Without thinking I attached a 52mm close-up filter onto the 52mm UV filter that was already on the lens. Now I can't get the Close-up and UV filters apart. They're stuck and won't twist off.

Has anyone any ideas on easy way to get them to seperate? I thought about heating them up to see if they'd loosen, but i'm hesitant to try anything other then twisting them for now.

I know those filters are thin but have you tried the rubber pads used to unscrew jar lids? Might give you a bit more "bite". Maybe lay both filters on a rubber mat of some kind and using down pressure and turning at the same time? A bit of heat applied from a hair dryer (not a heat gun) at the same time might help.

Would cold help more :?:

Metal shrinks when cold... Hot will expand making the fit tighter???
Who am I kidding... they both shrink/expand at the same rate - How about some 2WD :lol: :-) :G

Trout guy has it. Put the rubber pad on a table, place the lense/filter on the pad, push down and turn. The rubber should hold the filter tight enough for you to turn the lense.
Good luck.

It's so uncanny, after I posted my first reply in this thread I had occasion to dig through a bag of old filters and....lo and behold I had a UV and a Cokin holder that were screwed together and probably had been for close to 20 years. I tried my own idea (minus the hair dryer) and it worked fine

About 5 minutes after I made the post I tried again, and this time I got them apart!

I put the two filters back on the lens, and screwed the bottom UV filter in nice and tight. Then I tried to unscrew the Close-up filter and it just twisted off nice and easily!

Best I can figure it is that when I was trying to seperate them when they were off the lens I was pressing too hard trying to get a grip on them and was only forcing them tighter together.

Thankfully the UV filter did not get stuck to the lens either!
