'71 Canon AE-1 with random Light streaks?


Recommended Posts

<p>i have a 1971 canon ae-1 and on several pictures Ive noticed it has produces yellow streaks. Heres an example:<br /><a rel="nofollow" href="http://viewmorepics.myspace.com/index.cfm?fuseaction=viewImage&friendID=5947803&albumID=421442&imageID=7209182">http://viewmorepics.myspace.com/index.cf...</a><br /><br />Any idea as to what causing this,and a possible fix for it?<br>

It happens on random photos,not sequential ones-someone suggested light leak, yet anothe person raised the issue that light leak would be sequential and a shutter problem would more likely be the culprit.Thoughts?Thanks</p>

<p>No such thing as a 1971 Canon AE-1. They were produced starting in 1976.</p>

<p>Looking at your pictures it could be a light leak or a problem with your shutter. It could even be a developing problem or something wrong with the film. Can you tell us more? Without knowing anything further, I am going to take a wild guess that your seals are deteriorating.</p>

<p>If you do not get a good answer here then try the FD forum. They know all about AE-1 Canons.</p>

<p>I'm going to guess light leaks due to bad seals. Check your seals on the rear door specifically the top edge. If your seals are gummy or you have the famous Canon mirror governor "squeal", it's a sure sign you need a full CLA. Light can leak around the door if the camera is held just so in the light. This might explain the position of the artifacts (top camera edge) and the sporadic appearance.</p>

<p>Luis, could you explain what you mean by this, is there something I'm missing? I can clearly see lines going from top of frame to bottom, evenly spaced about 1/4" apart with a slight curve to the left.</p>

<p>Hi Curtis: It seemed that the <em><strong>source</strong></em> of the leak, on the image, originated along the bottom edge since that appears to be the strongest effect of the artifact. On the film, in the camera, this would be upside down as that is how the image is projected thus my idea that the light may have gotten in from the top edge of the camera. It does appear to be sprocket holes but we dont see the rebate edge which would have been useful. If the camera is used, and film advanced, at low light levels, shots taken may not show artifact. a shot taken, not advanced, and later, the back exposed to bright light, might show a leak. In any event, it is just a guess. I imagine the film could have been exposed to light from a leaking cassette, problem at the lab or other reason. A check of the light seals condition could simply help eliminate that as a variable. I see the OP also asked this question on the FD forum and also getting a variety of responses. Interesting problem................Lou</p>

<p>Yep, posted on the fd as well as per a reccomendation. Im going to clean as best I can,or take it to the shop to get it CLA'd. From there Ill have to look at the seals-as noted on here,seems odd light leak would be in some but not others. As far as it being a problem during development, Ive been thinking about the pssibilty and thought about taking different rolls from different cameras into the developers,but if it is that random,theres a good chance itdbe inconclusive.<br>

Going to take a good look at my shutter-seems both threads list that as the main possible culprit.</p>
