lpeeples Posted January 24, 2016 Share #21 Posted January 24, 2016 Advertisement (gone after registration) I lost two myself, and ended up buying loctite blue. Dab a bit to the thread before you put it on and no issues since. I will unloosen with a bit of force. Quote Link to post Share on other sites More sharing options...
Advertisement Posted January 24, 2016 Posted January 24, 2016 Hi lpeeples, Take a look here Lost dioptre....again. I'm sure you'll find what you were looking for!
azuled Posted January 27, 2016 Share #22 Posted January 27, 2016 It is very frustrating. I lost two and they are expensive for something that just vanishes. I was in the habit of tightening every time I picked up the camera after the first one went missing, but two days for forgetfulness lost my second one. Fortunately I can see ok, so I just accept scratched glasses now. Quote Link to post Share on other sites More sharing options...
Rick Posted January 27, 2016 Share #23 Posted January 27, 2016 As my ancient eyes aren't what they used to be I use a +1.0 VF dioptre on both my M's. Unfortunately and very irritatingly, I've found that these have a habit of unscrewing themselves and falling off. As a result I have now lost two. At £110 a pop this is an expensive business. It has been suggested by a non photographer that I should use a low strength Loctite on the screw thread but I'm loathed to do so without more informed advice. Any thoughts? Jennifer, Loathed to do so? You don't have to feel hate or feel disgusted to put a small bit of Loctite on the threads. It really isn't that big of a deal. Take a toothpick and dab it into a small dollop of Loctite and then place it on a spot on the threads. I've done it literally thousands of times. Don't you worry yourself about a small spot of Loctite. Hope this helps, Rick Quote Link to post Share on other sites More sharing options...
Exodies Posted January 27, 2016 Share #24 Posted January 27, 2016 I'm sure no one here will loathe you for doing so. Quote Link to post Share on other sites More sharing options...
AndrewDD Posted January 27, 2016 Share #25 Posted January 27, 2016 Mine fell off twice too. I took it along to the Mayfair store, and they glued it on for me. Quote Link to post Share on other sites More sharing options...
Michael Geschlecht Posted January 27, 2016 Share #26 Posted January 27, 2016 Hello Jennifer, A lot of good advice above. Please remember that when you go to put loctite/nail polish on the screw threads you only need a small drop at the top (last engaging) part of the screw thread. If a part of 1 or 2 threads partially have some loctite/nail polish on them that will be more than sufficient. 1 advantage of nail polish is that it is more visible than loctite & it holds/releases just as well. Best Regards, Michael Quote Link to post Share on other sites More sharing options...

Peter Kilmister Posted January 28, 2016 Share #29 Posted January 28, 2016 Spelling ... always a problem. COFD & chips advertised in a pub. I said, "Excuse me, surely there's no F in COD," and the barmaid said, "True ... and there's no F in haddock either." 1 Quote Link to post Share on other sites More sharing options...
Guest Posted July 27, 2018 Share #30 Posted July 27, 2018 Well at least I'm not the only plonker that has lost a diopter..,.seems like it's quit common. I've decided to go the super glue rought.......can't see the point of piddling around with tape or toothpaste Neil Quote Link to post Share on other sites More sharing options...
Jeff S Posted July 27, 2018 Share #31 Posted July 27, 2018 Super glue? Bad idea. Jeff Quote Link to post Share on other sites More sharing options...
sblutter Posted July 29, 2018 Share #32 Posted July 29, 2018 have a look at https://www.engelbert-strauss.co.uk/Tools_Equipment/Site_Accessories/Glues/Screw_locking_device-7210050-5097083-0-0.html just as suggestion. Thomas In the States we have what looks to be the same blue liquid - Lok Tite. Comes in medium strength, should do the job Quote Link to post Share on other sites More sharing options...

I've decided to go the super glue rought.......can't see the point of piddling around with tape or toothpaste Neil Super glue can 'fog' as it dries, especially in humid climates, and while it might be cleaned off the outside of the camera you've got to be aware a white fog especially on the inside of the viewfinder could be irritating to say the least. Blue thread locking compound is the answer, and don't let anybody try to sell you the red variety. Quote Link to post Share on other sites More sharing options...
Ernstk Posted July 31, 2018 Share #34 Posted July 31, 2018 I use a -1.5 dioptre and I move it between my M8 and M-P. I've been doing this for 2 years and never had any issues with it coming loose on either camera. Ernst Quote Link to post Share on other sites More sharing options...
