Keeping Lens Filter From Binding Onto Camera Lenses

I frequently use lens filters with my lenses for my landscape photography such as circular polarizers, neutral density filters and step up rings. Inevitably they always seem to get stuck on my lenses at the most inopportune time. I then spend the rest of my photo shoot trying to get the lens off or, if I just leave it on and try to work around it, frustrated that the lens filter is stuck.

Luckily, I have always eventually been able to remove the stuck filter. The same cannot be said for some other photographers I have spoken to. Some of them have had filters on their lenses that have been stuck for years. After the most recent occurrence I started thinking there had to be some way to keep this from continuing to happen. After spending some time researching I finally found a solution that works and thought I would pass it on to my fellow photographers.

From my research there were two (2) primary approaches to keeping lens filters from remaining stuck in perpetuity. The first was using tools to remove filters after they were stuck, the second was taking preemptive action to keep them from getting stuck in the first place.

For removing already stuck lens filters it seems the best tool for the job is a lens filter wrench. These cheap accessories apply equal pressure to the filter and from all accounts easily remove the filter from the lens. The lens wrenches usually come in packs of two (2) and can be had for less than $10.00 at your local photo supply store. Even if you take preemptive actions it is not a bad idea to own and carry this item with you on your photo excursions.

To keep lens filters from becoming stuck in the first place, the best solution is to use good old pencil lead. Turns out pencil lead is primarily made from graphite. Graphite is a great dry lubricant and does not cause a mess, smear on the lens or attract additional dirt and grim that is likely to cause the lens to get stuck even more frequently. Without getting into to much detail, pencils are labeled based upon the level of graphite they contain. The softer the lead the more graphite it contains. The softest pencil available is a 9B the hardest is a 9H. These pencils are typically only found at your local hobby store. However, many people use the standard No. 2 pencil as well. Here is a link to a more detailed explanation of pencil hardness http://www.cultpens.com/pencyclopedia/lead-hardness.

For me I went to my local hobby store and picked up a 6B which happened to be the softest they had in stock at the time. When I got home I proceeded to rub the lead on the threads of my lenses and my filters. I then blew off any excess powder than did not stick to the threads. I am happy to say that I have not had any stuck filters since taking this preemptive action. I also now carry a lead pencil in my photo bag with me and occasionally add a new layer of lubrication to the filters.
