Light leak when changing lenses

[shambla]

Hi everyone. Just got a load of films back from my CL, which I have had for quite a while, but in the past I always used it with just the 40mm. However, I recently picked up the 90mm Elmar-C and so on these latest rolls I have been switching back and forwards between the two lenses and I noticed that most of the frames where the switch occurred have noticeable light leaks on one edge. Has anyone else had this problem with their CL? Thanks

Had it with a Bostonian M2.

didn't try it yet.. i'll try removing my lens on the last roll before sending it to the CLA..

I've never had this problem with my CL, and i change lenses on it. Can you see any leaks with the lens and back off, looking through the back of the camera?

Ok so I finished scanning the 4 rolls I got back the other day and it doesn't seem to be as bad as I thought. There is only one which is really bad, but it just happened to be the first one I scanned where I knew that I had just changed lens. The weird thing is that this shot was taken (and the lens changed) inside a car on an overcast day, but there are several shots where I changed lenses outside in full sunlight and have no obvious light leaks.

My first thought was that maybe the shutter did something weird like not completely closing after the shot, but the light leak was along the right edge of a landscape shot and the CL (if I remember correctly) has a vertical shutter and so surely you would expect the light leak to be visible along the top/bottom edge?

Ah well, considering that this was the only noticeable occurrence of the problem I will ignore it unless it becomes a regular problem. Just another little quirk to add to my CLs list

I've never expereince a light leak with mine and I switch between the 40 and 90 somewhat often.

Sorry to bring up an ancient post but I believe this light leak that I just found on my last roll could be related to the issue in this post. Very bright day out, I took the lens off for just a second and put it back on. This leak happened on frame 11. Then frame 12 was completely black on the negative. It almost looks like on frame 12 I pressed the shutter button while the lens was off and maybe somehow the light spread over to the other frames on either side (11 and 13). But I really don't believe that I did that. I do know that after I put the lens back on I pressed the shutter while the speed was set to bulb and I probably had a 1/3 of a second exposure. Could my theory be right that somehow way more light than normal got to the film and was able to leak out of the normal framelines and into the others?

I am using a CL as well.

Thank you for sharing an example of the film with the light leak. I just went on an afternoon of shooting with a 90mm and 21mm and was constantly changing lenses. I never had that light leak the way you pictured happen on that roll of film. I was also not very careful in some of those switches trying to do so in a hurry with a lot of sunlight to get a particular shot.
