Re: How to Remove Stuck Adapter Ring on Filter that Already Stuck on Lens?

Try cold! First cold air from outlet of your car's air conditioner. The idea is, cold causes metal to contract. You want to cool the filter ring and not the lens. Not an easy task. If cold air from the air conditioner won't work, put ice in a plastic bag and hold the filter to the bag. Last resort, go to an electronic store and buy a can of freezing spray. This is used in electronics to super cool parts on a circuit board. About $20. This aerosol can has a fine diameter tube that plugs into the spray nozzle. This adds spot control. Spray the filter ring. Naturally there is danger in using such a super cooler method. You may crack the filter or worse.
