Seized Filter on 24-70 L

[boku]

I hope someone can tell me a safe way of removing a seized filter on this lens. I need help ASAP. I am desparate.

Try a rubber band wrapped around the filter.  Should give you some extra grip.

(Obviously do not force it and do not go nuts with wd40.  But then you knew all that.)

I'm not sure what the US/Canadian equivilent of jessops is, but they sell filter wrenches.

Failing that, you either need to heat the filter or cool the lens, and I wouldn't allow a blow torch anywhere near one of mine....

Remember though, the filter needs to stay warmer than the barrel so sticking it in the freezer overnight won't help.

Worked like a charm. Henceforth, I hold you in the highest regard, sir! Thank You.

Bob, does this mean that previously you held DarkPenguin in low esteem?

(Nearly) on this subject, is there any lubricant one can use to keep one's polarizer turning smoothly? As much as those B+H jobs cost (I had to buy a 95mm one!! Yikes!) they should twist themselves.

I wouldn't have the guts to experiment with that.

Rubber bands come in handy when you are out in the sun and your aluminum filter bakes before the lens does.

I had a polarizer stick to where even a rubber band didn't help.  The trick that worked was to wrap 4 or 5 layers of masking tape around the edge and that gave enough material to grab onto to get it un-stuck (so now I always carry a roll).

High esteem, now high regard as well!

One of the main reasons that I purposely buy B+W filters is because they have brass mounts that are not likely to seize. I still think that is valid.

I mounted this filter a few days ago outdoors - it was 20 degrees F at the time. All the brass in the world can't overcome differential expansion of dissimilar metals.

Learned a lesson today!
