Mmmh ... I don't know, what it was ( on the picture ), but it seems to be gone. Don't laugh at me, but if I open the camera and look at it again ... it's gone  But your picture gave me a new idea. What about those two tiny holes beside the rewinding knob ? I haven't notice them yet. Should there be screws inside ? One hole seems to covered more by a rivet than a screw. One seems to be missing on my camera. I definitely need to take the top off to see, where those lead. Any idea, how to remove the top ? There are no screws, nothing |

Dave, I wish, I would be as ingenius as Sherlock Holmes ... or at least as Dr. Watson ? Very well !!! I actually tried that today ... even before reading your excellent comment ... and I shot another test film. What I did, was taping again. I took pictures under the following conditions: 1. Everything taped ( the door and also the filmcounter and ASA window ) 2. Like above but the ASA window untaped 3. Only the door taped ( basically as in the last test before ) 4. Pictures with lens cap mounted 5. Everything taped plus the aperture lever as well 6. Only the counter window taped At all conditions, I forwarded the film directly AFTER taking a picture ... and that's why I decided two more variations: 7. Only counter window taped 8. Nothing taped ... but forwarding the film always immediately BEFORE taking a picture. The result has been ... dissapointing ... or ... I am not capable of making the right conclusions. The light leaking appeared in ALL cases ( or randomly not ) and, what might be the most interesting result, also if the lens is closed. I left the lens cap on and took two pictures after leaving the camera in the sunshine for about a minute. Those pictures look like that:  lens cap light leaking by bokuwanihongasuki, on Flickr Remarkable just, that the shape of the light leak seems to be different, if I take a picture from up to down, as in those two pictures:  Image33 by bokuwanihongasuki, on Flickr  Image16 by bokuwanihongasuki, on Flickr These have been the experiments. So what can we conclude from that ? Being carefully with assumptions and just trying to collect facts, I would say that: It is neither the door nor the counter window nor the ASA window and also not the aperture lever. Therefore, there are actually only two openings in the area of the camera left - both viewer windows, but they should not have any path to the film chamber. Also the bottom plate of the camera does actually not have any connection to the inner part of the body ( I removed it for checking that ). Interesting and a little more difficult - what can we conclude from the lens cap experiment ? From the construction of the camera, I would say, that there can no light leak in from the front lens to the shutter if the lens cap is closed ( it is one closed piece of metal ). Please correct me, if I am wrong, but that would also mean for me, that the light leak can not have been occured during the exposure. The next part in the chain would be the space between the shutter and the inner lens. The aperture is located there ... but I also taped the aperture lever, which practically excludes this area as well. What is left ? The space between the inner lens and the film. I didn't want to sacrifice another fim for your "blocking experiment", so I tried to reverse it. I fired a pretty strong camera flash directly into the film window ( in direction to the lens ). Everything in a completely dark room. I know from similar tests with folders, that even the tiniest hole can not resist this massive light bombardment ... and appears ... but ... nothing. So, Mr. Holmes ... I am running out of ideas  I wish, I could believe in ghosts ... because that's, what is probably sitting in this camera  The restless soul of the last owner ... hahaha ... |

33dollars, the camera has no switch for that. You just switch the aperture lever from AUTO to some aperture, you prefer. Then, the camera goes automatically into manual mode and a flash can be used. It seems, that there is no light lealking from this lever. I checked it with a LED flashlight and also fired a strong camera flash from inside the camera into the direction of the lens while being in a dark room. That usually detects the tiniest hole ... but nothing  |

But 33dollars ... I taped everything ... of course including the door hinges. There could definitely not have leaked any light through that when shooting the second test film ... but the leaks are there as before |

It is opened by pulling the rewind handle up.

I would say, that the shutter is working properly. I tried it more than hundred times while looking through the lens ( at different light conditions ). I can't find anything strange. Also the exposure automatic works excellent. A miracle in my opinion. Totally crazy, inventing such a technology, working completely analog. All pictures have been exposed perfectly ... if there wouldn't be those light leaks.
Also ... if there would be something wrong with the shutter, I would assume, that the light leaking effect would be more or less visable at different apertures, but I can't detect such a connection.
This stupid camera really causes me sleepless nights. I hate it, if I don't know something and can't find it out ... hahaha ...

Thanks Mickey and Dave ... but I actually can't imagine anything, what could cause a light leak from the lens. I checked the lenses ( just from outside though ). They are clean and tightly mounted. If from the lens side, it could only be the shutter ... but I can't find anything wrong about it. My ( sometimes ) ingenius wife, who actually does not understand anything about cameras, assumed, that the shutter might already open during the light measurement ( while pressing the shutter half down ), but I checked that too. Everything seems to work perfectly. Pressing the shutter half down, you can see, that exposure automatic is adjusting the aperture, but the lens is still closed and just opens and close in the proper way, when the shutter button is pressed down completely. There is nothing sticking as often experienced on old folders.
The actually last possibility, I can imagine ( even not verly likely and it wouldn't fit to the location of the light leaks on the pictures ) is ... the film counter window. There is some small piece of metal sticking out right above the film taking spool ( in the slit, where the door will close ). No idea, what function it has, but it might be a weakpoint. I taped everything from outside but if I point my trusted LED flashlight on the film counter window, I can see light coming out at that point. It actually shouldn't reach the film chamber but ... who knows ? Sad, that I forgot to tape it as well today.

