.95, with msot coming in well under $10. Are you *sure* you can't afford one? Seems *way* simpler than messing with tape.

I would hand hold the polarizer before risking the optics coatings with any sort of tape or sticky anything.

I've already handheld a polarizer in front of the lens of a point and shoot with pretty decent results.

If your lenses have hoods, maybe try to make shims to wedge the polarizer inside the hoods.
