M8 shutter reload problem

Hi there.

 

I am guessing this is the dreaded shutter reloading problem.

 

 

It only seems to happen to my M8 when it gets a bit cold but it's been getting worse over the past few weeks. Today the temperature was about 6 degrees C so not that cold.

 

I bought my camera new about 12 months ago so i hopefully will be able to get it fixed FOC.

 

Please let me know your thoughts and advice.

The shutter cocking action has two things to do; first, it cocks the shutter itself which requires it to move a lever sideways with surprisingly large force acting against the release springs in the shutter. Second, and this is where your camera is failing, it has to prime the release mechanism. This involves move the release lever until it is held in place by a permanent magnet. To release the shutter, a current is passed through the coil in the pictures which counteracts the permanent magnet and lets the release lever go which then releases the shutter.

 

There's a sensor to tell the camera if the release lever has been successfully primed at the end of the cocking cycle. If not, the camera retries repeatedly for a few seconds until it gives up and displays an error message. The magnetic latching depends on the retaining force of the magnet being greater than the force of the springs acting against it and if there is debris on the magnetic pole pieces, that will prevent the magnet from holding.

It's back to Leica pronto so that they fix it under warranty...

I have sent it twice for this.

Tap it from under at the right end to stop the recocking (at least it worked for me).

 

They will probably offer to "clean the magnets", it didnt work for me, so I suggest to insist on exchanging the whole cocking mechanism.

Well my camera went back to Solms about a month ago for the shutter repair and they were gonna repair the coffee ring on the LCD screen too but I have heard through my dealer that they cannot repair the LCD until they have the screen in stock.....at the end of June!!! OH NO!!!!

 

The past month has been like loosing a left hand as I am left handed! and carry my camera with me everywhere, what will I do for another 3 months.

I finally received my M8 back from Solms today.

 

They repaired the shutter and winding mechanism, changed the LDC display (coffee ring) and adjusted and serviced the entire camera. All done under guarantee.

 

I also had a lone camera from them over the past month as I use my M8 as my main source of income.

 

Really helpful staff at the London office and overall a fast repair.

Megadust -- good to hear it worked out in favour for you.

 

I'm experiencing the same problem in low temperatures (below zero °C) -- it might also have to do with relative humidity, not sure. Anyway, happen this winter, and I worked around by removing the battery. Afterwards, the M8 would continue to work properly again for a while, until at some point the problem reappeared.

 

Not the most elegant solution, but as long as I don't NEED to send it in, I won't.

Just an update, got back my camera from Leica, they repaired the shutter and winder for free! Even though it was out of warranty. Thumbs up!

 

Lucky you; I had to pay for mine. When I got it it originally it would do that re-cocking when not really cold (-15 or so, IIRC) so in the winter I just tended to use film cameras. Then, it started doing it above the freezing point; it was time to send it in.

 

I'll have to admit that since I got it repaired, we had a winter, but in retrospect I did not even take the M8 out of its case; I feel quite silly that my main camera is an Olympus 35-rc that was given to me! (the Olympus "just works" so long as there is film in it)

 

I think it's time to get the M8 out; thanks for the unintended kick start.

Had the same problem. After the camera was not in use for a year the second curtain stopped opening after a handful shots. Same as documented in the video above.

Our local Leica Store sent the camera to Solms last week. The camera is already out of warrenty. Currently I wait for the quotation.
