I was traveling and i noticed my dot has broke off. I didnt mind it so much until a few weeks later i noticed there was a hole in it. I went to Leica SF and asked them if they had spare parts for it, which they did not but was helpful enough to order some from Germany. Do you guys have any suggestions on what kind of glue or epoxy i should use? The employee at Leica was clueless on what to use. Any help will be appreciated. Btw the dots were free

When the red dot fell off my old and beloved v4 35/2, Jimmy at Leica Mayfair (London) superglued a new on one without issue. I asked if it was a special glue from the motherland and he said 'sure...'. It wasn't. It was just normal widely available superglue. Good luck. That dot will help with photos but on a serious note, at least it won't allow light into the film chamber.

Yeah I was worried about light leaks thats the only reason i wanted to get this fixed. I was thinking super glue but when it dries it can get flaky and i would'nt want that near my film.

I think you'll only need a small drop of glue. Mask off the other side to be safe. Or have a tech do it.

From my experience super glue is not too effective with shear loads. I'd look for something more elastic; should be plenty on the DIY shelves.

I have a film in mine at the moment so can't look but I think the peg may have originally been heated/melted to fix the bump stop in place. You could try the tip of a soldering iron or heat a nail head over a flame and press against the peg to flatten it. If not superglue, but use one of the flexible type, not the hard rigid version.

Consider a small (and I mean small, just the faintest amount) of black silicon sealant. It will last nearly as long as the camera.

 

PS I'm so envious of your MP !!

Phew! You almost got charged 950$ but you never knew about it. You're lucky to have ended up receiving them for free.

Hallo,

Look here: Leica M

[colint544]

My M5 has no dots on the back door, just two flat circular spaces where the dots should be. There are no problems with light leaks. But what on Earth are the dots for??

Tooling aids during manufacture, maybe.

The plastic dots are bump stops to keep the back door from getting scratched when it is fully open, which is why when gone they're not often replaced because they aren't a mechanical necessity. You can make your own if you have a suitable size punch and a model shop nearby who can sell you some 20 thou black polystyrene sheet.

Thank you for that!
