jhawker Posted May 3, 2007 Share #1 Posted May 3, 2007 Advertisement (gone after registration) Hello all. I am writung to inquire if any of you have experienced the shutter recocking multiple times after an exposure? This may go on for as little as 1 second to as much as 5-10 seconds. It will continue after turning the power off also. While it is occuring no additional exposures can be made. My camera is number 3105xxx. I have upgraded to 1.102 and installed it a second time. Although it did this with both previous firmware versions and continues today. While the camera does not fail to record the exposure that starts the multiple cocking to the card it is becoming a nuisance. Is there something I may be doing to cause this? Thanks in advance for your attention. JH Link to post Share on other sites More sharing options...

marknorton Posted August 24, 2007 Share #6 Posted August 24, 2007 The shutter has a locking mechanism which is designed to prevent accidental actuation of the shutter. The shutter is released/controlled by a pair of small solenoids - an electromagnet with a moving armature or plate - pass a current through it the electromagnet and the armature moves to activate the shutter. For accurate shutter timing, these components are small and lightweight so that they can be made to move quickly. Without the shutter lock, it would be possible to trigger the shutter by jarring the camera; when I took my camera apart, I was extremely careful to avoid subjecting the shutter to shocks because I did not know what the consequences of accidental activation were. There are powerful springs in there and I could imagine mangled shutter blades ruining my day. So, when the shutter is cocked, the electronics and software is looking both for the correct motion of the shutter cocking lever and the correct locking action of the shutter lock. These are indicated by two optical sensors (LED/Photo Diode) where a blade interrupts the light to indicate a particular state. If the shutter is repeatedly trying to cock itself, it's likely that the motion of the shutter cocking motor is correct but that the shutter lock is not being set correctly at the end of the stroke. The software will be programmed to recognise this as a rare but expected condition and the recovery is to retry the shutter cocking. Most often, a second attempt will sort it out; otherwise multiple attempts will be made with presumably some upper limit on the retry attempts. If it hasn't worked after 5 or 10 seconds, it's not going to. The problem could be mechanical - a mis-alignment of the lever which causes the shutter to be locked - or electrical. The shutter lock is a permanent magnet solenoid and current through it will release the lock. Current leaking through it might prevent it locking at all; equally, the sensor which detects the shutter is locked may be faulty.

marknorton Posted August 24, 2007 Share #7 Posted August 24, 2007 Advertisement (gone after registration) If you have this problem, try this... While the shutter is repeatedly trying to cock itself, hold the camera in one hand and tap it repeatedly onto the open palm of your other hand - not hard, obviously, but enough to try to get the shutter lock to engage.

okram Posted August 24, 2007 Share #8 Posted August 24, 2007 I`ve had this, but only vith Transcend 4Gb card. The moment i have changed the card, the problem stopped. I wrote a letter to solms snd they sad that this is possible cause. This happened two months ago, and 3000shots later never again (with Sandisk ex3 2gb) Marko Link to post Share on other sites More sharing options...
marknorton Posted August 24, 2007 Share #9 Posted August 24, 2007 Tough to see how the choice of memory card could affect the shutter cocking action unless it was some sort of power interaction. Sounds like clutching at straws to me... Link to post Share on other sites More sharing options...
JT07 Posted August 24, 2007 Share #10 Posted August 24, 2007 Thanks for the detail and pics Mark. Good stuff, explained well. I've have the same memory card since day one with the camera back in Feb so I can't see it being the card. I was hoping a firmware issue but it happened before I upgraded to the newest firmware and also after updating. I'm going to bring it by the shop I bought it at to see what they think.

jhawker Posted August 24, 2007 Author Share #11 Posted August 24, 2007 Good morning. I thought this thread had disappeared. To answer your question, Yes, I've had the cameara repaired. Leica did the repair under warranty in New Jersey it took about three weeks total. I have 1500 plus photographs since the repair without a problem. Thanks to all the other responders explaining this problem in detail. JH Link to post Share on other sites More sharing options...
marknorton Posted August 24, 2007 Share #12 Posted August 24, 2007 As a post-script, it was the release of the shutter lock which caused the change in shutter noise in 1.102. The shutter lock is released early in the cycle, presumably to make sure it does not in any way impede the movement of the shutter cocking lever during the shutter release. Leica talked about increased shutter precision. They may have found some inconsistency of the shutter opening and uneven exposure across the frame.

