tjphoto Posted June 13, 2007 Share #1 Posted June 13, 2007 Advertisement (gone after registration) My nearly new 12mm CV lens hood has stripped threads. Anyone have a handy solution? I took to camera repair place and they want 80.00 USD for re threading. They suggested buying new hood. Sounds like a hassle trying to find one.

hdrmd Posted June 13, 2007 Share #2 Posted June 13, 2007 I have had the same prblem since I bought the lens. A small drop of super glue works fairly well, since there is little reason to remove the hood. DR Link to post Share on other sites More sharing options...
tjphoto Posted June 13, 2007 Author Share #3 Posted June 13, 2007 OK, i remember someone else had this problem also. So, a drop of super glue in the treads will make it stick on? My threads are almost bare. Thanks, Tim Tim Jones Photography Link to post Share on other sites More sharing options...
jlm Posted June 13, 2007 Share #4 Posted June 13, 2007 I have just completed a trial production run of adapters for the 12mm lens that will accept a 55mm IR/UV filter and act as a hood. finish is black anodize, interior is black matte. jm@milich.com pictures to come Link to post Share on other sites More sharing options...

jlm Posted June 13, 2007 Share #6 Posted June 13, 2007 what Guy got: you see one on the lens and one sitting next to it with the retaining ring. Link to post Share on other sites More sharing options...
stephengilbert Posted June 13, 2007 Share #7 Posted June 13, 2007 Advertisement (gone after registration) If the threads are actually stripped (the lock widget turns but doesn't tighten), I'd tap the threads to the next size and buy an appropriate thumbscrew before I'd use glue. Right now you have a good lens and a bad hood. Use glue and you'll still have a bad hood, but will have a bad lens as well. Link to post Share on other sites More sharing options...
tjphoto Posted June 13, 2007 Author Share #8 Posted June 13, 2007 Right. The treads are gone. I like this style of hood and want to keep it. I like the compact nature of it. The repair shop wants 80.00 USD to tap and retread. This seems like way too much. Do all of you have your taps? Were do you get them and how much do they cost?

stephengilbert Posted June 14, 2007 Share #9 Posted June 14, 2007 I haven't bought taps in a long time, and never such small ones. Here's a big set on ebay that'll keep you up to your ears in taps. (eBay: TAP AND DIE - 40 PIECE SET - MM METRIC TOOL KIT (item 200118975985 end time Jun-14-07 20:56:53 PDT)) I'd go to a local hardware store and see if a small set can be had.

mwalker649 Posted June 14, 2007 Share #10 Posted June 14, 2007 It looks like JLM is a good fix to this, mine too stripped. I used a very small black anodized sheet metal srcew to tighten it down. Its not pretty but works. Link to post Share on other sites More sharing options...
Shootist Posted June 14, 2007 Share #11 Posted June 14, 2007 Since the hood is aluminum, I think, the threads will never last when you tighten the screw down and loosen it time and time again. If you plan on tapping it out to a larger thread you might as well do it even bigger and put a stainless steel helicoil (SP) in it. A helicoil is a wound piece of SS that threads into a object and has smaller threads on the inside. They are used on everything that is of good quality and is aluminum that needs to have a screw/bolt in it that is loosened and tightened often.

jlm Posted June 14, 2007 Share #12 Posted June 14, 2007 if you send me your stripped ones, i can helicoil them for a minimal charge. the problem seems to be that Voightlander puts an e-ring on the screw so it will not loosen all the way and fall out. if you unscrew it too far, the e-ring will jam and continued turning will strip the threads. jm@milich.com Link to post Share on other sites More sharing options...
odyocu Posted June 14, 2007 Share #13 Posted June 14, 2007 Why doesn't anyone let CV know about this problem and ask for replacement? I have the same problem and asking now from Stephen to change it. Lens is fine but such a problem appearing in the first use is shame for CV. Seyhun My nearly new 12mm CV lens hood has stripped threads. Anyone have a handy solution?

Guest guy_mancuso Posted June 14, 2007 Share #14 Posted June 14, 2007 John your hood setup is a better design overall anyway and creates more of a shade . Now need to figure a way to get the super glued one off. I really put it on. oh well off to shoot Link to post Share on other sites More sharing options...
