the subject says information technology all...
I seem to accept managed to cross a skylight filter on my LUMIX DCM GF1 14 - 42mm lens...
Is there anything I can do?
A set of filter wrenches from your local photographic camera shop should help.
I forgot to mention I'chiliad in Guatemala.
A scrap of safety (jar opener, wheel tire, glove) are recommended here:

Assuming its jammed on - if you dont have access to filter wrenches, y'all might notice your local boat mechanic has an oil filter wrench thats small enough to fit, or can be packed to fit. Its important to utilise force per unit area evenly all round the filter to enable information technology to come off. Simply holding and squeezing it jams it tightly in place.
In one case its off it'southward possible to re-thread if its non too badly damaged using a NEW sacrificial filter which can be screwed into the damaged threads advisedly, using a small amount of suitable lubricant - NOT OIL - but something like soft pencil lead graphite which can be 'scribbled' into the threads to ease the new filter into identify. Pay attending to the angle the new filter goes in at to try to ensure its parallel.
Once yous get information technology off the lens a simple solution would exist to become a step-up ring which suits your photographic camera and glue the damaged filter to it ... like if the camera has a 55mm thread they you would go a 55<57mm stride-up. The rings are much cheaper than filters
Is it __really__ cross-threaded or just stuck?
Cross-threading is possible but difficult, equally it requires force to mate the ii items in the get-go place.
Much more likely the filter is just seized to the lens.
Gentle pressure evenly applied to the ring is the all-time solution in either instance.

Yay, I managed to become information technology off - mostly past elementary persistence. I tried using rubber from a bicycle inner tube to grip it and information technology didn't really seem to work but it might have loosened information technology enough that when I when back to brute force it gave.
The lens filter is a cheap one bought off the streets of Mexico City and might be a bit dodgy.
Anyway, all practiced now. Thanks.
I one time crossthreaded a filter while in a bustle and for the life of me was not able to get it off only by hand. When I got home I used a rubber mat for removing stuck jar lids and it worked like a gnaw. Yous may exist able to get the filter off, but depending on the amount of crossthreadiing, the filter may exist worthless for futurity employ. The easiest way I have plant to prevent crossthreading is to place the filter on the forepart of the lens and rotate information technology backwards until y'all hear or feel a "click". That tells y'all it is properly seated. And then just carefully rotate it on the proper management and you should be fine.
I proceed 1 of those adustable rubber belt and handle style jar openers in my camera bag for just such an occasion. Also works wonders when I overtighten my monopod to the lens collar. They come up in a variety of sizes (Tool dept.) or you can get them in the kitchen gadgets aisle at any number of stores. They're inexpensive and very constructive.
I had a cross threaded B+W filter on my Canon 28-70mm lens, which I was actually quite reluctant to break. So after trying industrial levels of sheer beast strength, a rubber grib and selective refrigeration and failing - I used an approach that I didn't see when trawling the internet for a possible solution. In my case, the lens was cross threaded leaving a small gap between the filter and the lens. I decided to attempt the following approach - I ran a hard tipped felt tip pen ('Berol Handwriting') round and round between the filter and lens with a reasonable amount of pressure until I managed to pop the filter back across the lens threads and back into line. I was then able to twist it off as usual. Promise this helps someone else.
