neelin Posted March 25, 2007 Share #1 Posted March 25, 2007 Advertisement (gone after registration) I had some flaring, wide open that surprised me yesterday, using my canon 50mm f/0.95. After switching to a cv40mm f/1.4 I realized it's not the lens. Upon close inspection there appears to be a 3mm x 3mm chunk missing from one shutter blade. Anyone heard of anything like this? Off it goes this week for repairs. Robert Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Advertisement Posted March 25, 2007 Posted March 25, 2007 Hi neelin, Take a look here M8 Shutter Blade fracture. I'm sure you'll find what you were looking for!
Shootist Posted March 25, 2007 Share #2 Posted March 25, 2007 What other lenses have you used with the M8. From looking at the image you posted there seems to be some type of mark on the shutter release side inside the lens mount area. Have you use any of the collapsible lenses on your M8? Hope everything works out and this doesn't happen to my M8. Link to post Share on other sites More sharing options...
Bill W Posted March 25, 2007 Share #3 Posted March 25, 2007 It looks like my rear bicycle tire when I ran over a decking screw yesterday. I had a piece of the tire missing in that same shape. It looks like something was in the way when it actuated. My concern would be where is the missing piece? This may be why Leica warns us about clearance for certain lens in the M8. Hopefully it is a warranted. Will Leica fix something like this under warranty if they determine it is because of a lens issue? Just wondering. The old passport warranty probably would, I hope the current one will. My incident is attached, I backed out the screw about a half inch, it went all the way through. Made a mess of my bike frame as it went around as well as the rear brake pads befroe I could stop. Welcome, dear visitor!

earleygallery Posted March 25, 2007 Share #4 Posted March 25, 2007 Have you used any of the collapsible lenses? Looks like it could be a 'puncture' from the rear of a lens being collapased against the shutter blade. Link to post Share on other sites More sharing options...
blakley Posted March 26, 2007 Share #5 Posted March 26, 2007 It doesn't look like a puncture to me. It looks like the top edge of one blade caught against something while moving upward, and tore at the point of contact in a "v" shape. Link to post Share on other sites More sharing options...
neelin Posted March 27, 2007 Author Share #6 Posted March 27, 2007 What other lenses have you used with the M8.. I've got the cv 50/1.5, 40/1.4, 28/1.9, 15/4.5 & the Canon 50/0.95 none of which can be rotated/pivoted in any way to get in here (i checked including close/far focus.) I had noticed scuff marks (and not paid any attention to them) on my the blades for months. Last week I had a large grit on my sensor that came off holding the camera upside down & using a simple rubber bulb blower while in sensor clean position (the first time I've ever done anything to clean the sensor). Saturday, I've got this flare happening. Robert Link to post Share on other sites More sharing options...
marknorton Posted March 27, 2007 Share #7 Posted March 27, 2007 Advertisement (gone after registration) What are those scuff marks inside the lens throat? Link to post Share on other sites More sharing options...
jaapv Posted March 27, 2007 Share #8 Posted March 27, 2007 It looks like someting sharp and nasty got caught between the shutter blades. Link to post Share on other sites More sharing options...
steich Posted March 27, 2007 Share #9 Posted March 27, 2007 When cleaning my M8 sensor, I am always frightened I might touch the power switch and thus make the camera close the shutter while the sensor swab is still inside. This might lead to the same pattern of damage... @bill Very proud of you. You even use a RF bike wheel Stefan Link to post Share on other sites More sharing options...
carstenw Posted March 27, 2007 Share #10 Posted March 27, 2007 A sensor swap would damage the outside of the shutter, not between two blades, I am pretty sure. This looks like the shutter was operated with something being too close, and catching. The scuff marks on the left side of the housing make it look like an unsuitable lens was used. Robert, are you sure that at no point a collapsible lens was used? Has anyone other than you used the camera? Link to post Share on other sites More sharing options...
robsteve Posted March 27, 2007 Share #11 Posted March 27, 2007 I notice that your lens mount has the wear marks starting like in the thread about a M8 from Adorama. Is your 40mm stiff to put on and take off? I have read this comment a couple times on the forums and I am wonder in theses lenses have a flaw in their lens mount.

newyorkone Posted April 5, 2007 Share #12 Posted April 5, 2007 Mine has a curved wear line - almost looks like a hair and like it has been rubbing on something - on the bottom shutter blade similar to the one shown in your photo. I'm wondering if eventually it will end up like this?!? Does anyone else see anything on the bottom shutter blade section or is yours uniform across the whole section without any marks? Thanks for any info. Link to post Share on other sites More sharing options...

Thanks for any info. "Frankie's" gone to Solms for the shutter work, I REALLY hope they have their act together & read the work-order to do the warranty "upgrade" at the same time. I really like the M8, not my problems though. So instead of fussing about how things should be, I bought "Franz". With a modicum of luck, either Frankie or Franz will grace my doorstep while the other may be off touring das Vaterland. I reiterate, what a great country (Canada). It allows you to have many cameras at time, but only one wife. Unlike Guy, who's wife is holding a knife to his neck, mine is a little more suble but no less dangerous, ready to garrot me with at rolled up brochure. I really don't know if the fact that it's a Miata PRHT brochure is significant Robert Link to post Share on other sites More sharing options...
gesper Posted April 5, 2007 Share #14 Posted April 5, 2007 I had a similar problem, although the damage was more of a slit than a piece torn off. See this thread for pictures: http://www.leica-camera-user.com/digital-forum/20387-m8-shutter-damage.html?highlight=shutter It's now on its way back to Solms for repair.

ho_co Posted April 5, 2007 Share #15 Posted April 5, 2007 Just curious-- Are you guys sure the cameras are heading back to Solms? Robert, you say you requested the hardware upgrade at the same time, and for that I know that the camera needs to go back. But I would think that a shutter replacement would be doable at Allendale. Thanks! --HC Link to post Share on other sites More sharing options...
adan Posted April 5, 2007 Share #16 Posted April 5, 2007 Howard - I'd expect any service that opens up the "inside" of the camera (i.e. below the RF and behind the shutter) requires "clean-room" service to avoid dust & stuff. I don't think Allendale has a full clean-room, just Solms. Leica US can likely do RF adjustments, but not anything that would expose the below-the-belt innards. As I recall, a noticeable if not significant part of the Euro30M that Leica borrowed for digital development went towards building a clean room to Silicon Valley specs (bunny suits and all) in the Solms plant.

ho_co Posted April 6, 2007 Share #17 Posted April 6, 2007 Thanks, Andy! I had forgotten the need for the clean room. Boy, it's a good thing there are so many older cameras out there to give NJ something to do! Do you suppose that's why Solms is shipping so many out-of-adjustment rangefinders these days? --HC Link to post Share on other sites More sharing options...
AlanG Posted April 6, 2007 Share #18 Posted April 6, 2007 Howard - I'd expect any service that opens up the "inside" of the camera (i.e. below the RF and behind the shutter) requires "clean-room" service to avoid dust & stuff. I can't see why a clean room would be needed. When the shutter opens, it lets in plenty of dust. Isn't the sensor a sealed unit? What else is sensitive to dust? I'd hate to think that basic mechanical repairs on any digital camera involves a clean room. Link to post Share on other sites More sharing options...

It must be satisfying indeed to be the head of a company where customers thank you for not charging them for warranty repairs on their $5000 camera you've kept from them for two and a half months.
