ozdavid Posted October 4, 2007 Share #1 Posted October 4, 2007 Advertisement (gone after registration) Last night I had my first experience of Venetian Blinds whilst shooting an Opera with my M8. I received my body new in June and I have installed all of the "downloadable" updates. Although it occurred only once (and after a minute or so the body resumed normal function) I was surprised. I had thought that the recent upgrades had resolved this issue (though having been out of the country working for the last two months I haven't been able to follow the forum as closely as I would have liked). Are others stil experiencing this issue. Are there any suggestions as to anything that I should do (or should not have done!)? Thanks David Link to post Share on other sites More sharing options...

AGeoJO Posted October 5, 2007 Share #2 Posted October 5, 2007 It happens to me from time to time but it is only on the playback, right? The actual files are fine though; so, I just keep on taking pictures.... Link to post Share on other sites More sharing options...
ozdavid Posted October 5, 2007 Author Share #3 Posted October 5, 2007 Thanks Joshua. You're right, it occurred only on play back and the files seem fine. Link to post Share on other sites More sharing options...
M6J Posted October 5, 2007 Share #4 Posted October 5, 2007 It has happened to me twice. No, they have not fixed it yet. I think that it has to do with quickly pressing the shutter release after you turned the camera on after a lens change, but I can't be sure. It is just annoying, it doesn't spoil any pictures.

guy Posted October 5, 2007 Share #5 Posted October 5, 2007 It happens to me relatively regularly (certainly every fortnight or so). Mine are red and black, very snazzy. Link to post Share on other sites More sharing options...
egibaud Posted October 5, 2007 Share #6 Posted October 5, 2007 Hi, I've had it about 5 times since march 1st when I got my M8 Eric Link to post Share on other sites More sharing options...
Shootist Posted October 5, 2007 Share #7 Posted October 5, 2007 Advertisement (gone after registration) I have never seen the blind effect on any of the 3 M8's I've had/have. Not sure when they come up but from what I read it is only when you have instant review turn ON. I don't use that feature so that may be the reason I've never seen them.

vanhulsenbeek Posted October 5, 2007 Share #8 Posted October 5, 2007 On my M8 it happens - when it occurs and that is only intermittently - always after a lens change. Camera on or off during the change: no difference. Link to post Share on other sites More sharing options...
Alberti Posted October 5, 2007 Share #9 Posted October 5, 2007 It happens to me from time to time but it is only on the playback, right? The actual files are fine though; so, I just keep on taking pictures.... It happened to me a few times (black/white stripes) actually after a picture (so the preview had such a nasty effect) but in play-back everything is OK. I have noticed no obvious relationship after a lens change. But otherwise my CV25 (L39 version) with a cut-out/recessed M-bajonet that exposes the lens detection array is a suspect. So I turned off lens detection at a certain moment and at least for some time it goes smooth. albert Link to post Share on other sites More sharing options...
ttriolo Posted October 5, 2007 Share #10 Posted October 5, 2007 The phenomenon has occurred to me maybe half a dozen times since I received the camera. Curiously, when I mentioned the problem to a sales rep at the Leica Berlin store a couple of weeks ago, he said he had never heard of this happening and got a bit of a chuckle over the term "Venetian Blinds". When I explained the problem of alternating b&w horizontal lines on playback, he thought minute and then exclaimed "Oh I get it now"! Link to post Share on other sites More sharing options...

ArtZ Posted October 5, 2007 Share #12 Posted October 5, 2007 There's something in this issue I do not understand. I have two bodies: one bought in June, another in September. Both are configured the same (same menu options, DNG only, Auto WB). I never had the "venetian blind store effect" on the one I bought in June but I got this twice on the one I bought last week in September. Same thing for the "mad scroll wheel". Never happened on the the first one and it happens very often on the second one. On the first, first, one (the one which was replaced 24H after I bought), I saw the "venetian blind store effect" after a few pictures. The serial number was just about a hundred higher than the replacement (the one which has never shown this problem). Both of them had firmware version 1.094 (built in March). The lastest one came with firmware 1.107 (built in August or September). . Link to post Share on other sites More sharing options...
zeitz Posted October 5, 2007 Share #13 Posted October 5, 2007 Venetian Blinds only happen to me when I inadvertantly touch the schroll wheel while the image is still being written to the SD card. The image still plays back normally. Link to post Share on other sites More sharing options...

carstenw Posted October 6, 2007 Share #15 Posted October 6, 2007 Sander,It is not a good idea to leave the camera on during a lens change, believe me. Erm, why don't you explain it instead? Are you talking about sucking in dust or some more nefarious deed? Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted October 6, 2007 Share #16 Posted October 6, 2007 I have changed lenses at least a couple thousand times, never a issue. Please explain Actually being a beta tester for Leica i take the bottom plate off ,remove cards and batteries with the camera on all the time. I try to induce issues. Nothing As far as venetian and mad scroll wheel effect it has been there for at least the last three firmware updates. Leica knows about it and is a fairly common bug but also it is hard to pin down , there is no set of circumstances when operating that it happens that they can point to a exact source. It's a minor bug that has no effect either so hopeful they will pin it down in a firmware fix very soon. You can't fix something if you can't find the cause.

stunsworth Posted October 6, 2007 Share #17 Posted October 6, 2007 Same here. I think the theory is that static from the sensor sucks dust into the camera. However that would mean that the sensor surface would have to be highly charged when not being used. I've never seen any figures describing the voltage on the surface of the sensor when the shutter isn't being fired. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted October 6, 2007 Share #18 Posted October 6, 2007 If anything the amperage would go up only when you shoot because the sensor is turned on, if not shooting it just sits there. Need a engineer for this to explain the current levels but really this sounds like some wives tale to me Link to post Share on other sites More sharing options...
stunsworth Posted October 6, 2007 Share #19 Posted October 6, 2007 Well playing devil's advocate, static electricity doesn't always go away when you switch off the power source, but I agree it seems an unlikely issue. Link to post Share on other sites More sharing options...
ozdavid Posted October 7, 2007 Author Share #20 Posted October 7, 2007 Guy, Thanks for your thoughts on the venetian blinds. For some reason I had thought it had been fixed along the way and I had encountered a revived problem! I'm at least heartened that I'm not alone. I'm off on 4 months leave, travelling Europe via the US starting in a weeks time, for the first time since I started practice as a lawyer over 30 years ago and my M8 and half a dozen lenses (many bought after reading your enthusiatic reports and with help from John Milich's wonderful adapters) are to play a central role in my travels. So resolving this small issue as both minor and widespread has been a considerable relief. Thanks David Link to post Share on other sites More sharing options...
