Yes
Got my new polariser yesterday and put it on my Sigma 10-20mm. I can't get it off again :(

Am I doing anything wrong? :shrug: Please don't tell me I have to send the lens in to Sigma for repair just for this :'(

Seriously, anyone else had a problem like this before?
 
Try not squeezing the edges of the filter so hard as you try to turn it - that's often what cause sthe problem.

Some further tips HERE

You have to get a good grip of the diameter of the filter that abuts your lens and unscrew it from there as the outer (furthest diameter from the lens) revolves to allow you to alter the effct or the polariser. Hope this makes sense.

Get a can of WD40..............don't laugh!!

Get a sewing needle and form the tiniest of drop on the end, deposit four drops equally around the outside joint between the lens and the filter. Once off clean off the WD40.

Worked a treat for me on a 77mm filter, but remember we are talking tiny amounts of WD40.
 
Following on from CT's advice if Mal's doesn't work....

This might sound stupid at first but read on.....hold the filter and turn the lens (with them off the camera).

The reasoning is....it seems to be an inbuilt thing that we grip the item we're turning tighter than the item we're holding....this is a bad thing with sticking filters so doing the other way around usually helps.

Try putting the palm of your hand flat across the face of the filter and twist. This way, you don't distort the filter mount and the thread doesn't pinch.

Update: Just realised - it's a polariser, so I assume it rotates. Doh. So my suggestion won't work (but it does on ordinary filters).

Bob, that makes a lot of sense to me come to think of it:thumbs:

Put a towel on the table. Lens faces down, push and twist.

These won't work for a polarising filter...due to outer ring

This does for me :lol:
 
Elastic band usually helps with grip. Use one wide enough to cover width of the filter.
 
Try zooming in and out while trying to undo the filter. It worked for a mate of mine. Zoom out a bit, try, a bit further, try again, etc etc.
 
I had a polariser get stuck on my 55mm kit lens.
get a long cable-tie, wrap it around, use the 'tail' as the handle and undo it that way.
popped off nice and easy and if you stick the blade of some tweezers (or similar) into the locking mechanism of the cable tie you can undo it without having to cut anything off(and can re-use it).
I keep a cable-tie in my bag now just in case :)


Admittedly for a 77mm filter you may need two cable-ties...
 
You might want to try using a leather belt wrapped around the filter housing and using the belt as a strap wrench of sorts.
 
Hi

As mentioned above, a wide elastic band might give you more purchase or a cable tie with the teeth on the inside - so they grip the filter - if you have one long enough, you may be able to just hold both ends and use it as a grip rather than fastening it together.

Hope you manage to get it off safetly :thumbs:
 
Henrik, lots of advice and suggestions here, if you have not released it already, lets hope one, or a combination of suggestions work for you:).

it's happened before and I am sure it will happen again

annoys me too, but why worry..........................:shake:
 
Hi, sorry, been away for the weekend. Thanks for all the replies! It's an 82mm polariser so some of them I'll just remember for when I manage to get a non-polariser stuck :thumbs:

I picked up a set of filter wrenches but when I un-packed them realised they were for very small filters. Doesn't seem like you can get them for 82mm...

Anyway, the annoyance of getting the wrong wrenches made me have one last go. Held it as evenly aournd the ring as I could and turned it really hard and it came off.

Thanks
 
I put a very thin smear of vaseline on the filter threads, and don't tighten it all the way up.
 
Just a thought, if a filter is well and firmly stuck, could there be a point at which any further exertion of twisting pressure to remove it may damage the lens.

Ok, will try that. Have certainly learnt not to tighten it a lot now :) I suppose it gets worse with the size of the filter and this it the slim Hoya filter as well at a total of 3mm including the rotating ring.

This is what I was afraid of. I was using quite a lot of force. The lens seems pretty solid though.

the 77mm may work...worth buying as a safeguard...?

............."link".............
 
I use a bottle/jam jar opener to undo stubborn filters, while the lens is off the camera though :)
 
Another thing to try (in future) is to wear a washing-up-glove, you can get a much better grip while using less pressure.



DO NOT WEAR BOTH GLOVES !!!!


or you end up washing the dishes :(

:lol:

good one :D
 
put an elatic band around the filter or a hair band. I've had this problem a few times and it's very easy once the elastic band/hair band is used.

in future just don't screw it on tightly :thumbs:
 
Is it just me , because I do have hand problems , who puts the CPL on , screws it on nicely and then backs it off a teeeny wee bit ?

This ensures it's not absolutely totally hard , immoveably on - it's safe enough , doesn't move till I want it to come off .

Because I do have problems my husband taught me to do this with anything that has to be screwed on - bottles , jars etc etc and for me it does work .
