Advertisement Posted September 1, 2007 Posted September 1, 2007 Hi j. borger, Take a look here UV/IR Filters not as rugged..... I'm sure you'll find what you were looking for!
jrc Posted September 2, 2007 Share #22 Posted September 2, 2007 Yeah, I was kind of surprised at the Leica filters...I haven't gotten one stuck yet, but I bought a set of plastic Adorama filter wrenches when I had a stuck filter on a Nikon lens; they're cheap, light and take up no room, so they might not be a bad idea if Adorama still sells them....Anybody know what the wait on coding is in NJ now? I still have two lenses to go... JC Link to post Share on other sites More sharing options...
farnz Posted September 2, 2007 Share #23 Posted September 2, 2007 I've always found that a thick rubber band does a very good job of unsticking filters. There's always one resident in my gadget bag. If the rubber band still doesn't budge them then try gently warming the threads (even armpit warmth will sometimes do the trick) so that they expand then they should part fairly easily. (Just try not to get sectioned for walking around with a lens in your armpit! ) Pete. Link to post Share on other sites More sharing options...
dspeltz Posted September 2, 2007 Share #24 Posted September 2, 2007 The Leica filters stick. Perhaps because they are aluminum. But they really can stick. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted September 2, 2007 Share #25 Posted September 2, 2007 Going back to the grease maybe that lithium stuff would be better. Extremely small amount Link to post Share on other sites More sharing options...

(Just try not to get sectioned for walking around with a lens in your armpit! ) Pete. the best technique I have found for removing a stuck filter is to use a soft rubber soled shoe or some such other flat & firm bit of soft rubber place the stuck filter flat against the rubber and turn using firm pressure on the rubber surface against the filter this works well as it evenly distributes the turning energy over the entire ring ...turning the ring at the side causes uneven distribution of torque which can cause the ring to bind up further this technique has gotten some pretty stubborn rings off for me when other measures such as rubber bands or heating failed ...I never tried the armpit treatment however Link to post Share on other sites More sharing options...
ho_co Posted September 2, 2007 Share #27 Posted September 2, 2007 Advertisement (gone after registration) Yes, I agree the Leica filters are not as well made as the B+W filters. The B+W retaining ring is superior to the spring ring used in the Leica filters, which is tricky to remove if you're trying to extract the glass (for the Milich filter holder).... Mark-- Not to disagree with your assessment of the mechanical differences between the two methods of retaining the filter glass, but Leica has always maintained that the retaining spring is better optically because it doesn't hold the glass so tightly and can adjust to thermal expansion. Because it hasn't as much 'give,' a screw-in retaining ring can cause strains in the glass and reduce image quality. Amazing the things one learns to explain when one works for the company! --HC Link to post Share on other sites More sharing options...
