mutanthands Posted February 5, 2016 Share #1 Posted February 5, 2016 Advertisement (gone after registration) Hello collective team! I was wondering if anyone might be able to help with my current conundrum; As I'm doing a bit of travelling I picked up a 21mm Voigtlander 1.8 Ulton, along with a Hoya PL filter. So far so good, love the lens. However I put in the PL filter and now I can't get the blooming thing off! It wasn't over-tightened so I know it's to do with the filter material, ie. Not brass. The tricky part is that the lens design has a built in hood which can't be removed, but it also means I can't get a proper grip on the filter, not lay it flat on a rubber grip pad. If anyone has an idea on how to remove it, it would be greatly appreciated! Quote Link to post Share on other sites More sharing options...

wattsy Posted February 5, 2016 Share #2 Posted February 5, 2016 Can you get an elastic (rubber) band around the filter rim? If you can that will help maintain sufficient grip to turn the filter. Quote Link to post Share on other sites More sharing options...
stevieg Posted February 5, 2016 Share #3 Posted February 5, 2016 Direct pressure over the end of the filter rim, along with a twisting motion will usually loosen the thread. With no lens hood on, the best way is to have a lens cloth in one's palm and press the end of the lens/filter onto it and "twist off". Looking at images of your lens, I would be looking to find a cylindrical piece of wood/plastic, matching the diameter of the filter to bypass the fixed filter, in order to rotate the end of the filter. There doesn't seem to be room to use the usual filter grippers! Alternatively, a single length of wood/plastic held flat over filter end in between the lens hood petals could twist off the filter when axial force is applied at the same time as twisting. My understanding and experience with filters is that any side gripping force simply locks the thread more firmly and doesn't allow removal, so "end-on" force to hold the filter, along with a twisting force is what is needed. Good luck!! Quote Link to post Share on other sites More sharing options...
gpwhite Posted February 5, 2016 Share #4 Posted February 5, 2016 The Zeiss 15mm f/2.8 is prone to the same issue. The problem is that the thread pitch on the lens is different than the filter, so things get jammed. I solved the problem on the Zeiss with the following approach: Patience, patience and more patience Realize that the filter might be damaged (then discard) in order to save the lens Using a cloth, or better yet a small slab of soft balsa wood, press down onto the top (front) of the filter collar with as much force as you can control without breaking the filter glass down onto the lens front element. Apply a very slow anti-clockwise rotation to get things going... like how a large locomotive starts from rest. You will get it. 1 Quote Link to post Share on other sites More sharing options...
jaapv Posted February 5, 2016 Share #5 Posted February 5, 2016 Find a fitting cork, press the filter down on it and unscrew. Quote Link to post Share on other sites More sharing options...
Schrödinger's cat Posted February 5, 2016 Share #6 Posted February 5, 2016 Find a fitting cork, press the filter down on it and unscrew. I have done this very thing using a hard rubber laboratory stopper. It worked perfectly, but without access to a chemical laboratory the stoppers are sort of thin on the ground Quote Link to post Share on other sites More sharing options...

farnz Posted February 5, 2016 Share #8 Posted February 5, 2016 The simplest remedy in my experience is to find a shoe with a rubber sole, push the filter flat against the sole and twist the lens steadily until the filter comes free. This method evenly distributes the torsional force around the filter's rim rather than other methods which apply the force at specific points (through the fingers) and distorts the filter causing it to bind more tightly. Since many people wear shoes with rubber soles you're likely to have the solution with you or close at hand most of the the time.

farnz Posted February 5, 2016 Share #10 Posted February 5, 2016 Difficult as the hood is a fixture. Oops, missed that sorry. In that case you might be successful using a rubber-clad heel of a woman's shoe that fits inside and far enough into the hood. Best of luck. Pete.

Stealth3kpl Posted February 5, 2016 Share #11 Posted February 5, 2016 I think the problem is it is a polarising filter so pressing it onto a cork or rubber mat just revolves the polariser's outer ring. Pete 2 Quote Link to post Share on other sites More sharing options...
stevesurf Posted February 5, 2016 Share #12 Posted February 5, 2016 Here's an interesting video illustrating the "rubber band technique with a polarizing filter: https://youtu.be/A89HP625WcU?t=1m18s Here's the hair dryer and oil lubricant (be really really careful and invert the lens) methods: https://youtu.be/qsSds4z2Ruw?t=19s Quote Link to post Share on other sites More sharing options...
sblitz Posted February 5, 2016 Share #13 Posted February 5, 2016 Was it cold out? I have had that problem of late and when the camera has warmed up a bit the filter came off easily. If temperature does work use a vise-grip pliers with some cloth so you don't have metal on metal and proceed GENTLY.....I did once, no problem.

NickR Posted February 6, 2016 Share #14 Posted February 6, 2016 Sorry to hear about your stuck filter but now I know to never put a PL on my Voigtlander with a built-in hood. You can try screwing another filter into the stuck filter. This is to keep the stuck ring from distorting from the uneven pressure applied between the hood tulips. With the PL, however, I'm not sure it would help. Quote Link to post Share on other sites More sharing options...
Stealth3kpl Posted February 6, 2016 Share #15 Posted February 6, 2016 (edited) Are you certain the hood doesn't screw off? Many don't realise the 25/4 Color Skopar hood unscrews. Perhaps it's the same with your 21 Ultron. Edit: Oh, having looked at a picture of the Ultron it does look irremovable :-( Pete Edited February 6, 2016 by Stealth3kpl Quote Link to post Share on other sites More sharing options...
mutanthands Posted February 6, 2016 Author Share #16 Posted February 6, 2016 Thanks a lot for the suggestions, being a PL filter certainly adds to the complication! I think the elastic band suggestion might have some legs. Currently traveling in a country when my vocabulary is somewhat limited, but the challenge is half the fun...right? NickR - yes don't do it! Or if you do make sure you have a brass B+W on as a base filter. Glad that some good can come from the whole ordeal though! Quote Link to post Share on other sites More sharing options...
Herr Barnack Posted February 7, 2016 Share #17 Posted February 7, 2016 (edited) I use one of these and have found them to be very effective at removing stuck filters. I always have one in my camera bag, just in case - http://www.amazon.com/Jar-Wrestler-Silicone-Grip/dp/B00WTSLA4G/ref=sr_1_21/189-8134016-5696062?s=home-garden&ie=UTF8&qid=1454865174&sr=1-21&keywords=black+and+decker+jar+openers To use this on a polarizing filter, I would wrap it around the outside of the rings and try to get a grip on the ring closest to the lens. I have not used one of these but this might be effective on a stuck polarizing filter if the above item does not work - http://www.amazon.com/Kitchen-Kahuna-Silicone-Easy-Opener/dp/B00RPNG93M/ref=sr_1_20?s=home-garden&ie=UTF8&qid=1454865585&sr=1-20&keywords=black+and+decker+jar+openers Edited February 7, 2016 by Carlos Danger Quote Link to post Share on other sites More sharing options...
George Stoichev Posted February 5, 2022 Share #18 Posted February 5, 2022 After hours of suffering with the UV filter of my Summicron M 50mm I went to the basement and found these 2 eur rubber gloves. You can’t imagine how easy the filter unscrew with them Welcome, dear visitor!

arttux Posted February 9, 2022 Share #19 Posted February 9, 2022 I got a stuck filter from my V5 Summicron by wedging the tip of a tiny flathead screwdriver between the filter and the lens few times. Didn't have to use any force. I heard a click and the screws of the filter got re-aligned with the lens. 1 Quote Link to post Share on other sites More sharing options...