rdubois Posted May 21, 2008 Share #13 Posted May 21, 2008 I realise this is a very old thread but I have just received my M8 back from Solms after a tune up of the rangefinder and a few other matters and have some information which may be helpful. Mark Norton's opinion would be particularly helpful. The camera was returned beautifully packaged but with battery removed. As soon as I inserted the battery there was a lot of whirring and then "Achtung Shutter Failure" I tried with a new battery but with the same problem repeating time and time again. After an hour or so I tried again and the camera was behaving quite normally. Could it be that the internal battery was too low or some other charge related problem? I am awaiting for an answer from Solms and will post if of further interest. As an (important) aside many compliments to the Leica service team which dealt with my request for the warranty service to treat front focusing with an amazing efficiency and speed. They were gracious enough to tune the camera to the two Zeiss lenses even though they had absolutely no obligation to do so and even returned them in neat little pouches. Glad to have the M8 back as I had forgotten how heavy a Canon and 135mm lens system is Dubois Link to post Share on other sites More sharing options...
dlc43 Posted May 21, 2008 Share #14 Posted May 21, 2008 I had the exact same problem. I sent it to NJ. In the end they replaced my camera with a new one. Link to post Share on other sites More sharing options...
TDR Posted May 22, 2008 Share #15 Posted May 22, 2008 I know that there has been a lot written about the surprisingly loud noise of the shutter and shutter cocking. But why is it that my M8 has a shutter cocking noise that my Nikons don't? The Nikons are just "click." The Leica's "click" is quiet but it is followed by the whiny shutter-cocking sound. Why does the Leica have that sound when the Nikons don't? -Tim Link to post Share on other sites More sharing options...
scott kirkpatrick Posted May 25, 2008 Share #16 Posted May 25, 2008 I just had a "drive blocked/shutter fault" error condition in my Dec 2006 M8, with current firmware as of May 2008. 9400 actuations previously with no problems. I couldn't find more than two or three similar errors reported in the forum using the search line. Have there been others? The battery was at one bar when it happened, but replacing it with a fully charged battery and taking the battery out for three hours then replacing it hasn't made a difference. Still stuck, and will probably send it in next week. scott Link to post Share on other sites More sharing options...
gwelland Posted October 1, 2008 Share #17 Posted October 1, 2008 I seem to have joined the random shutter recock problem club. Last week I had a weird situation where the shutter recock fired continuously for about 5-10 seconds or so and then stopped. Afterwards everything went back to normal for a while. Later the camera started randomly firing off a second recock after shooting - not every time but once in a while. Then, everything went back to normal. Tonight I was out shooting and the random double/triple recock returned. Question is, what to do with the camera. It's under warranty still so I know I can send it to NJ. The dilemma is that I've also called to get in the shutter upgrade queue. I'd like to get it fixed asap but i'd also rather not have it fixed and then send it again afterwards for the upgrade. The other dilemma is that I suspect that sending in a camera with a faulty shutter might cause a problem at upgrade time. Thoughts? Link to post Share on other sites More sharing options...
marknorton Posted October 1, 2008 Share #18 Posted October 1, 2008 No point in doing things twice, so I'd just wait for the upgrade timeslot. Can't see how it would cause a problem, especially if the camera is in warranty. Link to post Share on other sites More sharing options...

The other dilemma is that I suspect that sending in a camera with a faulty shutter might cause a problem at upgrade time. Thoughts? Unfortunately, I have to join the club of random multiple recocking M8´s. Picture taking and recording still works, but the recocking sounds ugly and might be the warning before something falls apart completely. Mine is a 31xxxx serial number, which I had since January 07, and which was without any problems so far. The recocking issue started after upgrading to the newest firmware some 2 weeks ago. I guess I`ll send it to NJ and since there is some dust under the LCD cover, I´ll try to find out how flexible they are on offering a deal on the upgrades rather than repairing/replacing the old shutter and fixing the screen under warranty. Seems as if the shutter is the achilles heel of the M8, not just because of noise. Link to post Share on other sites More sharing options...
gwelland Posted October 1, 2008 Share #20 Posted October 1, 2008 ... The recocking issue started after upgrading to the newest firmware some 2 weeks ago. ... Hmm, that's exactly my experience too. Maybe it's a firmware issue because it didn't happen before I did the upgrade. This might be something new. Link to post Share on other sites More sharing options...
