texasrancher Posted March 30, 2008 Share #22 Â Posted March 30, 2008 I use a Leica Universal Polarizer coupled with both 39 mm & 46 mm UV/IR filters with great frequency - and the adapter often gets stuck to the filter as you described. It happened to me again last October at the Yosemite Workshop put together by Jack Flesher and Guy Mancuzo, but fortunately Jim Butler (husband of western regional Leica rep Linda Leslie-Butler) had the perfect cure. The solution is much as described by others above in eliminating the uneven torqueing that appears to be the problem causing the "stuck as if welded" problem. Jim suggested using the tips of my first three fingers and the thumb, positioned in a diamond pattern along the outer rim of the filter, to gently rotate the filter out of the bound position - takes very little practice and has worked repeatedly for me. It is frustrating when you are attempting to change lenses in a hurry, but requires no more equipment than you have "at your fingertips" every day. The idea is to evenly disperse to rotating force along the outer surface of the filter mount without having the filter dig into the adapter. Good luck!

lm_user Posted June 4, 2015 Share #23 Â Posted June 4, 2015 Found myself in the same predicament yesterday. Used a rubber band around the circumference of the filter and applied rotational force to filter by pulling on the rubber band in the desired direction Filter loosened right away. Same principle as a previous post described using tape Link to post Share on other sites More sharing options...
gbealnz Posted June 4, 2015 Share #24 Â Posted June 4, 2015 Old thread, but definitley had a chuckle at Pete's "white shirt" advice. I always use a section of old "inner tube rubber". I have a piece about 75mm square, and place that on a hard surface (bench or table etc). Then the filter or lens or whatever directly onto the rubber. Push down from the top and twist. Works every time. Gary Link to post Share on other sites More sharing options...
Loren Posted June 4, 2015 Share #25 Â Posted June 4, 2015 The joys of dissimilar metals! It sounds like you have galvanic action going on here. It gets worse in a corrosive environment. Â As suggested before, try using a pencil to lubricate the threads with graphite before mating. Â Although a little more problematic (messy), a very fine coat of Anti-Sieze from an automotive shop will also work. Â A better alternative might be to try to replace the UV/IR cut filter with a B+W version. Link to post Share on other sites More sharing options...
lm_user Posted June 5, 2015 Share #26 Â Posted June 5, 2015 I have both Leica and BW uv/ir cut filters. Why is the BW filter better? Link to post Share on other sites More sharing options...
Loren Posted June 5, 2015 Share #27 Â Posted June 5, 2015 Advertisement (gone after registration) I have both Leica and BW uv/ir cut filters. Why is the BW filter better? I'm only speculating that the material used for the ring and threads will be different. Link to post Share on other sites More sharing options...
jaapv Posted June 5, 2015 Share #28 Â Posted June 5, 2015 I have both Leica and BW uv/ir cut filters. Why is the BW filter better? B&W is said to use higher rated glass and coatings than Marumi. Leica order their IR filters from Marumi (allegedly). Other Leica filters are by Schott, AKA B&W, but at the time that Leica needed a large number of IR/UV cut filters early 2007 the only company able to supply sufficient quantities was Marumi. According to an inside source at the time Schott was royally not pleased -understandably-. Link to post Share on other sites More sharing options...
tobey bilek Posted June 8, 2015 Share #29 Â Posted June 8, 2015 The lens shade from my 25 mm snapshot skopar became stuck, aluminum shade, aluminum lens. Â Was not over tightened. Â Grabbed at one point with finger and thumb so no distortion of the shade was possible. Â Worked. Â I put a trace amount of silicone grease from the plumbing aisle on the male threads and then wiped off what I could. Â Has not stuck since. Â Â I only wish I could cure the decentering that shows on digital that easily. Â That was the last CV lens I bought and most likely will ever buy. Â The Leica products put them to shame.

enboe Posted June 13, 2015 Share #30 Â Posted June 13, 2015 Being a male approaching 50 this year, I went in for "that" exam recently. Â When the doctor put on those purple nitrile gloves, it reminded me they have a less nefarious purpose. Â I use (not reuse) the powder-free nitrile gloves to unstick anything stuck on cameras, filters, M6/M7/MP battery compartment lids, etc. Link to post Share on other sites More sharing options...