First of all, thanks everybody for trying to help me in this issue !!! I shot a second testfilm today, completely taping the door ... and I don't know, if it's a good or bad news ... nothing changed The camera is still leaking light as before. Where the hell is the light coming from ? Looking at the pictures, it should come somewhere from down left ... but I taped everything there. Do I need to give up ? It's a mystery  About 20% of the pictures haven't been affected at all, some slightly and some heavily, horizontally, vertically taken, in strong as in weak light. I can't detect any system in it.  still leaking by bokuwanihongasuki, on Flickr  still leaking 2 by bokuwanihongasuki, on Flickr So sad. Besides the light leaking, this camera is working absolutely marvelous and I have been quite surprised, how exact this selenium meter based auto exposure function is. I tried all kinds of tricky situations ... low light, mixed light, against the light ... it never failed. Much better than the Canonet and it's really a shame, that it is light leaking  Do I cry ? YES, I do ... |

It's in German but easy to understand, I think. The daugther asks: How is the iPad, we gave you for your birthday ? Father: Great. Daughter: Can you handle all the apps ? Father: What apps ? Love it ;D ;D ;D www.wimp.com/dadipad/ |

I would also try to cut back one stop first. You can change it easily by setting the ASA one number higher than what the film really is.
Mickey is also right. A little bit of postproduction ( does not even have to be photoshop ) helps a lot. Film is forgiving and captures a lot of information. Sometimes, you can get even something, if the picture is pretty messed up ( but a correct exposure is of course better ).

Mickey, you are right !!! The picture is of course horizontally mirrored. I guess, it has been already too late last night and my mind became confused  I need to tape the back door and sacrifice another film, I guess. It's just, that I still can't imagine, that it is the back door. It is not deviated and closing properly ... and even if the light seals around the edges became rotten, the door is constructed in a way, that its edges fit into a slot (?) I mean, light can not pass around three corners. Additional, there is also a plate on the inside of the door, pressing on the film and as I said, no light leaking on the perforation of the film, which should become hit first ( or at least also ), I think. But I guess, that's what I need to do ... taping the door for eliminating or approving this theory. As for the second and third possibility, Mickey ... I can't imagine lens flare as a cause, because the effect also occured on pictures in the shadow ( with no bright sky ), but according to a possible mass hysteria ... well ...  ;D ... I feel attacked by that somehow, facing this crazy light leaking stuff ... hahaha ... |

Dave, Mickey, thanks so much for your quick reply. I really appreciate your detective skills  This stuff can drive one crazy I didn't mean the straight thin line. This just appeared on this picture and might be a film issue. I mean the bright leak, coming from the upper right side ... and yes, as the perforation area has not been affected, it should come from the central part of the door ... or not ? Here are two more pictures from the test film.  FH000036 by bokuwanihongasuki, on Flickr  FH000037 by bokuwanihongasuki, on Flickr One is immediately ( less than one minute ) taken after the other. The light leaking does not appear on the second picture, which would be some hint for me, that it is not the lens. The leaking must happen inbetween taking two pictures and if the time is short, not so much light ( or none ) can leak in. Also unlikely, that the leak is somewhere in the area of the film taking spool ( right side of the camera ), because it would effect all pictures ( incl. perforation ) then, because each frame is remaining there for a while ( except, I would shoot 3-4 pictures quickly one after the next ). It's a puzzle ... So you mean the left side of the door ? Where the film canister is inserted ? There is no foam seal on my camera and it looks, that there has never been one. It would also be the wrong side for the leak, wouldn't it ? Or ... I understood wrong Here is a snapshot, how the camera looks from the back side ( open ).  back side by bokuwanihongasuki, on Flickr There is actually not much, what could leak - especially not in the area of the inner film frame. There is also no light leaking inbetween the frames, which also made me thinking, that it actually has to come from the front ( somewhere between the lens and the actual film frame ). There is some kind of "metal chamber" ( I don't know, how to explain it better ), reaching from the film door to the lens. It is a little bit loose ... but if that is causing the leak, wouldn't I be able to detect it with a flash light then ? And I can't |

Hello everybody, I am chasing light leaks again I found a Konica EE matic in the junk box of my favorite camera shop recently and after checking it, I actually couldn't find anything wrong and inserted a first test film. The selenium meter based auto exposure function seems to work still marvelous, but the camera is leaking light from somewhere ... and I really can't imagine, from where that could be Here is one of the pictures from the first test roll:  light leaks by bokuwanihongasuki, on Flickr Light is leaking from the upper right side on most of the pictures ( don't pay attention to the vertical stripe on the left - it is just on this picture ). It is just on the inner frame ( not on the perforation ), which means to me, that the light must come from the front. But ... between the lens and the film, there is just a metal chamber, which can impossibly leak light ( and I couldn't find anything when checking it with a flashlight too ). The shutter also seems to work properly, smooth and closing completely. This camera does have only one shutter speed anyway. Strange though, that the light leaking issue did not occur on pictures, taken with flashlight ... but I don't know, what conclusion I should make from that. Any ideas ? It's actually a fantastic camera and I like it, especially because exposure automatic and rangefinder still seem to work perfectly. Her is a picture of the camera itself as well:  Konica EE matic by bokuwanihongasuki, on Flickr Thanks a lot and cheers from Tokyo, Berndt |
